One-component thermal conductive silicone rubber belongs to room temperature curable silicone rubber. One-component electronic thermal conductive silicone rubber is refined from imported silicone as the main raw material and other ingredients. It is crosslinked by releasing low molecular weight through condensation reaction with moisture in air, and vulcanized into high-performance monomers. After fully cured, it has excellent resistance to high and low temperature changes, and will not reduce heat dissipation due to contact gap after fixing components.
Single-component thermal conductive silica gel has excellent thermal conductivity and heat dissipation performance, as well as excellent electrical properties, aging resistance, thermal and cold alternation resistance, moisture-proof and non-swelling, electrical insulation, power degradation rate, shock-proof, water-proof, vibration absorption and stability, which increase the safety factor of electronic products in the use process. It has excellent bonding strength for electronic components, PVC, plastics and so on. It also has excellent sealing and thermal conductivity.
This product is easy to operate, can be manually sized or mechanically sized, no leakage, meet a variety of working environments and working places, with easy and convenient sizing performance. One-component thermal conductive silica gel is a non-toxic, non-polluting product, more safe and environmental protection, has passed the EU RoHS standard.
Two-component thermal conductive silica gel is used as a heat transfer medium for cooling electronic devices. It can be solidified into flexible elastomers in situ and does not produce stress on electronic components. After solidification, the heat resistance is reduced by close adherence to the contact surface, which is more conducive to the heat transfer between the heat source and its surrounding fins, motherboard, metal and external ones.
Dual-component thermal conductive silica gel has the advantages of high thermal conductivity, good insulation and easy to use. It can be widely used in the packaging of integrated circuits, integrated chips, converters, other power modules, semiconductors, relays, rectifiers and transformers. Dual-component thermal conductive silica gel has good high and low temperature resistance and excellent air resistance. Weather and radiation resistance; superior dielectric properties, chemical properties and mechanical stability; more effective protection of electrical components.
One-component thermal conductive adhesive has strong adhesion to metal surface and is not easy to peel off. It is widely used for bonding and sealing of PTC sheet and aluminium radiator, as well as coating and fixing of plug-in wires or sheets on sensor surface. It is mainly used in CPU radiator, heat dissipation between crystal sniffer, wafer and radiator, heat conductive glue for the base plate of electric iron, heat conduction of transformer and fixing of electronic components, and then filling.
