Form:

This specification covers a glass-cloth-reinforced polytetrafluoroethylene (PTFE) resin in the form of sheet.

Application:

This sheet has been used typically for electrical, electronic, and mechanical applications requiring a composite having the high strength and nondeforming characteristics of woven glass cloth and the electrical, chemical, and heat resistance and the anti-stick and low-friction properties of PTFE resin, but usage is not limited to such applications.

Classification:

Sheet covered by this specification is classified as follows:

Type 1 - For parts requiring chemical inertness and good mechanical and electrical properties up to 260 °C (500 °F). Testing for all specified properties is required.

Type 2 - For parts requiring chemical inertness and good mechanical properties up to 260 °C (500 °F). Testing for dielectric strength and heat resistance is not required.

Unless a specific type is ordered, Type 1 shall be supplied.

Safety - Hazardous Materials:

While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
