Plastic products are prone to scratches, affecting beauty and performance. In order to improve the scratch resistance of plastics, some special additives are usually added. Here are some common anti-scratch additives:

Silicone oil and silane coupling agents: Silicone oil can be used as an external lubricant to reduce the friction coefficient of the plastic surface, so that it is not easy to leave scratches when friction contact. The silane coupling agent can improve the hydrolysis resistance and chemical corrosion resistance of the polymer material, and also enhance the scratch resistance of the material.

Nano fillers: nano grade filling materials such as nano silicon oxide, nano alumina, nano zinc oxide, etc., can significantly improve the hardness and wear resistance of plastic materials, thereby improving its scratch resistance.

Polymer modifiers: Some polymer modifiers such as elastomers, thermoplastic elastomers (TPE), thermoplastic polyurethanes (TPU), etc., can significantly improve scratch resistance when mixed with plastic substrates.

Surface coating: The application of special coating materials, such as fluoropolymer, polyurethane coating, etc., can form a protective layer to avoid direct contact with and scratching the base material.

Anti-scratch AIDS: There are also a number of specially designed anti-scratch AIDS on the market, which disperse evenly in the plastic and provide long-lasting anti-scratch effects.

However, it is worth noting that the choice of additives needs to consider the type of plastic, the compatibility of additives, the application requirements of the final product and other aspects of the factors. In addition, the amount of additives added also needs to be properly controlled to ensure the comprehensive performance of plastic products.
