General Description:  

General Description : A high performance semi-crystalline thermoplastic produced from the monomers of carbon monoxide, ethylene and propylene. The polar ketone groups in the polymer backbone of this material gives rise to a strong attraction between the polymer chains and a melting point of 220°C. This aliphatic polyketone offers a range of outstanding characteristics including excellent dynamic resilience, good barrier properties, good tribological properties, excellent chemical resistance, good hydrolysis resistance and shorter cycle times.

Applications in industrial, automotive and electronics including gear wheels, bearings, valves, fuel lines, hoses, connectors, fuse holders and housings.
