Nylon 6 and nylon 66 are now playing an increasingly important role in the production of auto parts, thus competing with the original materials - metal and thermosetting plastics.

The predominance of nylon in auto parts is mainly related to its excellent properties: high temperature resistance, oil resistance, chemical resistance, high tensile strength and modulus, relatively low density and low production cost, good surface properties. , the possibility of cooperation between components.

Nylon is commonly used in the following automotive accessories: hood, rocker cover, cooling heater and fuel tank. The nylon resins used in these aspects are reinforced with 20-40% glass or other mineral fibers to increase strength. It is also possible to use a special chemical method to treat the nylon resin to weaken the disadvantages such as hydrolysis and oxidation, and to enhance the advantages of heat resistance.

The appearance factor of the hood is very important, and nylon can provide a good surface for the product, so nylon is very suitable for this application. At the same time, nylon can also obtain colored molded parts, thus avoiding expensive painting steps.

Some modified nylons that are very suitable for hood manufacturing have already been applied.
