Rubber protective additives

In nature and use of the environment in particular, polyurethane and other polymer materials, the thermal oxidative degradation occurs in the light, heat, oxygen, water, and the presence of micro-organisms, hydrolysis, photodegradation and microbial degradation, which will make the strength of the polymer reduce until lose value. In order to inhibit the degradation, extend the life of the material, we must add protective additives, such as antioxidants, light stabilizers, anti-hydrolysis agent and so on.
