FD-1 is made of PTFE as the main raw material, filled with copper powder and other wear-resistant materials, pressed and sintered by a mold. It has good wear resistance and low friction factor. Its tensile strength can meet the use conditions of single piston ring. The product can be used normally in oil and oilless lubrication conditions, and is the ideal choice of car shock absorbers and piston rings.Currently, most of the shock absorbers of FAW Audi, Volkswagen Santana, and Gaokang use this product, which can maintain a low Friction Coef. and wear resistance for a long time.
