IMPROVED COMPOSITION OF EXPANDED POLYTETRAFLUOROETHYLENE AND SIMILAR POLYMERS AND METHOD FOR PRODUCING SAME
摘要
The present invention provides improved compositions of expanded polytetrafluoroethylene (PTFE) and similar polymers and methods for forming and using such compositions. In its preferred embodiment, the present invention employs a mixture of PTFE and expandable thermoplastic microspheres. Through application of an energy source to the mixture, a coherent three dimensional expansion of PTFE can be achieved. The expanded mixture has many of the same beneficial properties of mechanically expanded PTFE and numerous properties previously unavailable with expanded PTFE products.
