Material

Our plastic solutions are made using a wide range of synthetic materials, with polymers as the main component. This allows us to create products with various shapes, while also focusing on their durability and flexibility. Poly Plast does not compromise with quality, that is why we choose to work only with the best materials on the market.

There is not just 'one FRP'. Different resins, glasses and the type of processing enable the manufacture of various laminate types which sometimes have drastically different physical and chemical properties . Different laminate types are used, depending on the requirement profile and component. This ensures maximum flexibility compared with other materials.

In addition to components made entire from FRP, POLY PLAST also manufactures products with an inner thermoplastic liner.

The material compound of thermoplastic liner and glass-fibre reinforced plastic (FRP) combines the high chemical stability of special thermoplastics with the excellent mechanical and thermal parameters of FRP. The design and selection of the material partners allows fine-tuning the composite construction to the requirements of special applications much more precisely than it is possible with a different material.

Poly Plast

PE(polythene)

  • Products made of polyethylene (PE 100 and PE 100-RC) are characterised by high toughness and excellent chemical resistance. PE used from -40 °C to +60 °C. Other characteristics of products made of PE 100 and PE 100-RC include the following:
    -   good resistance to wear
    -   excellent electrical insulation
    -   high vibration damping

  • For decades now, products made of PE 100 and PE 100-RC black have proven reliability when used outdoors. The addition of particular carbon black types (approx. 2 %) ensures light and weather resistance. Products made of PE 100 and PE 100-RC black are unaffected by natural UV radiation.

  • Electrically conductive polyethylene (HDPE-el ESD) is a material that conducts electrical charges because conductive particles (carbon black) have been added to it. Products made of this particular material have integrated stabilisers that counteract natural UV light and are also suitable for outdoor applications.
    Due to their unique electrical properties, these products are particularly well suited to transporting highly flammable media or dust. HDPE-el ESD can also be used in areas where sparking from electrostatic charging needs to be prevented due to explosion protection requirements.

  • To comply with purity requirements, Polyplast makes products made of natural HDPE as well.

PP(polyproplene)

  • Polypropylene (PP) is a semi-crystalline thermoplastic near/similar to HDPE but with higher stiffness, strength, and hardness levels.

  • PP is a largely-polar, partially crystalline thermoplastic with a crystallinity of 60% to 70% and a density of 0.90 to 0.91g/cm3, which is amongst the lowest for all plastics.


  • Polypropylene is available in two main grades, Polypropylene homopolymer and Polypropylene copolymer. Both have very similar properties but appearance and performance differences are distinctive between the two types

  • An excellent chemical resistance also characterizes it. PP features increased rigidity, especially in the upper service temperature range (up to +95°C). However, below the freezing point, PP is very sensitive to impact

  • (use at temperatures below - 5 °C should be avoided). Products made of PP are also characterized by the following:
    -   a low density of 0.91 g/cm3
    -   relatively high surface hardness
    -   electrical insulation properties
    -   high creep strength

  • It is generally available in three advanced forms
    -   PP-Homopolymer(PP-H)
    -   PP-Copolymer(PP-C)
    -   PP-random Copolymer(PP-R)

  • Polypropylene is used in many different applications from industrial, consumer goods to display applications. Polypropylene is used extensively in manufacturing chemical tanks, structural tank, liners and covers. Other common applications include, industrial battery covers, pump components and impellers. Polypropylene sheeting is also used for hygienic cladding applications. FDA Food approved makes this an ideal plastic material for food processing applications and components. Polypropylene is reasonably economical, and can be made translucent when uncolored; the natural finish is a milky white finish. Polypropylene is difficult to bond with adhesives due to its chemical resistant properties and welding and mechanical fixing is recommended.

  • PP is the ideal material for use in Sugar Industry, Solar Cell, Steel Plant, Battery Industry, Pharma Industry, Acid regeneration, Non-Ferrous, Chemical Industry, Fertilizer Plant as chemicals are used at high temperatures in these areas.

PVDF

  • Polyvinylidene fluoride or polyvinylidene difluoride (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. Its chemical formula is (C2H2F2)n.

  • PVDF is a specialty plastic used in applications requiring the highest purity, as well as resistance to solvents, acids and hydrocarbons. PVDF has low density 1.78 g/cm3 in comparison to other fluoropolymers, like polytetrafluoroethylene.

  • It is available in the form of piping products, sheet, tubing, films, plate and an insulator for premium wire. It can be injected, moulded or welded and is commonly used in the chemical, semiconductor, medical and defence industries, as well as in lithium-ion batteries.

  • PVDF is a highly crystalline non-reinforced plastic that combines good mechanical, thermal, and electrical properties with excellent chemical resistance. Besides, it possesses good radiation resistance, which makes it ideal for high-end applications in semiconductors, pharmaceuticals, life science, and the photovoltaic industry.

  • PVDF can be processed without additives, which gives it excellent leaching behaviour. PVDF is manufactured under controlled purity conditions using carefully selected raw materials. Areas of application for these products include storage and transportation tanks and apparatuses requiring high media purity and leaching behaviour standards.

  • PVDF can be equipped with electrically conductive particles, especially for the electrical industry and explosion-proof areas. The conductive PVDF-el ESD (electrically conductive or electrostatic discharge) has a lower surface resistance, which prevents electrostatic charging.

  • PVDF Flex is an excellent alternative to well-known, conventional fluoropolymers. When it comes to processing, significant rationalisation effects can be achieved through increased flexibility, especially in bonded to steel linings and confined spaces or small

ECTFE

  • ECTFE (ethylenechlorotrifluoroethylene)
    is a copolymer of ethylene and chlorotrifluoroethylene. It is a semi-crystalline fluoropolymer
    (a partially fluorinated polymer) designed to provide chemical resistance in heavy-duty corrosion applications.

  • ECTFE is resistant to acids at high concentrations and temperatures, caustic media, oxidizing agents and many solvents. It has similar chemical resistance to PTFE. A chemical resistance table, based on immersion tests, has explored this further. Permeation of large molecules is slow in fluoropolymers and thus is not relevant in the final application. Small molecules, however, may permeate through the polymer matrix at a relevant time. In lining or coating applications, the permeation of certain small molecules determines the lifetime of anti-corrosion protection. H2O, O2, Cl2, H2S, HCl, HF, HBr, N2, H2, CH3OH, etc. are relatively mobile in a polymer matrix and lead to measurable effects. Permeation resistance is significant for lining and coating applications, because permeating species may attack underlying mechanical layers, such as fiber reinforced plastic or steel. This high permeation resistance to small molecules is a consequence of the free volume occupied by the chlorine atom in the polymer chain.

  • ECTFE has a continuous usage temperature range between typically –76 °C and +150 °C (–105F to +300F).

  • ECTFE possesses a unique combination of properties resulting from its chemical structure,
    which consists of a copolymer with ethylene and chlorotrifluoroethylene arranged alternately.

  • Furthermore, ECTFE is known for its sound permeation barrier for many chemicals. Its excellent welding properties and thermoplastic formability also make cost-saving and straightforward processing possible,
    both in the workshop and on-site. Compared to PVDF, ECTFE has better chemical resistance, especially when exposed to lyes

FEP

  • Fluorinated ethylene propylene (FEP) is a copolymer of hexafluoropropylene and tetrafluoroethylene.
    It differs from the polytetrafluoroethylene (PTFE) resins in that it is melt-processable using conventional injection moulding and screw extrusion techniques.
    Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon FEP. Other brand names are Neoflon FEP from Daikin or Dyneon FEP from Dyneon/3M.

  • FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP and PFA both share PTFE's useful properties of low friction and non-reactivity, but are more easily formable. FEP is softer than PTFE and melts at 260 °C; it is highly transparent and resistant to sunlight.

  • FEP, which is a fully fluorinated plastic, offers outstanding corrosion resistance. It performs reliably over the enormous range of temperatures between -190 °C and +205 °C and can be used in numerous industrial applications. Flexibility, thermoformability and optimum welding properties mean POLY PLAST made FEP products can be manufactured reliably at low costs.

They are copolymers of tetrafluoroethylene (C2F4) and perfluoroethers (C2F3ORf, where RF is a perfluorinated group such as trifluoromethyl (CF3)). The properties of these polymers are similar to those of polytetrafluoroethylene (PTFE). Compared to PTFE, PFA has better anti-stick properties and higher chemical resistance, at the expense of lesser scratch resistance.

  • PFA is commonly used as a material for piping and as fittings for aggressive chemicals, as well as the corrosion-resistant lining of vessels in the chemical-processing industry. Typical applications include the construction of gas scrubbers, reactors, containment vessels and piping.

  • PFA is the highest grade plastic in the portfolio. It is suitable for a vast spectrum of applications, thanks to its resistance to almost any medium and its temperature range of -190 °C to +260 °C. This means it can be offered as a solution even for harsh chemicals at high temperatures such as 150 °C sulfuric acid 70% concentration. The products made of PFA are also available in HP (High Purity) quality. The HP quality means it can be used for applications in semiconductors, pharmaceuticals, and food industries that require high purity levels.

  • The PFA lining can be used up to an operating temperature of 260 °C and shows excellent chemical resistance against condensation media like H2SO4, HCl and HF, typically present in power plant applications.

It is commonly used in industries such as aerospace, construction and marine to build structures that require added resistance to force in order to prevent deformation. Fiber-Reinforced Plastic is useful in terms of corrosion protection because it helps in preventing corrosion due to force application and deformation such as stress corrosion cracking.

  • Fiber-Reinforced Plastic may also be known as Fiber-Reinforced Polymer.

  • Forming processes :
    -   Bladder moulding
    -   Compression moulding
    -   Autoclave and vacuum bag
    -   Mandrel wrapping
    -   Wet layup
    -   Chopper gun
    -   Filament winding
    -   Pultrusion
    -   Resin transfer moulding

  • Applications :
    Fibre-Reinforced Plastics are best suited for any design program that demands weight savings, precision engineering, definite tolerances, and the simplification of parts in both production and operation. A moulded polymer product is cheaper, faster, and easier to manufacture than a cast aluminium or steel product, and maintains similar and sometimes better tolerances and material strengths.

  • Glass-fibre-reinforced polymers
    Engine intake manifolds are made from glass-fibre-reinforced PA 66.

  • Advantages this has overcast aluminium manifolds are:
    -   Up to a 60% reduction in weight
    -   Improved surface quality and aerodynamics
    -   Reduction in components by combining parts and forms into simpler moulded shapes.
    -   Automotive gas and clutch pedals made from glass-fibre-reinforced PA 66 (DWP 12–13)

  • Advantages over stamped aluminium are:
    -   Pedals can be moulded as single units combining both pedals and mechanical linkages simplifying the production and operation of the design.
    -   Fibres can be oriented to reinforce against specific stresses, increasing the durability and safety.
    -   Aluminium windows, doors and façades are thermally insulated by using thermal insulation plastics made of glass fibre reinforced polyamide. In 1977, Ensinger GmbH produced first insulation profile for window systems.
