AKROTEK® PK-VM GF 30 black (8655) is a 30% glass fiber reinforced Polyketone with average stiffness and strength. Due to its very good media resistance, the material is suitable for the use in applications that carry cooling water. The material can be laser marked. This type was developed as the successor to PK-VM GF 30 black (4896) in order to meet the requirements for a larger processing window during processing.
