Application field

PTFE is widely used in mechanical equipment, electronic appliances, chemicals, construction, and sealing. It has a series of unique properties that are unmatched by other engineering plastics. PTFE plays an important role in national defense research and civil industry, especially in the field of sealing. Due to its low friction coefficient and strong self-lubricating ability, it is widely used in the manufacture of rotary shaft oil seals, seals and packings. The rotating shaft is made of PTFE and can be used at 260 ° C for a long time. This shaft seal is not only resistant to a variety of media, but also works in the absence of oil or oil. In addition, the packing and sealing gaskets made of PTFE for the transmission and sliding parts of the pump shaft, the agitating shaft and the piston rod are also particularly effective.

PTFE can also be used to make gaskets for cylinder heads of internal combustion engines, as well as bridges, pipes, steel roof trusses, support slides for large metal structures, and the like.

Good function

Teflon has many excellent functions. Such as a very low coefficient of friction, non-stick surface characteristics, a wide temperature range of -180 ° C ~ +260 ° C, excellent resistance to aging and chemical resistance. The PTFE raw material belt is made of 100% PTFE, which has a network of elongated fibers and a network of expanded structures. The PTFE raw material belt has the characteristics of good toughness, high longitudinal strength and easy deformation in the transverse direction. It is ideal for sealing on the packing and thread. However, it cannot be used in situations where high concentrations of oxygen or liquid oxygen are desired to come into contact. The Teflon tape is mainly used for packing and threaded seals. It is widely used in the sealing of pipe plugs and valve interfaces for strong oxidants, strong acids, alkalis, oxygen, gas, high temperature steam and various chemically aggressive media. The Teflon raw material belt is an auxiliary product commonly used in plumbing installations, used for pipe joints to enhance the tightness of pipe joints.
