FD-1 Copper PTFE Self Lubricating Soft Strip
FD-1 soft strip is made of PTFE with mixture of copper, FD PTFE soft strip is pressed and sintered in shape. It is of low friction coefficient, good anti-wear performance. Its tensile strength can meet the requirement of mono piston ring.
Material
Copper powder+PTFE mixture
Advantages
Appliacation
FD-1 is widely used for most of FAW Audi, Volkswagen Santana and Fukang shock absorberswhich can maintain a low friction coefficient and wear resistance for a long time.
