Flame retardant liquid silicone rubber is a two-component additive liquid silicone rubber with a solid content of 100%, which belongs to non hazardous chemicals. Its typical products include liquid flame-retardant coated silicone rubber, high rebound flame-retardant liquid silicone rubber, etc. The main components are polydimethylsiloxane, silicate and other substrates, supplemented by various flame retardants such as aluminum hydroxide, magnesium hydroxide, platinum compounds, titanium dioxide, phosphorus/bromine flame retardants, etc.

This material has a wide working temperature range, can adapt to environments ranging from -100 ℃ to+200 ℃, and has excellent characteristics such as heat resistance, flame retardancy, UV aging resistance, water and moisture resistance, breathability, and resilience.

From the perspective of flame retardant mechanism, it achieves multidimensional flame retardant effect by adding flame retardants: aluminum hydroxide and magnesium hydroxide decompose and absorb heat, which can reduce material temperature; The decomposition products form an isolation layer that can isolate oxygen and heat sources; Capturing free radicals (such as HO ·) can interrupt the combustion chain reaction; Releasing non combustible gases such as carbon dioxide and water vapor can dilute the concentration of combustible gases.

In terms of physical properties, the material has low viscosity and good fluidity, and can be formed through various processes such as scraping, roller coating, injection molding, and compression molding; The hardness after vulcanization is usually between 35-45 Shore A, with a tensile strength of 3.0-4.0 MPa, elongation of 200%, and tear strength of 3.0-5.0 MPa. In terms of environmental protection and safety, it complies with the EU ROHS standard, is non-toxic, harmless, and has excellent biocompatibility. The extract of medical grade products can be less than 1ppm, and the antibacterial rate exceeds 99%.

It has a wide range of applications. In the electronic and electrical field, it is commonly used for moisture-proof, insulation coating and potting of electronic components. For example, transparent gel potting can achieve shockproof and waterproof and support fault detection. It is also used in power battery package sealing, photovoltaic junction box potting, cable joint protection and other scenarios; In the medical field, medical grade products are suitable for pacemaker leads, artificial joints, minimally invasive surgical instruments, etc., with strict requirements for high biocompatibility and low extraction; In the automotive industry, it can be used for lightweight components of new energy vehicles (such as seals, insulation pads) and high-temperature resistant components (long-term use at 200 ℃); In terms of consumer electronics, wearable devices (such as smart watch straps), 5G communication device seals, TWS headphone seals, and other scenarios require high transparency (transparency>90%) and low hardness (Shore A20-30); The fields of architecture and industry involve fiberglass cloth coating, high-frequency embossing molds, ceramic/toy molding, furniture sealing, etc.
