PK-VM GF 30 7 HU black (8695)PK GF30

AKROTEK® PK-VM GF 30 7 HU black (8695) is a 30% glass fibre 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 PK-VM GF 30 schwarz (8655) was developed as the successor to meet the requirements for a larger process window during processing.
