双轴熔融拉伸可生产具有优异机械性能和上级透明度的高性能聚（PTFE）膜。独特的两步成型使PTFE粉末材料之间具有更好的粘合性，即使是107的超高分子量。这种无空隙的膜可以在熔融状态下成功地双轴拉伸。所得膜具有120MPa的高拉伸强度和8.5%雾度的高透明度。
Biaxial melt‐drawing produces a high‐performance poly(tetrafluoroethylene) (PTFE) membrane with excellent mechanical properties and superior transparency. Unique two‐step molding gives the better adhesion between the PTFE powder materials even with ultra‐high molecular weight of 107. Such void‐free film can be successfully biaxially drawn in the molten state. The resultant membrane exhibits high tensile strength of 120MPa and high transparency of 8.5% haze.
