| There are many kinds of rubber, natural rubber (NR, styrene-butadiene rubber (SBR), butadiene rubber (BR), isoprene rubber (IR), nitrile butadiene rubber (NBR), butyl rubber (IIR) chloroprene rubber (CR), ethylene propylene rubber (EPM, EPDM), silicone rubber (Q), fluorine rubber (FPM), etc.
Paraffin oil is suitable for saturated rubber, with some professional knowledge.
Difference between unsaturated and saturated rubber rubber, such as its chemical structure to distinguish, is to see all kinds of rubber of rubber on the main chain molecules have double bond = exists, namely = on structured exist for unsaturated rubber, namely no saturated rubber. = there is no double bond, unsaturated rubber in the molecular chain high chemical activity, easy crosslinking reactions and the vulcanizing agent. Fast curing rate, due to the double bond isolation effect, high molecular activity, good flexibility, low brittle temperature, cold resistant, but easy to react with oxygen and ozone, ageing resistance, and the main chain of the saturated rubber with carbon carbon bond, chemistry stability is good, not easy to react with oxygen and ozone, has good heat resistance to medium ageing resistance, generally cannot use sulfur curing system, but the calculation peroxide, resin or quinones vulcanization
Paraffin oil is suitable for epdm rubber and can be selected according to the vulcanization temperature of rubber.
For example, the vulcanization temperature of the rubber mat of a manufacturer is 150 degrees Celsius.
