Ceramicized silicone rubber is an innovative fireproof material, and its unique properties have been widely used in various fields. This material not only has excellent combustion characteristics, which can effectively prevent the spread of flames, but also has excellent thermal shock resistance, which can maintain the stability of its structure and properties in high-temperature environments. In addition, ceramicized silicone rubber has environmentally friendly properties that can reduce the environmental impact during production and use.
Ceramicized silicone rubber has similar properties to ordinary rubber materials at room temperature, but at high temperatures, it can form a dense and hard ceramic body, which effectively prevents the spread of flames. The main components of this material include a silicone rubber matrix, a porcelain filler (stone ceramicized flame retardant), a flux, a reinforcing agent and a vulcanizing agent. Among them, the silicone rubber matrix has good insulation properties, aging resistance and arc resistance. Porcelain fillers are the key to ceramicization, which can react with silicone rubber and fluxes to form ceramic bodies.
Ceramicized silicone rubber has many advantages. It can be sintered into a self-supporting ceramic body in an open flame or at high temperatures, preventing the flame from spreading internally. The ceramicized sintered body has high hardness and has certain flexural strength and press-through strength. Its flexural strength is much greater than that of ordinary silicone rubber, and as the temperature increases, the strength increases. In the simulated firefighting process, the ceramicized silicone rubber sintered body does not explode and shows good thermal shock resistance.
Composite ceramic flame retardant for stone ceramicized silicone rubberBrief introduction.
Stone composite ceramic powder is halogen-free, low smoke, non-toxic, harmless environmentally friendly flame retardant composite material, after adding polymer can form a self-supporting ceramic body in the process of low temperature and short-term combustion, and has good physical strength, playing a role in fire prevention;
Under the condition of high temperature and long-term or under the flame, a ceramic body with higher strength can be formed, so as to better protect the normal operation of internal components, spray, vibration will not fall off, and have better heat insulation ability, such as the normal power supply of wires and cables;
In addition, it can also be used in fire-retardant sealant strips, fire-resistant plastics and rubbers, fire-retardant potting compounds and other products with strict flame retardant and fire protection requirements

In addition, ceramicized silicone rubber has excellent environmental properties. The main residue produced during its combustion is non-toxic silica, which is harmless to humans and the environment. Compared to other materials, ceramicized silicone rubber produces less smoke when burned, which improves the visibility of the fire scene and helps to carry out fire extinguishing work. At the same time, it will not produce toxic exhaust gas or harmful solution, avoiding secondary pollution to the surrounding environment after fire. Ceramicized silicone rubber is also renewable and can be reused, reducing the waste of resources.
Comparison of the performance of ceramicized polyolefins
The material is less dense;
The strength of the porcelain is comparable;
There is still a big gap between the strength of low-temperature porcelain and that of ceramicized silica gel.
Whether in wire and cable, new energy vehicles, construction industry, or aerospace field, ceramic silicone rubber is an innovative material that brings new solutions to the field of fire and flame retardant with its excellent performance characteristics. It is like a solid guardian, improving the fire performance of items, and providing a solid guarantee for people's life safety and environmental protection. Looking to the future, ceramicized polymers are expected to play their unique role in more areas to protect our safety.
