The forming process of ptfe film is mostly based on the double stretching or stretching processing method abroad.
PTFE can be stretched at room temperature to 327°C, that is, the stretching below the melting point is performed in a high elastic state.
Stretching at low temperatures will cause the film to break, making stretching impossible.
When the temperature is higher than 327°C, the crystalline state between polytetrafluoroethylene molecules changes to amorphous, and the network structure cannot be obtained well, so the general stretching temperature is between 40°C and 327°C.
Suzhou New Material Technology Co., Ltd. specializes in the production and sales of PTFE films and various types of film-coated filter material products.
The company adheres to the quality policy of “strive for excellence and strive for excellence”, continues to innovate in product development and production, and occupies a dominant position in the market with its unique stable performance.
