1.1 This specification covers polytetrafluoroethylene (PTFE) filled molding compounds made with virgin PTFE resins defined in Specification D 4894 , as Types II and III.<\/p>\n
Note<\/span> 1This specification can be used as a model for other PTFE compounds having particulate fillers that can survive the sintering temperatures of PTFE as can those listed in this specification. This specification is restricted to virgin PTFE base resin for technical reasons. Recycled or reprocessed material cannot be processed successfully.<\/p>\n Note<\/span> 2The properties measured on commercially fabricated parts may differ from the listed values for samples prepared by the procedures given in this specification, depending on part geometry and processing parameters.<\/p>\n Note<\/span> 3There is no ISO equivalent to this specification.<\/p>\n 1.2 The values stated in SI units are to be regarded as standard.<\/p>\n 1.3 The following statement applies to the test method portion, Section 12, of this specification:<\/span> This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span> See Note 5 for a specific warning statement.<\/span><\/span><\/p>\n D4745-08 Standard Specification for Filled Compounds of Polytetrafluoroethylene (PTFE) Molding and Extrusion Materials<\/b><\/p>\nPDF Catalog<\/h4>\n
