Propylene Ethylene Diene Monomer is an ethylene-propylene copolymer with a minor amount of a diene monomer that creates chemically unsaturated ethylene groups pendent from the main saturated chain. These aid cross-linking reactions without jeopardizing the polymer backbone's integrity. EPDM has exceptional heat, ozone, and chemical resistance thanks to this property. Physical qualities are excellent, and polar fluid resistance is generally good. EPDM can be compounded to provide great electrical resistance and has excellent low-temperature resistance.
Natural rubber is the only non-synthetic rubber on the market, and it has been in use since the turn of the century. It's made from the sap of the Hevea Brasiliensis tree, which can be found in sustainable plantations. It degrades completely.
One of the first oil-resistant synthetic rubbers was chloroprene rubber (CR), often known as Neoprene®. Its resistance to petroleum-based oils and fuels, on the other hand, is only moderate. It's a terrific all-around rubber with a decent combination of physical and chemical qualities. It outperforms natural rubber in terms of chemical, oil, ozone, and heat resistance, but it has a lower degree of physical qualities. Chloroprene has a weak water absorption rate and poor electrical characteristics. It has a low gas permeability and great flame resistance, as chloroprene is one of the few self-extinguishing rubbers. Neoprene provides excellent rubber-metal bonding as well as a high level of durability.
SBR (Styrene Butadiene Rubber) is a low-cost general-purpose rubber. Physical strength, resilience, and low-temperature qualities are typically lower to Natural Rubber, however heat-aging properties and abrasion resistance are usually superior.
