PK-VM GF 30 LT black (8653)PK GF30

AKROTEK® PK-VM GF 30 LT black (8653) is a 30% glass fibre reinforced, lasertransparent low viscous polyketone with high stiffness and strength. Due to its very good media resistance, the material is suitable for use in applications that carry cooling water. This type was developed as the successor to PK-VM GF 30 LT black (8530) und PK-VM GF 30 LT black (6934) in order to meet the requirements for a larger processing window during processing.
