Silicone rubber thermal aging hi a bul berah chuan side chain oxidation leh main chain-a siloxane bonds breaking hmanga lo awm a ni. Chuvangin, a kawng khatah chuan silicone rubber-a heat resistance chu a side chain-ah a innghat a ni.
A lehlamah chuan main chain breakage hi sealing heat resistance an ti thei bawk a, hei hi oxidation aging nen a danglam hle. Main chain-a flexibility leh end group awmna nen a inzawm a ni. Chubakah, tui, acid, bases, etc. awmna hian chain tihchhiatnaah nasa takin hma a sawn a ni.
