High-performance thermoplastics

PA (POLYAMIDES)

 reinforced with LONG fibres (*)

Special characteristics:

An effective alternative when it is impossible to obtain required properties with conventional polymers.
Impact-resistant even at low temperatures;
Creep-resistant;
Good fatigue resistance;
Mechanical resistance and modulus properties at high temperatures;
Less tendency to warp following injection moulding, thanks to reduced anisotropy. Reduced anisotropy is also found in the mechanical properties.
(*) these reinforcement fibres are 10 or 12 millimetres long, while the average length of fibres dispersed in the granules of conventional short glass fibre-reinforced thermoplastics is around 1 millimetre. Commonly used reinforcements are primarily glass and carbon fibres.

PEEK (POLYETHERETHERKETONE)

available both non-reinforced and carbon fibre- or glass fibre-reinforced

Special characteristics:

High temperature, resistant at 240°C (temperature resistance rises to a maximum of 300°C if reinforced with 30% glass fibres, for example);
High resistance to gamma rays;
Very high resistance to sterilisation cycles;
Exceptional dimensional stability;
Good resistance to chemicals;
Good abrasion resistance;
Electrical insulation.

PPA (POLYPHTHALAMIDE)

Glass fibre- or carbon fibre-reinforced

Special characteristics:

Developed to obtain improved properties compared to conventional aliphatic polyamides (PA6 and PA66). Offers a combination of very good mechanical and heat properties with an excellent cost/performance ratio;
High melting point;
Good rigidity at high temperatures;
High continuous operation temperature;
Excellent mechanical properties;
Good resistance to chemicals;
Good dimensional stability;
Relatively low moisture absorption;
Excellent surface appearance with special mineral content (up to 60%).

PPS (POLYPHENYLENE SULPHIDE)

Available both non-reinforced and glass fibre-reinforced

Special characteristics:

One of the most temperature-resistant thermoplastics there is. Some grades of reinforced PPS reach a heat deflection temperature (HDT) of 270°C.
Continuous use temperature up to 240°C;
Resistance to temperature peaks up to 270°C;
Inherently self-extinguishing;
Very high resistance to chemicals (insoluble in all known solvents under 200°C);
Very low water absorption;
Very high flow resistance, even at high temperatures.
