Application:

High wear resistance self lubricating casting type oily nylon is a new kind of engineering plastic which belongs to polyamide polymers. The comprehensive performance and utility ranks No. 1 among the 5 kinds of engineering plastics due to the following characters: self-lubricating, high wear resistance, shock resistance, noise reduction. It can widely replace non-ferrous alloys such as Tin-Zinc-Copper alloys, aluminum alloys, zinc-based alloys, SS, etc, for making kinds of mechanical structure parts, shock resistance parts, transmission parts, etc. specially suitable for making bearings bush, sliding bearings, lining baskets, gears, sliding blocks, gear wheels, turbines, guiding sleeves,etc, which is used in industries such as mining, metallic, rolling mills, chemical rubber, textile machine manufactures.

Propertie:

1.  This high wear resistance self lubricating oily nylon is one kind of polymer materials with average molecular No. is more than one hundred thousand, which is 5 times than normal nylon material. The comprehensive performance is superior to other thermal engineering plastics. 

2. The density is 1.2 at 25℃, the weight is only 1/8 of the tin-zinc-copper alloy parts in same volume. It is easy installation and reduction the cost. 

3. High mechanical strength and impact resistance. The simply supported beam notch impact strength is up to 6KJ/squre, which is 4 times of tin-zinc-copper alloys. 

4.The fine mineral oil additives are added in the polymerization process to increase self-lubricating and reduce friction coefficient. The friction coefficient is 1/3 of ordinary nylons. Is 1/2 of zinc-copper alloys. The wear weight after  milling with 45# steel for 2 hours is 2.5*10-3, which is 1/100 of zinc-copper alloys. 

5. The viscose softening point is 212℃, heat deformation temperature is 200℃, highest continuous heat-resistance  temperature is 170℃.

6. insulated, oxidation resistance, corrosion resistance, aging resisting.
