Characteristics and applications of liquid silicone foam in new energy vehicles Liquid silicone foam is used as a sealing gasket for the battery box, reducing the bumps and vibrations of the battery box during the operation of the electric vehicle, while also realizing the lightweight, automation and low-cost requirements. It has good sealing, low specific gravity, high flame retardant, wrapped around the bottom of the power battery, as a buffer, anti-slip and anti-vibration effect. It can adapt to various harsh internal environments, and is suitable for sealing parts of new energy vehicles, component protection, and various cushioning applications; it also provides excellent flame retardancy, heat insulation and shock absorption performance in various transportation equipment. Liat Silicone is available in rolls of different thicknesses and can be easily processed to the required size. Properties of liquid silicone foam: 1. excellent flame retardancy 2. high and low temperature resistance 3. low specific gravity, fine and uniform pore size 4. waterproof, shock absorption, sealing, heat insulation 5. UV and ozone resistance 6. very adaptable to mechanical fatigue 7. good resistance to compression deformation and creep resistance Liquid adhesive foam applications are becoming increasingly widespread, because of its excellent performance of both silicone rubber and foam materials, not only has the rubber's high rebound, aging resistance, and sound absorption Because it has the excellent performance of both silicone rubber and foam material, not only has the high resilience of rubber, aging resistance, but also has acoustic, shock absorption and other properties of foam, mostly used for waterproofing, vibration damping, gaskets, sound insulation, insulation, aviation insulation and other performance requirements of the situation is relatively high. Many of today's automobile interior materials, such as flooring, roof, steering wheel, car seats, etc. are polyurethane foam materials, on the one hand, because the polyurethane foam material technology is relatively mature, performance in line with the use of standards; on the other hand, because of the lower price of polyurethane foam materials. However, polyurethane foam material weathering performance is poor, flammable and combustion process releases a large number of toxic gases harmful to humans. Therefore, with the promotion of organic silicone foam material and people's awareness of its enhancement, the future of liquid silicone foam material is expected to replace the traditional polyurethane foam foam material. New energy vehicles in the application of liquid silicone foam materials New energy electric vehicles, the key to the technology of electric vehicles in the high energy density lithium battery full electric technology and performance. Lithium batteries in the use of the process must maintain strict waterproof and dustproof requirements, and easy to heat spontaneous combustion is the number one problem affecting the use of electric vehicles. In heavy rain, shallow, haze and other conditions, in order to meet the requirements of the car driving process of power battery sealing and buffer protection, liquid silicone foam material can be applied to the power battery. Silicone foam potting material is used to protect individual battery cells. Liquid silicone foam is also widely used in the treatment of anti-light leakage, dustproof, shock absorption, and increased airtightness around the car lights; and the treatment of anti-noise and gap filling around the speakers and stereos of electric cars.
