PK (Polyketone)

Polyketone is a thermoplastic material with a good balance between mechanical- thermal and chemical properties. Polyketone has almost equal strength as POM is dimensional stable and has imroved impact wear and chemical resistance compared to POM.

PK is FDA approved (Some colors may not be tested according to EC1935. Please contact our material expert for further information).

Chemical effects

Excellent: No attack, possibly slight absorption. No effect on mechanical properties.

Good: Slight attack by absorption. Some swelling and small reduction in mechanical properties likely.

Fair: Moderate attack of appreciable absorption. Material will have limited life.

Unsatisfactory: Material will decompose or dissolve in a short time.
