If polymer materials have shortcomings, the biggest disadvantage is that they are not fireproof and easy to burn. However, in the flame-retardant elastomer industry, the current technology mainly adopts halogen-free flame-retardant elastomer, mainly including silicone rubber, ethylene propylene rubber, etc. These rubbers are flame-retardant and self extinguishing in the fire, and play a certain role in the fire. However, after continuous high-temperature combustion, there is no machinery left after burning The strength, which turns to ashes, can not keep the integrity of the products, and will cause more dangerous secondary disasters, such as short circuit after the cable sheath and insulation are burned. So, is there an elastomer that can withstand the fire and maintain a certain strength and complete fire resistance?

Technology creates infinite possibilities! There is a wonderful high temperature resistant elastomer - Ceramic silicone rubber, which has very good high temperature resistance. You may not believe it. Its high temperature resistance can reach 1200-1500 ℃!

All the properties of ceramic silicone rubber are inseparable from its special formula structure and combustion performance. Most of ordinary polymer materials become carbon dioxide and water after flame ablation, so it certainly can not play a role in fire protection. However, ceramic silicone rubber can be sintered into hard ceramic objects under high temperature and flame ablation above 500 ℃, and the longer the ablation time and temperature are, the more obvious the ceramic effect is. Some types of ceramic fire-resistant silicone rubber The ablation temperature of the adhesive can reach 1200-1500 ℃.

Ceramic fire-resistant silicone rubber can be processed by conventional rubber processing equipment, and the products produced have various properties of silicone rubber.

If you don't understand, I can say more simply that 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 element. When silicone rubber is burned at high temperature, it breaks down and generates silicon dioxide (one of the main components of stone). Because silicon dioxide has no bonding ability Therefore, it is in the form of powder. When appropriate additives such as silicate fire-resistant filler are added to the formula, the silicon dioxide produced by the decomposition of silicone rubber reacts with the fire-resistant filler, and thus becomes a kind of ceramic product through bonding and agglomeration. The biggest difference between silicone rubber and ordinary silicone rubber is that it is not burned to ashes after encountering fire, but transformed into ceramic body material in a very short time (Note: One of the main components of ceramics is silicon element). Do you think that the temperature resistance of ceramics, stones and other things can reach more than 1000 ℃?

When using ceramic silicone rubber, it can be applied to the sheath or fireproof layer of wires and cables and other products. When encountering the flame, it will form a hard protective layer to prevent the continuous combustion of the flame, play the role of isolating the external flame, so that wires and cables will not form a short circuit, play a good role of line protection, and avoid many fire accidents. In addition, it is a kind of halogen-free environmental protection product, so it can be used as an excellent new type of fireproof material, and can be made into some high temperature resistant super cables. These products are said to have some commercialized products, which can be predicted. It's really a good thing。
