In the mid-1970s, the American Gore Company successfully developed expanded PTFE microporous films using biaxial stretching technology. After that, Japan made great progress in research in this area and applied for a number of patents.
my country began to develop PTFE stretch film after the 1970s, but it has been stuck in the uniaxial stretching process for a long time. Since the 1990s, some units have developed and produced biaxially stretched PTFE films.
It is a high-tech enterprise specializing in the research and development, production and sales of polytetrafluoroethylene microporous membranes. It has advanced ptfe membrane production lines, coating and composite production lines, which are at the domestic advanced level.
