What is the difference between asbestos sealing materials and also non-asbestos sealing materials?We might summarize it:
Asbestos sealing materials are more resistant come high temperature than non-asbestos sealing materials. The main components of asbestos sealing products are asbestos, fillers and also rubber. Among them, the temperature resistance that asbestos and fillers is really high. The main components of most non-asbestos sealing products are mineral fibers, organic fibers, fillers and also rubber. Amongst them, the temperature resistance that organic fibers is normally At around 200℃, the highest temperature resistance of asbestos gaskets has actually reached about 1000℃.

2. Asbestos sealing material has greater mechanical toughness than non-asbestos sealing material.
(1) The surface of the asbestos fiber is attached v multivalent metal cations, which easily forms a solid interface v the negatively fee rubber ~ above the surface, which improves the bonding toughness of the rubber fiber, the is, the mechanical strength of the asbestos sealing material. The non-asbestos mineral fibers right now used are not as great as asbestos in straight affinity v the rubber matrix, for this reason the bonding stamin of rubber yarn is no as great as asbestos.
(2) Asbestos fibers deserve to be subdivided practically indefinitely, and the details surface area is larger than the of non-asbestos mineral fibers, therefore the reinforcement impact is obvious.
(3) The tensile stamin of asbestos fiber is greater than that of non-asbestos fiber, for this reason the reinforcing impact of asbestos fiber is obvious.
3. The non-asbestos sealing material is much more compact 보다 the asbestos sealing material. Because the asbestos-free sealing material has actually high filler content and different particle sizes, that can fully fill the micro gaps the the rubber fiber. Because that example, Bode Seal uses a high-precision material choice screen, and the precise screening of multiple raw products is much more uniform. In addition, the non-asbestos fiber go not have actually a tubular structure choose the asbestos fiber, however a heavy structure, therefore the compactness is better.

4. As we every know, the seriousness the asbestos materials on human being health has long been banned indigenous the use of asbestos products in arisen countries such together Europe, America and Japan, and my country will progressively phase the end asbestos sealing materials and also replace them with non-asbestos sealing materials.

5. Asbestos-free sealing products are environmentally friendly, and also asbestos sealing materials are non-environmental friendly. Asbestos fibers consisted of in asbestos sealing products are vulnerable to silicosis in humans, and also asbestos-free sealing materials do no contain asbestos fibers.
