1. Silicone powder
Silicone powder we also can say siloxane powder is a widely used additive in the plastic and rubber industries. It can provide various performance improvements, especially in the lubrication of engineering plastics. Here are some basic introductions to silicone powder and its advantages in lubricating engineering plastics.
What’s more, silicone powder is a form of polysiloxane with a very stable chemical structure, therefore it has good temperature resistance, chemical resistance, and UV resistance.
Thirdly, it usually exists in the form of micrometer or nanometer sized powder and is easily dispersed in plastics and other materials, and then powder is widely used in plastics, rubber, coatings, adhesives, and sealants to improve processing performance and physical properties of final products.
2. Advantages of silicone powder in lubricating engineering plastics
2.1 Powder can be used as an internal lubricant to reduce the friction between polymer molecules, thereby improving the material’s fluidity and making processing easier.
2.2 Due to the lubricating effect of powder, it can reduce the wear of equipment components during the processing and extend the service life of the equipment.
2.3 Powder helps provide a smoother surface and reduces surface defects such as orange peel and scratches in the product.
2.4 Enhanced demolding ability: In injection molding, silicone powder can be used as a demolding agent to reduce adhesion between the molded part and the mold, thereby reducing demolding force and improving production efficiency.
2.5 Powder has excellent thermal stability, which can maintain performance during high-temperature processing and help improve the processing temperature range of engineering plastics.
2.6 Compared with other types of lubricants, silicone powder is less likely to precipitate or migrate to the material surface during long-term use, thereby maintaining the performance and appearance of the product.
