Analysis of composition and function of weather-resistant masterbatch!

weather-resistant masterbatch is a kind of plastic additive with special properties, mainly used to improve the durability and stability of plastic products in outdoor environment. The following is a detailed description of the weather-resistant masterbatch:

Composition and function of weather-resistant masterbatch

Uv absorbent:

This is one of the key components in weather-resistant masterbatch. It can strongly absorb ultraviolet light and convert its energy into harmless heat energy or lower energy radiation, thereby preventing ultraviolet light from causing damage to the molecular structure of plastic products.

For example, benzophenone and benzotriazole ultraviolet absorbers can effectively absorb ultraviolet light in the range of 290-400 nanometers, protecting plastic products from ultraviolet light erosion.

Light stabilizer:

The main function is to capture and eliminate the free radicals produced by plastic products when they are irradiated by ultraviolet light, and prevent the chain reaction caused by free radicals, thus delaying the aging process of plastic products.

Hindered amine light stabilizer (HALS) is a commonly used light stabilizer, which has the advantages of high efficiency, low toxicity, heat resistance, etc. It can form a protective film on the surface of plastic products and effectively inhibit the photooxidation reaction.

Antioxidants:

It can prevent the oxidative degradation of plastic products under high temperature, oxygen and other environmental factors. Antioxidants can react with oxygen in the air to form stable compounds that protect the molecular structure of plastic products from oxidation.

For example, phenolic antioxidants and phosphite antioxidants, which can effectively inhibit oxidation reactions during the processing and use of plastic products.
