Product Description

Elongation @ Break ≥ 200% OEM PTFE Banded Piston Applied In Car Front Shock Absorber



A shock absorber includes a cylinder, a piston, a piston rod and other components.


The production cost of shock absorber piston using PTFE and filled with modified material could decrease


by 20%, attain the desired results of filling the modified material and greatly improve the service


performance of the piston.


Material to be used for motorcycle and automotive shock absorber piston ring must meet the working


mode requirement in order to realize long working life. Banding material used by us can meet this






Physical performance for shock piston

We are engaged in developing and manufacturing different kinds of shock absorber piston absorber pistons, they have advantages of low friction, good seal etc. We have test machines such as hardness meter (D), projector, analysis balance, friction wear testing machine, blow-off testing machines, fatigue testing machine and so on. Other items that we can't test in our company, we will send standard block samples to Shanghai Plastics Research Institute, so that we can assure the consistency of the raw material.


We have set up good cooperative relationship with some big shock absorber factories home and abroad. Our mass production piston types are:ø25,ø27,ø30,ø31,ø32,ø35,ø36,ø40,ø45.
