A wonderful high temperature resistance of the elastomer - ceramic silicone rubber

Polymer materials if there are shortcomings, the biggest disadvantage is not fireproof, easy to burn, however, in the flame retardant elastomer industry, the current technology mainly uses halogen-free flame retardant elastomers, mainly silicone rubber, ethylene propylene rubber, etc., these rubber in the fire burning with flame retardant and self-extinguishing, in the fire plays a certain role, but after continuous high temperature combustion, the burnt residue has no mechanical strength, Become ash, can not maintain the integrity of the product, will cause more dangerous secondary disasters, such as the sheath and insulation of the cable burned, resulting in short circuit. So, is there an elastomer that can withstand the burning of a fire and maintain a certain strength?

Technology creates endless possibilities! There is a wonderful high temperature resistance elastomer - ceramic silicone rubber, has very good high temperature resistance, you may not believe it, its high temperature resistance can reach 1200 ~ 1500℃!

All this property of ceramized silicone rubber is inseparable from its special formula structure and combustion performance. Most of the ordinary polymer materials have become carbon dioxide and water after flame ablation, so it certainly cannot play the role of fire prevention, but ceramic silicone rubber can be burned into hard ceramic objects at high temperatures above 500 ° C and under flame ablation, and the longer the ablation time and the higher the temperature, the more obvious the ceramic effect. The ablation temperature of some types of ceramic refractory silicone rubber can reach 1200 ~ 1500℃.

Ceramic refractory silicone rubber can be processed by conventional rubber processing equipment, and the products produced have the properties of silicone rubber.

If you don't understand, I can say it more simply, that is, ceramic silicone rubber is a new type of polymer elastomer designed with a new formula that contains a certain proportion of other inorganic elements in addition to silicon. When silicone rubber is burned at high temperature, it will crack and decompose into silicon dioxide (one of the main components of stone). So it is in powder form, when the appropriate additives such as silicate refractory fillers are added in the formula, the silica generated by the decomposition of silicone rubber reacts with the refractory fillers, thus becoming a ceramic product by bonding, the biggest difference between it and ordinary silicone rubber is that it is not burned into ashes after the fire, but in a very short time into ceramic material (Note: One of the main components of ceramics is silicon), you think, the temperature resistance of ceramics, stones and the like is not capable of more than 1000 ° C?

When the use of ceramic silicone rubber can be applied to the sheath or fire protection layer of wire and cable products, the flame will form a hard protective layer to block the continued burning of the flame, and play the role of insulating the external flame, so that the wire and cable will not form a short circuit, play a good line protection role, to avoid the occurrence of many fire accidents. In addition, it is a halogen-free environmental protection product, so it can be used as an excellent new fireproof material, can be made into some high-temperature super cables, these products are said to have some commercial products, can be predicted, this is really a good thing...
