Polyketone High-Performance Thermoplastic Polymer
Polyketone (PK) is a high-performance thermoplastic polymer with a high melting point. This is the result of polar ketone groups in the polymer backbone creating a strong attraction between polymer chains. Polyketone (PK) meets the demands of a wide range of applications and has been enjoying somewhat of a renaissance thanks to its environmental credentials relative to other polymers. This is due to co-monomer CO (carbon monoxide) in the structure of the polyketone. An industrial “waste” gas which can contribute to global warming, it bonds with a polymer to form a highly favourable monomer.
Popular applications for polyketone include gear wheels, valves, bearings, fuel lines and filters, quick connectors, switches and housings. It is most commonly found in the manufacturing, automotive and electrical sectors.
High-Performance Thermoplastic Polymers
Polyketone has several properties which no other polymer has in this combination. Freshly injection-moulded polyketone has the greatest yield strain (over 30 %) compared to all other semi-crystalline polymers, virtually independently of moisture. This tremendous elasticity gives many components made of PK a high degree of safety in the design phase.

AKROTEK® PK – Your Design Choice
Due to its very high tensile strength, AKRO-PLASTIC AKROTEK® PK is a great choice for designs that need to sustain constant mechanics even under changing climatic conditions. Polyketone also possesses the ability to deform elastically and reversibly. This results in a product with an extremely low creep tendency when used in combination with glass fibres. AKROTEK® PK is available with a glass fibre content up to 60 %. This enables it to resist high stresses under strong chemical effects.
