Susta®PEEK is a very high performance temperature PEEK™ (Poly Ether Ether Ketone) formula.

It is a semi-crystalline thermoplastic with excellent chemical resistance to a wide range of chemical environments; even at elevated temperatures, although concentrated sulphuric acid dissolves PEEK™.

​

Susta®PEEK is a unique engineering material with a glass transition temperature of 143°C and a melting temperature of 343°C. Independent tests have shown PEEK™ exhibits a heat distortion temperature up to 315°C in glass fibre filled and a continuous use temperature of 260°C.

 

Susta®PEEK has excellent friction and wear properties which are optimised in the specially formulated tribological grade, which contains 10% Graphite, 10% PTFE and 10% Carbon Fibres.

 

Susta®PEEK is a highly stable polymer and requires no flame-retardants or additives to achieve a UL 94 V-O rating at 1.45mm thickness. The composition and inherent purity of PEEK™ results in extremely low smoke and toxic gas emission in fire situations.

 

Susta®PEEK is not chemically attacked by water or pressurised steam and retains a high level of mechanical properties.

 

Susta®PEEK has excellent electrical properties and low levels of extractable ionic species and outgassing.
