Study on Scratch Resistance of Silicone Masterbatch

As the application of plastic modified materials becomes more and more extensive, higher requirements are imposed on various properties of plastic parts, especially in some frequently used occasions, The surface of plastic products is required to have high scratch resistance. Therefore, more and more attention has been paid to the research on the use of anti-friction materials on plastic surfaces, and silicone materials have received more attention due to their superior properties. At present, the common silicone masterbatch, including imported products, may cause the screw to slip during mixing, which is not conducive to the dispersion of the filler.The common silicone masterbatch always migrates to storage due to the low surface tension specific to silicone Trends in plastic surfaces. In some imported silicone products, in order to slow down their migration speed, the molar mass can only be increased, but because the surface tension of silicon is only 22, far lower than carbon compounds, so its migration always exists, and its wear resistance is only Limited to the surface, and not durable. However, the addition of silicone materials with carbon chain ends can be stored for a long time without migrating to the plastic surface and causing fogging on the surface of the material.
