Molecular formula : MW : CAS :
nature : it refers to the low-temperature (-20 to -80 ° C) under the conditions still maintains its original flexible rubber products and its tributaries. Hardy mainly under its glass transition temperature. For example, natural rubber is -73 ° C, butyl rubber is -67 to -69 ° C, silicone rubber is -65 ° C ~ 74. Cold-resistant rubber raising methods often add hypothermia plasticizers, plasticizers such as DOS, DOA, or used in other cold tolerance and with good rubber. General hardy rubber products used and use of natural rubber. General common cold rubber products used natural rubber. Most of the aviation industry products using silicone rubber or fluoro rubber. Hardy to require a higher degree of products can be used butadiene rubber (glass transition temperature of -100 ° C).
