ASTM D7193-17 (2022) PDF

Full title and description

Standard Specification for Unsintered Pigmented Polytetrafluoroethylene (PTFE) Extruded Film or Tape — a concise ASTM specification that defines composition, dimensional range and required property tests for unsintered, pigmented extruded PTFE films and tapes used in sealing, insulation and other industrial applications.

Designation: D7193 −17 (Reapproved 2022).

Note: this specification is intended as the companion for pigmented products to the unpigmented PTFE specification (D6585).

Abstract

This specification covers unsintered, pigmented, extruded PTFE films or tapes in nominal thicknesses from 0.025 mm (0.001 in.) to 0.51 mm (0.020 in.). It sets composition and test requirements (physical and electrical where applicable) for products made from ≥99 % virgin PTFE prior to introduction of pigments and lists referenced test methods and terminology standards. The standard complements ASTM D6585 (unpigmented products).

• Publication date: April 30, 2022 (reapproved 2022 edition).
• Publisher: ASTM International (American Society for Testing and Materials).

• Edition / version: D7193‑17 (Reapproved 2022).
• Number of pages: 4 pages (concise specification).

Scope

The specification applies to unsintered, pigmented, extruded PTFE film or tape manufactured from polytetrafluoroethylene in nominal thicknesses from 0.025 mm (0.001 in.) to 0.51 mm (0.020 in.), with material that is ≥99 % virgin PTFE in composition prior to addition of pigments. It excludes sintered PTFE and refers users to D6585 for unpigmented equivalents; it also notes that recycled PTFE was not identified for use at time of publication. The document lists referenced ASTM and ISO test and terminology standards that define required test methods and measurements.

Key topics and requirements

• Material composition: product prepared from ≥99 % virgin PTFE prior to pigment addition.
• Dimensional range: nominal thickness 0.025 mm to 0.51 mm (0.001–0.020 in.).
• Physical property requirements: tests and limits for properties such as apparent density, tensile strength and elongation (referenced ASTM test methods are listed in the standard).
• Referenced test methods and terminology: includes ASTM test methods and guides such as D149, D150, D257, D882, D883 and guide D6040 among others.
• Relationship to D6585: intended as a complementary, stand‑alone requirements set for pigmented PTFE products (materials with additives/pigments may vary sufficiently to require separate limits).

Typical use and users

Typical users include PTFE film/tape manufacturers, quality and materials engineers, cable and wire insulation producers, sealing and gasketing product designers, procurement/specification specialists, and testing laboratories validating compliance to ASTM property requirements. Applications commonly include thread/seal tapes, insulating tapes for electrical and industrial uses, and other pigmented PTFE films where color/additives are required.

FAQ

Q: What is this standard?

A: ASTM D7193‑17 (Reapproved 2022) is a short ASTM specification that establishes composition, dimensional limits and referenced test requirements for unsintered, pigmented polytetrafluoroethylene (PTFE) extruded film or tape. It is a companion document to the unpigmented film/tape specification (D6585).

Q: What does it cover?

A: It covers unsintered pigmented extruded PTFE film or tape produced from ≥99 % virgin PTFE (prior to pigment addition) in nominal thicknesses 0.025–0.51 mm (0.001–0.020 in.), and lists required test methods and referenced terminology and guides used to verify physical and electrical properties.

Q: Who typically uses it?

A: Manufacturers and suppliers of PTFE film and tape, product designers for sealing and insulation, cable and wire manufacturers, test laboratories, and procurement/specification engineers who need to specify or verify pigmented unsintered PTFE materials.

Q: Is it current or superseded?

A: The designation is D7193‑17 and the document was reapproved/published in 2022 (reapproval). As of the 2022 reapproval it is a current/published ASTM specification; users should check ASTM International for any later revisions or reapprovals beyond 2022.

Q: Is it part of a series?

A: It is part of the ASTM plastics/PTFE family of specifications maintained by Committee D20 (Subcommittee D20.15). It is related to and intended to complement D6585 (unsintered unpigmented PTFE film or tape) and references several ASTM test/terminology standards and ISO 13000 series documents.

Q: What are the key keywords?

A: Unsintered PTFE, pigmented PTFE, extruded film, PTFE tape, tensile, elongation, apparent density, thread seal tape, electrical insulation, ASTM D7193.
