What Affects The Wear Resistance Of Engineering Plastics?

Engineering plastics have more obvious advantages than metals in some aspects, with high strength and rigidity, as well as good heat resistance and impact resistance. They can better meet the needs of modern industry and are widely used in automobiles, electronics, medical equipment and other fields.

Most engineering plastics have a high surface friction coefficient, and external lubricants are required in sliding friction occasions, which limits the application of engineering plastics in occasions where external lubricants are not allowed.

PTFE has very excellent self-lubricating properties. When blended with engineering plastics, it can prepare oil-free lubricated composite materials with low surface friction coefficient. Engineering plastics modified by PTFE are mainly used in higher-end applications.

PTFE wear-resistant lubricant used for engineering plastic modification is a PTFE ultrafine powder with a molecular weight of 30,000 to 200,000 and an average particle size of less than 30 microns. It is a special additive with the lowest friction coefficient among all friction-reducing additives. PTFE micropowder forms a lubricating film on the surface of parts during friction. It is the best wear-resistant additive in high-load applications.

PTFE micropowder not only maintains the original excellent properties of PTFE resin, but also has the same performance as high molecular weight polytetrafluoroethylene resin in terms of operating temperature range, weather resistance, chemical stability, self-lubrication, non-stickiness, etc. It also has the advantages of good dispersibility, good compatibility with other materials, no self-cohesion, no electrostatic effect, etc. It is widely used in modified engineering plastics, rubber, coatings, lubricating grease, diamond grinding wheels, brake pads, phenolic resin and other substrates to improve the lubricity, wear resistance, non-stickiness, etc. of the substrate.

Features of PTFE micropowder for modified engineering plastics of Nanjing Tianshi:

1. Better self-lubrication and wear resistance.

2. Higher demoulding performance.

3. Faster processing speed.

Nanjing Tianshi has established an engineering plastics application laboratory equipped with more than 10 testing equipment and instruments to test the key indicators of the product (particle size, temperature resistance, fluidity, melting point, whiteness). Tianshi can also provide wear resistance test evaluation tests for downstream manufacturers, including: plastic performance test, tensile strength, bending strength, flame retardant performance, etc.
