Silicone masterbatch is a concentrated form of silicone (siloxane) polymers, acting as an additive in thermoplastics to improve their processing, surface quality, and performance. Key benefits include improved fluidity, reduced friction and wear, better mold release, and enhanced thermal stability. It is used in industries like automotive, electrical, and construction to create more efficient, durable, and high-performing plastic and rubber products.
What it is:
- A pelletized or granular additive made from high-molecular-weight silicone polymers dispersed in a compatible thermoplastic carrier.
- The active ingredient is a silicone (siloxane) resin, which provides properties like heat resistance, weather resistance, and electrical insulation.
How it Works:
- During plastic processing, the silicone additive migrates to the surface of the molten plastic, forming a protective film.
- This film lowers the friction coefficient between the plastic and the mold, preventing adhesion.
Benefits:
- Improved Processing: Increases the fluidity of the molten plastic, reducing melt viscosity and energy consumption during extrusion and injection molding.
- Enhanced Lubricity: Reduces friction and enhances wear resistance, which also aids in demolding.
- Better Surface Quality: Leads to smoother surfaces with fewer imperfections, such as white spots, and improves paint and printability.
- Increased Efficiency: Allows for higher processing speeds by preventing screw slippage and mold adhesion, boosting production output.
- Performance Enhancement: Improves heat stability, electrical insulation, and overall durability of the final product.
Applications:
- Automotive: Used in automotive interiors and other components.
- Wire and Cable: Optimizes the extrusion of cable insulation, increasing line speeds and throughput.
- Construction: Enhances the properties of construction materials.
- Electrical & Electronics: Leverages its electrical insulation properties.
- Footwear: Improves the performance and lifespan of shoe materials.
