PTFE Roll Sheet (Polytetrafluoroethylene Roll Sheet) is a roll sheet made of polytetrafluoroethylene (PTFE) resin as the base material through calendering or extrusion process. PTFE is a polymer material synthesized by free radical polymerization of tetrafluoroethylene (TFE, CF₂=CF₂) monomer under the action of initiator (such as ammonium persulfate). Its molecular chain is composed of repeated -CF₂-CF₂- units. It has extremely high chemical inertness, low friction coefficient and excellent temperature resistance, and is known as the "King of Plastics".

Application fields

Chemical industry and energy

Chemical equipment seals: PTFE roll sheets are used for reactor gaskets and pipeline flange seals, which are resistant to strong acids and alkalis and have no swelling;

Proton exchange membrane substrate for fuel cells: Ultra-thin PTFE sheets are used as proton exchange membrane carriers after sulfonation modification, which have both high chemical stability and proton conductivity.

PTFE Sheet

Electronics and semiconductors

High-voltage cable insulation layer: PTFE roll sheets are used for the insulation shielding layer of ultra-high voltage cables, with a voltage resistance of ≥60 kV/mm and low dielectric loss;

Semiconductor manufacturing carrier tray: Ultra-high purity PTFE sheets are used for carrier trays in silicon wafer etching processes, which are resistant to plasma corrosion.

Aerospace and defense

Aircraft fuel system seals: PTFE roll sheets are used for aircraft engine fuel pipeline sealing, which are resistant to aviation kerosene and high and low temperature;

Missile radome: Low dielectric loss PTFE sheets are used for missile radar radomes to reduce signal attenuation.

Buildings and civil facilities

Building waterproofing membrane: PTFE roll sheet is used for large roof waterproofing, UV-resistant and self-cleaning;

High-end kitchenware non-stick coating substrate: Micro-powder-modified PTFE sheet is used as non-stick pan coating substrate, with a friction coefficient as low as 0.04.
