AKROTEK®
AKROTEK® PK-VM GF 30 8 natural (6983) is a 30% glass fibre reinforced polyketone with 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 corresponds to the European food guideline EU 10/2011 and to the American FDA 21 CFR. This grade is suitable for parts of kitchen and household appliances. Please note that the material is NOT suitable anymore for drinking water contact and does NOT meet the requirements according to KTW, DVGW W270, ACS, WRAS as well as NSF61.

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.
