PFA film is a hot melt extrusion cast film made of PFA resin (copolymer of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene). TCI's PFA film provides all the excellent properties of fluorine element films, such as chemical resistance, stress tear resistance and excellent electrical properties under long-term working at 260°C.
PFA film can be thermally welded, thermoformed, and can be combined with a variety of materials, and is often used for excellent hot melt materials
PFA film is chemically inert and resistant to almost all chemicals. It is very suitable for the complex requirements of high temperature and chemical resistance, such as chemical pumps, tank linings, shrink tubes, rupture discs and seals, etc.
PFA film has excellent electrical properties in a wide temperature range, and can be used in high-frequency copper clad laminates, wire and cable insulation, etc.
(1) PFA PG series
It is made of 100% high-purity PFA resin, with MFI value between 5-2.5
(2) PFA WG series
It will save 15%-20% of the cost compared with the PG series film, and has the same physical properties, mechanical properties and thermoforming properties as the PG series
Very suitable for heating sealing, welding and other hot melt adhesive applications that do not have high requirements on appearance
The most high temperature and low temperature resistance among fusible fluoropolymers
Long-term stable working temperature from -254°C to 260°C
Melting temperature range from 302°C to 310°C
Chemically inert to almost all chemicals and solvents
Maintain excellent electrical performance in a wide frequency and temperature range
High dielectric strength, exceeding 6500V/25μm (260kV/mm)
Excellent optical transmittance and transparency
Freely mix other plastics, additives and other additives
Thickness ranges from 12μm to 250μm
Standard width: the widest to 1524mm
Thickness is greater than 50μm, width can reach 1575mm
Can be cut into specified width as required
Bondable surface (plasma treatment and chemical etching treatment)
