Tolerances for sintered PTFE-products

Preamble

The fully fluorinated polymer PTFE is the most widely used fluoropolymer and based on its unique properties is established as an indispensable construction material in modern industries.
The main extraordinary properties of PTFE are resistance to most chemicals, a broad service temperature range, the excellent electrical properties, resistance to embrittlement, ageing resistance and very high purity.
This technical brochure provides information on the tolerances for sintered products made from PTFE, which are essential for high quality PTFE products.
This brochure replaces and in parts respectively augments the brochure „quality requirements, test guidelines and tolerances“ for PTFE products edited in 1993 by the „Gesamtverband Kunststoffverarbeitende Produkte” (GKV).
