BASIC POLYMERS
Base polymers with different properties are supplied, suitable for various products, ranging from packaging to household utensils and beyond.
LDPE: low-density polyethylene
This type of polyethylene is particularly popular and is used in the manufacture of flexible single-layer or multi-layer packaging as well as for laminating, foaming and moulding.
MDPE: medium-density polyethylene
For flexible single-layer and multi-layer packaging; for film extrusion.
HDPE: high-density polyethylene
A solid and strong raw material with a wide range of applications: for the manufacture of flexible single-layer and multi-layer packaging, pipes, bottles, canisters, and geomembranes.
LLDPE: linear low-density polyethylene
A highly popular raw material combined with other polyethylene, which can be used to make both flexible and rigid packaging as well as tubes and various containers.
mPE: metallocene polyethylene
The use of metallocenes allows for the creation of shrink films of extremely high quality, and multilayer films with exceptional mechanical and optical properties.
Polypropylene is widely used to manufacture pipes, packaging and medical supplies. With an appropriate grade and product design, it is used for demanding packaging applications, including containers suitable for microwaves, dishwashers or hot filling, as well as medical supplies intended for high-temperature disinfection.
PPH: polypropylene homopolymer
Used for the manufacture of consumer goods, food boxes, boxes, and sheets.
PPC: polypropylene impact copolymer
Polypropylene impact copolymer offers good impact resistance, including at low temperatures. Suitable grades are used for injection moulding.
PPR: random copolymer polypropylene
Clear grades of polypropylene random copolymer are widely used for packaging where good product visibility is important.
PET: polyethylene terephthalate
Widely used to manufacture disposable packaging and bottles. PET can be recycled; the recyclability of a particular package depends on its design, additives and appropriate collection and sorting.
PVC: polyvinyl chloride
An indispensable material in the construction industry for the manufacture of durable pipes or flexible cable insulation as well as other plastic products.
GPPS: general purpose polystyrene
Crystal-like, widely used for the manufacture of household items and packaging (including foam packaging).
HIPS: high impact polystyrene
Owing to its physical and mechanical properties, this is chosen for the manufacture of TV sets, refrigerators, and other household appliances.
EPS: expandable polystyrene
Used for insulating buildings and manufacturing thermally insulating food packaging.
ENGINEERING PLASTICS
Engineering plastics, which are widely used in many industries, are supplied.
PC: polycarbonate
Transparent engineering plastic characterised by high impact strength and excellent optical properties. It is widely used in the automotive industry, construction, manufacture of home appliances, coffee makers, sound recording media, sunglasses, and medical goods.
ABS: acrylonitrile butadiene styrene
A raw material of natural and ivory colour that can be pigmented. Owing to its strength and impact resistance, it is recommended for use in the manufacture of electrical equipment (enclosures, keyboards, and household items).
PMMA: polymethyl methacrylate
A transparent thermoplastic valued for its good optical properties. It is used to manufacture LCD components, windows, display barriers and certain medical devices. Where greater impact resistance is required, impact-modified PMMA grades are selected.
SAN: styrene acrylonitrile
Hard, rigid and transparent material with good resistance to high temperatures. This makes it ideal for use in the manufacture of transparent cosmetic containers, kitchen bowls, and refrigerator fasteners.
ASA: acrylonitrile styrene acrylate
A possible alternative to ABS, which features increased weather resistance and is widely used in the automotive industry and for 3D printing.
TPE: thermoplastic elastomers
A flexible material suitable for moulding, manufacture of sports goods, yoga mats, pen and screwdriver handles, erasers, various cell phone accessories, beach accessories, and so on.
TPU: thermoplastic polyurethane
A thermoplastic elastomer combining rubber-like elasticity with thermoplastic processing capabilities. Suitable TPU grades can replace PVC and offer good ageing resistance. TPU is used to manufacture footwear, safety shoes, handles, wire insulation and cable sheathing.
TPO: thermoplastic polyolefin
Thermoplastic polyolefins are used to manufacture automotive bumpers, trim and other components. The blend composition is selected to balance stiffness, impact resistance and processing properties.
TPV: thermoplastic vulcanizates
Thermoplastic vulcanizates combine rubber-like elasticity with thermoplastic processing capabilities. Suitable production scrap can be reprocessed. TPVs are used in the automotive industry and for electrical wire insulation.
SBR: styrene butadiene rubber
A synthetic rubber valued for its abrasion resistance and used in some products as an alternative to natural rubber. It is used to manufacture gaskets, mats, cushioning components and parts that protect against wear between metal surfaces.
PA: polyamide
Polyamide, also known as nylon, includes different types, such as PA6, PA66 and PA12. Different PA types allow the material to be selected according to the mechanical properties required for the component, operating conditions and manufacturing process. PA can be coloured with pigments, filled with talc, reinforced with glass fibre and used in automotive and other industrial applications.
SEBS: styrene–ethylene/butylene–styrene block copolymer
SEBS is used to produce thermoplastic elastomers suitable for moulding and extrusion. Depending on their formulation, they can be transparent or coloured with pigments to the customer’s requirements. They are used to manufacture automotive wire insulation, interior components and handles.
POM: polyoxymethylene
Mainly used for injection moulding, where stiffness and precision are required. The natural raw material is white and opaque but it can be coloured with pigments. POM is used for the manufacture of furniture handles, zippers for clothes, parts for toys, and parts for electronic devices and installations.
PVC: polyvinyl chloride
A cheap plastic used for the manufacture of pipes and profiles like doors and windows. It is also used for bottles, non-food packaging, and so on. According to need, it can be either rigid or flexible.
