AKROTEK®
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.

The values mentioned are recommendations. We only recommend desiccant / dry air dryers or vacuum dryers. Too long a drying time and the resulting residual moisture content below the lower limit can lead to filling problems and surface defects. The specified drying time refers to closed and undamaged bagged material. When processing from previously opened bags or from octabins with polyolefin inliners, a longer drying time may be necessary. It is recommended to check the residual moisture content after the drying process.
