Fachwissen Fluoropolymers



The completely fluorinated polymer PTFE is the most widely used fluoropolymer and based on its unique properties established as an undispensible construction material in modern industries. The extraordinary properties of PTFE are due to its resistence to most chemicals, its broad service temperature range, the excelent electrical properties, the persisting to embrittlement, the ageing resistance and its high purity.

This technical brochure informs about the quality requirements and test conditions, which are necessary to assess semi – finished goods made from PTFE resins, which are essential for high quality PTFE products.

This technical brochure is edited by the Fluoropolymergroup of pro-K and provides the present state of knowledge as by March 2016.
