1. Introduction of silicone masterbatch
Silicone masterbatch is a widely used additive in plastic processing, which has multiple functions and advantages. Firstly, silicone masterbatch can effectively improve the processing performance of plastics, including improving the fluidity of the molten state, enhancing the filling ability, reducing torque and pressure, thereby reducing energy consumption and minimizing the problem of melt fracture.
In addition, silicone masterbatch can significantly reduce the friction coefficient on the surface of plastic products, improve smoothness, enhance wear and scratch resistance, and increase the surface glossiness and tactile sensation of the product.
Silicone masterbatch has a wide range of applications, suitable for various thermoplastic materials such as PP, PE, EVA, ABS, PA, PC, etc. It also plays a role in modified plastics, halogen-free flame-retardant cable materials, high-end shoe soles, plastic insulation seals, large injection molded parts and other products.
In specific application cases, silicone mb can serve as a flame retardant synergist, improving the flame retardant performance of materials while maintaining environmental standards and meeting environmental requirements in regions such as the European Union.
In the development and application research of silicone masterbatch for plastic processing, researchers have found that the use of silicone masterbatch can improve the processing performance of high-density polyethylene composite materials, and the comprehensive performance of the composite material is optimal when the addition amount is 0.5%.
In addition, silicone masterbatch can also be used as a lubricant and opening agent for thin film processing such as CPP and CPE, providing low surface friction coefficient and good transparency, as well as high temperature resistance and non migration characteristics.
The performance characteristics of silicone additives include improving processing performance, reducing surface friction coefficient, enhancing wear resistance, etc.
It also has good stability and non migration, and is suitable for the production of various plastic products. The application of silicone mb can significantly improve the performance and service life of products in the fields of automotive interior, wire and cable, shoe materials, etc.
2. Mechanism of silicone mastebatch
The mechanism by which silicone masterbatch improves the fluidity of molten state in plastic processing mainly includes the following aspects:
1. * * Reduce interface adhesion and friction * *: Silicone masterbatch, as a lubricant, can reduce the interface adhesion and friction between plastic melt and processing equipment, thereby reducing torque and pressure and improving melt flowability.
2. * * Improving filler dispersion * *: Silicone additive helps improve the dispersion of mineral and inorganic fillers in plastic melts, reduce energy consumption in extrusion injection molding, and improve production efficiency.
3. * * Improve melting rate and deformability * *: Silicone masterbatch can increase the melting rate of plastics, reduce viscosity, improve plasticizing effect, prevent melt cracking, and thus improve the fluidity of the melt.
4. * * Reduce melt fracture and die accumulation * *: Silicone masterbatch helps maintain consistency in melt flowability by reducing melt fracture and die accumulation during processing.
5. * * Improve mold filling ability * *: Silicone mb can enhance the mold filling ability of plastic melt, making it easier for the melt to fill the mold, thereby improving the quality and production efficiency of the product.
6. * * Solid particles are easy to disperse and have no migration * *: Silicone masterbatch, as a solid particle, is easy to disperse in the resin without migration, which helps maintain the consistency and stability of plastic products.
7. * * Special Preparation Process * *: Silicon Treasure adopts a special preparation process to achieve stable preparation of different ultra-high molecular weight silicones. This structural feature helps to improve the lubrication performance of silicone mb in plastic processing.
Through these mechanisms of action, silicone masterbatch can effectively improve the flowability of plastics in a molten state, thereby enhancing the performance of plastic processing and final products.
