The company can according to the user’s requirements.
The optimized combination of key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different requirements you need. .
Under the tensile force of the PTFE biaxially stretched film, the fibrils are pulled out from the PTFE resin particles. As the force increases, the length of the fibrils increases and the film becomes thinner.
When the fibril becomes no longer extensible, the force is transmitted to the middle area of the base tape in sequence, and then the middle part of the base tape is stretched.
Therefore, the film of ptfe biaxially stretched film shows a tendency of being thin on both sides and thick in the middle.
? is a high-tech enterprise focusing on the research, development and production of fluorine material film technology. The company adheres to the quality policy of “keep improving and striving for excellence” and continues to innovate in product development and production, with its unique stable performance Occupy a dominant position in the market.
