GC2000# Green Silicon Carbide Powder as a Thermally Conductive Filler for PVC
GC2000# green silicon carbide micro powder is a powder material with high thermal conductivity, high refractory temperature, low coefficient of thermal expansion, and high-temperature performance. Its core advantages as a thermally conductive filler for PVC are: good thermal conductivity, high hardness, chemical stability, fine particle size, and good dispersibility, making it ideal for both soft and rigid PVC thermally conductive products.
1. Improved Thermal Conductivity
– Silicon carbide powder possesses high thermal conductivity not found in other non-metallic materials, and GC2000# fine powder significantly improves thermal conductivity.
– Can be used in: thermally conductive PVC hoses, sheets, cable materials, thermally conductive seals, heat dissipation sleeves, etc.
2. Improved Heat Resistance and Thermal Stability
– Accelerates heat dissipation and reduces localized heat accumulation.
– Increases the long-term service temperature and lifespan of products.
3. Enhanced Mechanical Properties
– Improves hardness, wear resistance, and tensile strength.
– Reduced creep and deformation, suitable for applications requiring both wear resistance and thermal conductivity.
4. Improved dimensional stability and low shrinkage
– Inorganic fillers reduce PVC cooling shrinkage, resulting in more stable product dimensions.
5. Good chemical stability and corrosion resistance
– Green silicon carbide is resistant to acids and alkalis and does not react with PVC. Adding it to PVC materials can improve the corrosion resistance of the finished product.
– Minimal impact on electrical properties, suitable for insulation and thermal conductivity applications.
6. Unique advantages of Green Silicon Carbide Powder 2000#
– High silicon carbide purity: GC 2000# micro powder has a silicon carbide content of 98.5-99.5%, with few impurities and high purity.
– Concentrated particle size range, high uniformity, good dispersibility, and resistance to agglomeration.
– Relatively mild impact on surface finish, feel, and processing flowability.
– Suitable for PVC products with high filler content, high thermal conductivity, and good appearance requirements.
