Applications of Green Silicon Carbide (GC) Micropowder as a Filler in Fluoropolymer Products
Green Silicon Carbide (GC) is characterized by high hardness, high strength, strong corrosion resistance, excellent chemical and high-temperature stability, good self-sharpening properties, high thermal conductivity, and a low coefficient of thermal expansion.
1. Green Silicon Carbide Micropowder as a Filler for Modified PTFE (Polytetrafluoroethylene)
Used in components for semiconductor plasma chambers, wafer carriers, insulating rings, valve seats, and sliding seals. It enhances resistance to plasma erosion and wear, improves thermal conductivity and creep resistance, and reduces outgassing/contamination under plasma exposure. Specific forms include molded PTFE, extruded PTFE, and PTFE composite sheets/rods.
2. Green Silicon Carbide Micropowder as a Filler for FKM (Fluororubber)
Incorporated into O-rings and gaskets used in semiconductor manufacturing, lithium-ion battery production, and chemical processing equipment. It improves wear resistance, thermal conductivity, arc resistance, and resistance to chemical media.
3. FFKM (Perfluoroelastomer)
Used in seals for high-end semiconductor equipment. The addition of a small amount of Green Silicon Carbide (GC) micropowder provides a balance of plasma resistance and wear resistance, resulting in a high-value formulation.
4. Green Silicon Carbide Micropowder as a Filler for Modified PFA (Perfluoroalkoxy Alkane)
Used in linings for semiconductor fluid piping, spray nozzles, and wafer carriers. It is suitable for applications requiring transparency or translucency alongside plasma resistance; the addition level is typically low.
5. Green Silicon Carbide Micropowder as a Filler for Fluorocarbon Coatings (Solvent-based, Water-based, or Powder Coatings)
Used in anti-corrosive and wear-resistant coatings, non-stick (Teflon-type) coatings, and protective equipment coatings. It enhances hardness, resistance to wear and erosion, and provides superior high-temperature and corrosion resistance.
6. Green Silicon Carbide (GC) micropowder as a filler for modified fluoroplastics (such as ETFE and PVDF)
Used in structural components for lithium batteries, photovoltaics, and chemical anti-corrosion applications, primarily to enhance wear resistance and thermal conductivity.
7. Fluorine-based greases and pastes
Used in high-temperature, anti-corrosive lubrication systems, where Green Silicon Carbide (GC) micropowder serves as a wear-resistant solid filler.
In summary, Green Silicon Carbide micropowder is primarily used as a filler in materials such as PTFE, FKM (fluororubber), FFKM (perfluoroelastomer), modified PFA, and wear-resistant fluorocarbon coatings.
