The Girts of Acid washed black silicon carbide for SiC Expoxy are black silicon carbide #320, #90, #60, and #12. SiC Epoxy is a new type of polymer composite material. It has characteristics including high strength, low density, high thermal conductivity, high-temperature corrosion resistance, fire resistance, non-conductivity, and easy processing. Epoxy resin silicon carbide is a modified resin material with the addition of black silicon carbide and other additives. The superior performance comes from the raw material SiC grits.
Silicon carbide(Carborundum) is a ceramic wear-resistant material with high hardness, high melting point, and excellent wear resistance. It can improve the performance of Epoxy in the following aspects:
>> High-temperature performance.
The refractory temperature of silicon carbide filler is 1800 ° C. Moreover, it maintains very stable physical and chemical properties within 1400 ° C. That enables SiC-Epoxy to maintain good stability and strength in high-temperature environments.
>>Lightweight.
The specific gravity of silicon carbide is 3.2g/cm3. The acid-washed black silicon carbide # 320 has a bulk density of only 1.3-1.4g/cm3. The low density makes the Silicon carbide Epoxy much lower than the metal material with the same strength.
>> Wear resistance.
Silicon carbide filler has excellent wear resistance characteristics, making the SiC epoxy have excellent wear resistance and scratch resistance. The modified epoxy resin added with silicon carbide powder has good compactness and improves the wear resistance of the material.
>>Electrical insulation.
Silicon carbide is an electrical insulation material at room temperature. It makes Epoxy suitable for electronic insulation applications.
>>Volume stability.
Silicon carbide materials have a very low thermal expansion rate. The thermal expansion coefficient of black silicon carbide at room temperature is 6.7×10-6. That gives the Silicon carbide epoxy high thermal stability. After mineral casting into components, it can maintain high shape stability and mechanical accuracy.
>>Strength and rigidity.
Silicon carbide fillers can enhance the mechanical properties of SiC epoxy, increasing their strength and rigidity. After casting, SiC epoxy resin composite materials can also maintain high compressive strength and flexural strength.
>>High thermal conductivity.
The thermal conductivity of black silicon carbide at room temperature is 70-130 W/M · K. And the thermal conductivity of the synthesized modified epoxy resin is 1.9-2.5 W/M · K. Thus, it can effectively transmit the heat generated by the equipment. The typical application is producing epoxy thermal conductive adhesive.
>>Flowability.
Black silicon carbide powder # 320 is a powder that has been washed with acid and alkali and purified water. Black silicon carbide particles have high flowability. This is beneficial for bonding with epoxy resin, maintaining good fluidity, and facilitating storage in liquid or semi-solid form.
Silicon carbide Epoxy is widely used in high-temperature sealing, wear-resistant components, electronic insulation materials, aerospace, and other fields to meet high-performance and special environmental requirements.
