    1. Detailed information

    SF - 1 PI is based on low carbon steel substrate without oil bearing, spherical bronze powder on the surface, and then on the surface covered with a layer of polyimide (PI) of modified PTFE material, plate after rolling forming, made into bushing forms, etc. Since polyimide is a kind of mechanical strength of organic polymer materials, can withstand the high intensity of alternating load, good fatigue resistance performance, and not bibulous, corrosion resistance, so the product is very suitable for automotive tension belt up high load, such as change the motion of the frequent occasion to use; Polyimide materials and thermal stability is good, can use for a long time under temperature of 300 ℃, so the product can also be used for electronic oven and other high temperature occasion.
