Basic dataStandard ID: GB/T 39714.1-2020 (GB/T39714.1-2020)Description (Translated English): Plastics - Polytetrafluoroethylene(PTFE) semi-finished products - Part 1: Requirements and designation Sector / Industry: National Standard (Recommended) Classification of Chinese Standard: G31 Classification of International Standard: 83.140.01 Word Count Estimation: 11,127 Date of Issue: 2020-12-14 Date of Implementation: 2021-07-01 Quoted Standard: GB/T 2035; GB/T 39714.2; ISO 20568-1 Adopted Standard: ISO 13000-1-2005, MOD Regulation (derived from): National Standard Announcement No. 28 of 2020 Issuing agency(ies): State Administration for Market Regulation, China National Standardization Administration Summary: This standard specifies the requirements and naming of semi-finished products of polytetrafluoroethylene (PTFE). This standard applies to the production of semi-finished polytetrafluoroethylene containing up to 1% of comonomers. The PTFE used to make semi-finished products can be new materials, or reprocessed or recycled resins. The maximum amount of pigment or colorant added is 1.5% by mass, which is also suitable for processing conditions of different forms of unfilled PTFE products. This standard divides semi-finished products into four grades based on the difference in tensile strength and tensile breaking strain. Semi-finished products can be divided into processing type (P type), dimensionally stable type (S type), and can also be designated as electrical type (E type) or other types in different applications.
