VESTAKEEP® Film 0FH90

About
VESTAKEEP® film 0FH90 is a cast film based on 100% unreinforced polyether ether ketone (PEEK). The film is amorphous with a matte/glossy surface finish. The material features low extrusion related internal stresses and is ideal to thermoform 3D parts from, e.g. small speaker membranes. Application examples: electrical insulation thermoformed thin parts loudspeaker membranes Important notice: Amorphous PEEK film undergoes crystallization at above its glass transition temperature around 150°C. This should be taken into account upon processing as well as in final applications. The crystallization can only be reversed by heating to the melt followed by quenching.&&
