Sealant for automotive airbags

Provides excellent adhesive performance, such as peel strength and cohesive failure, when sealing joints or seams between two pieces of fabric. The first and second pieces are bonded together and then sewn with one or more stitches to provide sufficient mechanical strength. Seams are bonded using a silicone adhesive to ensure sufficient airtightness or pressure retention when the airbag deploys. Thermal conductive gel inherits the advantages of silicone materials, such as good compatibility, weather resistance, resistance to high and low temperatures, and excellent insulation properties. At the same time, it is highly malleable, capable of filling uneven interfaces and meeting heat transfer requirements across a wide range of applications. Compared to thermal pads, thermal conductive gel is softer and has better surface affinity; it can be compressed to a very low thickness, significantly improving heat transfer efficiency, and can be compressed to as little as 0.1 mm, at which point the thermal resistance ranges from 0.08 °C·in²/W to 0.3 °C·in²/W, matching the performance of some silicone greases. Furthermore, thermal conductive gel has virtually no hardness and does not induce internal stress in equipment after application. Compared to thermal pads, it adheres more easily to joint surfaces; compared to thermal grease, it offers better sealing properties and is less prone to powdering.

Heat-conducting gel for thermal modules

Two-component addition-curing, high-thermal-conductivity potting compound for chargers and high-power on-board modules

Thermal potting for automotive chargers; may also be used for thermal potting protection of high-power on-board modules and electronic components All electronic components within an on-board charger (OBC) must be encapsulated within a sealed housing to prevent environmental contamination. These high-heat-generating electronic components—such as chips and MOSFETs—must be in direct contact with the inner surface of the die-cast metal housing to ensure effective heat transfer (heat dissipation). The high thermal conductivity of the potting compound improves heat transfer by filling air gaps caused by surface irregularities on the components and heat sinks. This ensures that the heat generated by the components comes into full contact with the inner walls of the die-cast metal housing, facilitating efficient heat transfer. At the same time, the low-stress silicone elastomer effectively protects the electronic components whilst providing waterproofing and electrical insulation.

Low-stress encapsulation silicone gel

For low-stress potting of control modules such as IGBTs, ECUs and BSGs in electric vehicles. Features: 1. Once cured, the gel exhibits good adhesion and sealing performance on many substrates, and offers excellent resistance to thermal cycling, heat and mechanical shock; 2. The gel retains most of the stress-relief and self-healing properties of the liquid phase whilst maintaining the dimensional stability of an elastomer, thereby achieving ideal impact resistance and vibration damping effects; 3, The raw materials are purified using proprietary technology, resulting in characteristics such as non-corrosiveness and low molecular content; 4. The two-component mixture does not gel rapidly upon mixing, providing a suitable working time; however, it cures rapidly once heated. The curing time can be freely controlled, and no by-products are generated during curing, nor does any shrinkage occur; 5. It possesses excellent electrical insulation properties, such as high dielectric strength and volume resistivity, and is resistant to salt spray corrosion and damp heat.
