2019/1/14· EPDM beats SBR in tensile strength and resistance to heat aging and weathering. Nitrile butadiene rubber (NBR): Nitrile is king of elastomers when it comes to oil- and fuel-resistance. One attraction to NBR is its stability in low temperatures, with the ability to survive extreme cold of -30˚C/ -22˚F, which EPDM and Silicone can’t match.
THE GENERAL CHARACTERISITCS OF EPDM RUBBER is as follows: 1. EPDM Rubber is having very good Heat, Weather, Ozone resistance. 2. Good resistance to Steam, Polar substances, Ketones, diluted acids and alkalines 3. Excellent insulation
Ethylene-propylene (EPM/EPDM) Working Temperature Range : -45°C to +120°C. EPDM has good resistance to ozone ageing and weathering, water and steam, Dilute acid, alkalies ketones, alcohol, fire retardent hydraulic fluids and hydraulic brakes fluids, this elastomer must not come in contact with mineral oils and greases. Chemical properties.

EPDM in the radiator hose formulation results in enhanced ageing resistance, which is believed to be an indirect consequence of the higher peroxide-curing efficiency of VNB-EPDM. Heißluftalterung von peroxidisch vernetztem EPDM mit 5-Vinyl-2-Norbornen als
If elastomers are pushed beyond their ageing resistance parameters, they will suffer from cracking, splitting and/or hardening. Low temperature flexibility The TR test (low temperature retraction) provides a measure of the rate of recovery of an elastomeric material after it has been subjected to low temperature.
