New expanded PTFE sealing materials - Xinhua Xu

 Xinhua Xu rubber products expanded polytetrafluoroethylene (EPTFE) is currently a unique new sealing materials, science and technology is a further extension of polytetrafluoroethylene, a sealing material because it is made of pure PTFE and specially processed form, The processing procedure shown in Fig. Thus inherits the excellent characteristics of PTFE, while giving the polytetrafluoroethylene as bright cotton-like flexibility, a high degree of compressibility, creep resistance, self-lubricating, low friction coefficient and high tensile strength. Xinhua Xu rubber products it changes the ordinary PTFE gasket sealing material is present perfect, poor recovery, thermal expansion coefficient, creep after prone to failure and other shortcomings. Thus a good solution to the traditional dynamic seal will not solve the problem. In recent years, with the conversion of foreign technology in the country, expanded polytetrafluoroethylene material as a new sealing material, have been actively active on the world stage, in the chemical, petrochemical, oil, bio-chemical, aerospace, pharmaceuticals, machinery, catering and other industries flourish, creating a new world of modern seal.

Xinhua Xu rubber products expanded polytetrafluoroethylene (Expanded PTFE) is a PTFE dispersion resin raw material membrane through a unique manufacturing process from the drawing containing a large number of pores, high toughness of low-density material. Which not only preserves the unique properties of PTFE, namely, good chemical resistance, low friction coefficient, but also expanded the application temperature range, tensile strength increased 2.5 times, the density becomes a factor of 10.

This film of material per square centimeter of the 1.4 billion small holes, these holes 20,000 times smaller than water molecules, 700 times larger than the vapor molecules, while irregular arrangement, the material consists of numerous fine soft tough homogeneous multidirectional fibers, a unique high sealing fibrous tissue, compression of the fibers will be entangled with each other, the organization becomes even closer, under severe corrosive environment and high temperature can maintain an excellent sealing state.

Xinhua Xu rubber products expanded polytetrafluoroethylene (EPTFE) is currently a unique new sealing materials, science and technology is a further extension of polytetrafluoroethylene. Because it is a pure PTFE sealing material specially processed to form, changing the ordinary PTFE sealing material is present perfect, poor recovery, thermal expansion coefficient, prone to failure after creep and other shortcomings.

With the conversion of foreign technology in the country, expanded polytetrafluoroethylene material as a new sealing material, have been actively active on the world stage, in the chemical, petrochemical, oil, bio-chemical, aerospace, pharmaceuticals, machinery, food, etc. industry flourish, creating a new world of modern seal.
