Standard Specifications for PTFE & Filled PTFE
PolyTetraFluoroEthylene-PTFE is standardized worldwide by many countries as ASTM (USA) ISO (Europe), JIS (Japan), Indian Standard (IS), & British Standard (BS). The research Institute & Industries mostly follow ASTM & ISO standards for standardizing & defining PTFE Resin / Primary Forms, Test Procedure of PTFE Resin / Primary Forms & PTFE Products / Secondary Forms.
