1、Designation: D 7193 05Standard Specification forUnsintered Pigmented Polytetrafluoroethylene (PTFE)Extruded Film or Tape1This standard is issued under the fixed designation D 7193; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, th
2、e year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers unsintered, pigmented, ex-truded films or tapes manufactured from polytetrafluoro
3、ethyl-ene, in nominal thicknesses from 0.025 mm (0.001 in.) to 0.51mm (0.020 in.), that are 97 % virgin PTFE in compositionprior to introducing pigments.1.1.1 The use of recycled PTFE for production of unsinteredextruded films or tapes has not been identified at this time.When commercial usable proc
4、esses and materials are avail-able, this specification will be revised to include recycledmaterials.1.2 The values stated in SI units are detailed in IEEE/ASTMSI-10 are to be regarded as the standard. The values given inparentheses are for information only.1.3 This standard does not purport to addre
5、ss all of thesafety problems associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.NOTE 1Although this specification and ISO/DIS 13000-1 (1997) andISO/DIS
6、 13000-2 (1997) differ in approach or detail, data obtainedrelating to specific properties, using either are technically equivalent.NOTE 2This specification is intended to be a complement to Speci-fication D 6585, as the materials covered herein vary significantly enoughdue to their additives to war
