PK-VM GF 50 black (8688)

PK GF50

AKROTEK® PK-VM GF 50 black (8688) is a 50% glass fibre reinforced polyketone with very high stiffness and strength. PK is characterized by its outstanding media resistance, which qualifies it to be used for components that are in contact with chemicals. The material can be laser marked. This type was developed as the successor to PK-VM GF 50 black (5394) in order to meet the requirements for a larger processing window during processing.
