Problems solved by technology

Some people add ordinary inorganic fillers to the material. Large inorganic filler particles are dispersed on the surface of the product, which can greatly reduce the gloss of the material, but it also has a greater impact on the mechanical properties of the material.
Some people add an incompatible rubber phase to the material to form diffuse reflection on the surface of the workpiece, which can also properly reduce the gloss of the material, but the degree of reduction is very limited, and it cannot achieve the high matteness of the current automotive interior materials Require
Some people add pre-crosslinked high-molecular-weight AS to the material, which can achieve a better matte effect on the glossy surface of the part. , the two interfere with each other, resulting in uneven matte effect, and in severe cases, there will be bright spots
Moreover, this pre-crosslinked high-molecular-weight AS has poor compatibility with the base material, and it is difficult to disperse it evenly in the base material, which will also affect the mechanical properties and heat resistance of the material, as well as the matte surface of the product.
