The influence of research and development of ultra-high thermal conductivity and ultra-flexible thermal gasket products on the market

Ultra-high thermal conductivity and ultra-flexible thermal pads are a series of products with a thermal conductivity greater than 12W/m·K and excellent compliance, as shown in Table 1. This series of products is designed to solve the problem of heat dissipation between the heating device and the heat sink of highly integrated electronic equipment with high heat flux density. The ultra-flexibility of this series of materials can quickly fill irregular rough surfaces, ensure excellent interfacial wettability and interface adaptability, effectively eliminate the thermal resistance generated by the air between the interfaces, reduce the thermal resistance of the interfacial contact, form a good heat transfer bridge, and facilitate the heat export of heating devices.

Exploration and research report of NR molecular chains

On the one hand, the chemical stability of EPDM is much better than that of NR. This is because in the sulfurization process, there will be many double bonds in the molecular chain of NR that are not used by sulfur cross-linking, which is susceptible to the action of external factors and leads to the breakage of chemical bonds, which is also the main reason for the poor ozone resistance and weather resistance of NR. On the other hand, vulcanization of EPDM is more difficult and slower than that of NR, and the promotion dose required for vulcanization of EPDM is also higher than that of NR.

Ethylene propylene rubber series in the market application

Ethylene propylene diene monomer (EP(D)M; In China, EPR is a copolymer rubber synthesized based on ethylene and propylene, and the molecular chain of copolymer rubber is divided into dibasic ethylene propylene and EPDM rubber according to the composition of monomer units. Ethylene propylene (EPDM) is a copolymer of ethylene and propylene, expressed as EPM; EPDM is a copolymer of ethylene, propylene and a small amount of unconjugated diene third monomer, expressed as EPDM, which is collectively referred to as EPDM (D)M.
