Acrylonitrile butadiene styrene-ABS is a common thermoplastic used to make light, rigid, molded products. It is a copolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15% to 35% acrylonitrile, 5% to 30% butadiene and 40% to 60% styrene. The result is a long chain of polybutadiene criss-crossed with shorter chains of poly(styrene-co-acrylonitrile).

The nitrile groups from neighbouring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The styrene gives the plastic a shiny, impervious surface. The butadiene, a rubbery substance, provides resilience even at low temperatures. ABS can be used between −25 °C and 60 °C.
High impact strength
Good paintability
Resistant to chemicals
Low delay


Polyamides are thermoplastics. They consist of organic macromolecules (polymers) whose monomer units are linked by polycondensation between a carboxyl group and an amino group. The resulting bond is called a peptide bond. It can be hydrolytically cleaved again.
High heat resistance
High rigidity
High strength
High abrasion resistance
Good electrical insulation properties


Polyamide 66 has a similar property profile to polyamide 6, but has a higher heat deflection temperature and improved strength values.
Chemical resistance
High water absorption
High work capacity
High abrasion resistance


Polybutylene terephthalate is a thermoplastic material. It is a polyester and has similar properties to PET, but is more suitable for injection moulding due to its more favourable cooling behaviour.
Very high dimensional stability, significantly better than that of POM or PA
Good sliding properties and wear resistance
High strength and rigidity (but worse than POM)
Good chemical resistance
Not suitable for use in hot water (hydrolytic molecular weight degradation)


Polycarbonates are synthetic polymers from the polyester family - made from carbonic acid and diols.
Very high impact strength values
Good strength
Good toughness
Low hydrolysis resistance
Dimensional stability


Polyoxymethylene is a semi-crystalline thermoplastic.
High strength and rigidity
High resilience
Low water absorption
Good gliding behaviour


Polypropylene is a semi-crystalline thermoplastic and belongs to the group of polyolefins. Polypropylene is obtained by polymerising the monomer propene with the help of catalysts.
