Abstract
This specification covers glass fabric impregnated, coated, and sintered on both sides with PTFE to a specified maximum nominal thickness. It does not pertain to structural fabric, single-sided PTFE coatings, or materials used for laminates. The PTFE-coated glass fabric is for electrical, chemical, and mechanical uses. The base material used in the manufacture of the products of this specification shall be a woven glass fabric. The glass fabric is impregnated or coated with polytetrafluoroethylene. When necessary, additives are used to aid the dispersion to achieve the required properties and performance of the final product. The glass fabric shall be tested for color, thickness, breaking strength, edge tear, conductivity, percent PTFE, smoothness, and porosity.
Scope
1.1 This specification covers glass fabric impregnated, coated, and sintered on both sides with PTFE to a nominal thickness of 0.318 mm (0.015 in.) or less.
1.2 The PTFE-coated glass fabric is for electrical, chemical, and mechanical uses.
1.3 The PTFE-coated glass fabric of this specification does not pertain to structural fabric, single-sided PTFE coatings, or materials used for laminates.
1.4 The values stated in SI units as detailed in .
Note 1—There is no ISO standard that covers information included in this specification. The dielectric test is mentioned in ISO 12086-2 and ISO 13000–1 and 2.
