Wear resistance is an important index to determine the application field and service life of plastics. In order to reduce the friction and wear of plastic, you can choose to add lubricating oil or wear-resistant packing. Lubricating oil has many disadvantages. For a long time, the oil will age, and it needs to be maintained regularly, and it is easy to gather dust and debris, and pollute internal parts. How to improve the wear resistance of plastics?

1、PTFE

PTFE micro powder can be applied to engineering plastics, coatings, ink, paint, lubricating oil, film, rubber, etc., can enhance the performance of the main material, such as:

1.Resistance to abrasion, friction and scratch；

2.Easy decontamination characteristics；

3.Adhesion resistance；

4.Lubrication performance (for modification of engineering plastics)；

5.Resistance to friction and wear。

2、Molybdenum disulfide

Molybdenum disulfide (MoS2) is a black metallic luster, touch the greasy powder, Molybdenum disulfide is an important solid lubricant, especially suitable for high temperature and high pressure, known as the "king of senior solid lubricating oil". In the field of engineering plastics, it is mainly used as a wear-resisting additive for nylon plastics.

Compared with pure resin, the rigidity, hardness and dimensional stability of nylon 66/ molybdenum dioxide (gray-black) are improved, but the impact strength is decreased. The grain formation effect of molybdenum disulfide improves the crystal structure, so that the bearing capacity and wear resistance of the material are improved. Widely used in gears, bearings, sealing rings, sliders, etc.

3、Graphite

The unique chemical structure of graphite allows the graphite molecules to slide easily over each other with very little friction. This wear resistance property is especially important in the presence of water. This property makes graphite an ideal wear resistant additive for many applications in water, such as water shell, impeller, and Valueseals.
