Liquid silicone is a material with good thermal conductivity. It has a high thermal conductivity coefficient and can effectively conduct heat. Liquid silicone is often used in radiators, thermal pastes and other applications that require good heat dissipation performance. TPU is a thermoplastic polyurethane material with elasticity and toughness. TPU itself does not have good heat dissipation performance.
There are many silicone products on the market, such as silicone grease, thermal conductive silicone, silicone heat sink, and our liquid silicone. Does liquid silicone affect heat dissipation? Then we need to understand the concept of "heat dissipation" first. Because air is a poor conductor of heat, a medium is needed between the heat source and the radiator to squeeze the air out of the contact surface.
Liquid silicone is a fluid silicone material, which is mainly synthesized by silicone oil, accelerators and some reinforcing agents. Liquid silicone has the characteristics of rapid vulcanization, excellent tear resistance, resilience, anti-yellowing, thermal stability, heat resistance and anti-aging. Liquid silicone is also non-toxic, heat-resistant and highly resilient. It is suitable for injection molding process and can be used to produce various infant products, medical supplies and electronic products.
Many electronic products use liquid silicone for heat dissipation because the performance of liquid silicone is more suitable than other materials. Conventional liquid silicone heat dissipation can achieve a thermal conductivity of about 0.8, and if it is professionally used for heat dissipation performance, it can be higher. So is liquid silicone good at heat dissipation?
Liquid silicone is a new material mixed with multiple materials. It is a high-tech material. With the continuous improvement of performance, the types of liquid silicone have been popularized to as many as thousands, and the application fields are becoming more and more extensive; it has been popularized in many areas of our daily life.
Electronic liquid silicone is just one of the uses of liquid silicone. In addition to the heat dissipation performance of liquid silicone itself, other properties of liquid silicone are also very demanding. Liquid silicone is an environmentally friendly material. It will not release materials that pollute the environment during use. Liquid silicone is also not corrosive and will not emit acidic and alkaline components, so it will not damage electronic products. For example, the epoxy resin we used to commonly use to pot loose materials is a dangerous chemical that is flammable and explosive. There are great safety hazards in transportation and storage. Secondly, epoxy resin will generate high temperature during operation, about 80 degrees. Under high temperature, it is easier to damage some components with poor temperature resistance. Secondly, the body of liquid silicone is soft after curing, and it will not be dislocated and damaged when encountering collisions during transportation, including the later disassembly will be more convenient, which can play a good role in protecting components from earthquakes.
