Whether it is wear resistance, high temperature resistance, etc., the automobile brake hard pipe will be better than POM in all aspects, the quality is relatively good, and the price is not expensive. As a large amount, it is widely used in machinery, automobiles, electrical appliances, textile equipment, chemical industry equipment, aviation, metallurgy and other fields. It has become an indispensable structural material in various industries, and its main characteristics are as follows:

1. Excellent mechanical properties, high toughness.

2. Good self-lubrication and friction resistance. It has good self-lubricating property and small friction coefficient, so it has a long service life as a transmission part.

3. Excellent heat resistance. High crystallinity nylon such as nylon 46 is very high and can be used for a long time at 150 °C. After being reinforced by glass fiber, its heat distortion temperature reaches above 250℃.

4. Excellent electrical insulating properties. It is an excellent electrical and electrical insulating material.

5. Excellent weather resistance.

6. Absorbent. High water absorption, saturated water can reach more than 3%. To a certain extent, it affects the dimensional stability of the product.
