How to improve TPE anti-scratch
Improving TPE anti-scratch by silicone masterbatch is mainly achieved through the following aspects:
1. The mechanism of action of silicone masterbatch
Silicone masterbatch is a functional masterbatch that uses various thermoplastic materials as carriers and organic polydimethylsiloxane as active ingredients. It can play multiple roles in plastics such as TPE, including improving processing performance and enhancing surface properties.
Specifically, silicone masterbatch can:
Mejora de la fluidez:
Silicone masterbatch can improve the flowability of TPE in a molten state, making it easier for the material to flow and fill the mold during processing, thereby reducing defects such as bubbles and shrinkage caused by poor flow.
Mejorar el rendimiento de la superficie:
Silicone masterbatch can significantly reduce the surface friction coefficient of TPE, improve the smoothness and wear resistance of the surface. This improvement enables TPE products to more effectively resist scratches when subjected to external forces.
Enhanced lubricity:
The lubricity of silicone masterbatch can reduce the friction and wear of TPE during processing, thereby protecting equipment and molds, and also helping to improve the demolding and surface smoothness of products.
2.Specific methods to increase TPE anti-scratch
Select suitable silicone masterbatch:
Choose the appropriate silicone masterbatch based on the specific type and processing requirements of TPE. Different silicone masterbatch may have different compositions, contents, and properties, so the selection needs to be based on the actual situation.
Determining the addition ratio:
The addition ratio of silicone masterbatch has a significant impact on the scratch resistance of TPE. Generally speaking, the addition ratio is more common between 1% and 5%. The specific proportion needs to be adjusted based on experimental and practical application effects.
Uniform mixing:
Mix silicone masterbatch thoroughly with TPE raw materials to ensure even distribution of silicone masterbatch in TPE. This can be achieved through mechanical mixing, melt blending, and other methods.
Optimize processing technology:
During the processing, pay attention to controlling parameters such as temperature, pressure, and speed to ensure that TPE can fully melt and flow uniformly. Meanwhile, it is important to avoid performance degradation caused by excessive or insufficient processing.
