Nitrile rubber (NBR): this material is the highest temperature up to 130 degrees, hardness of 50-90 degrees are available, complete specifications, it has good mechanical properties, resistance to mineral-based lubricants and grease. Fluoroelastomer (FPM): the temperature of this material can reach 240 degrees of high temperature, complete specifications, it is known for high temperature resistance and chemical resistance and other good performance. In addition, it also has good resistance to aging and oxidation, very low gas permeability (especially for really high altitude devices).
Ethylene Propylene Diene Rubber (EPDM): The temperature range is from -50 degrees to 150 degrees Celsius, and the wide has the characteristics of resistance to hot water, steam, aging and chemicals. It is suitable for hot water, steam, detergents, potassium hydroxide solution, silicone oil and grease, a variety of dilute acids and chemical (pharmaceutical) products. It is particularly recommended for its resistance to glycol brake fluids, but it is not suitable for all mineral oil products (lubricants, fuels).
Silicone rubber (SI): silicone rubber has the widest working temperature range (-60-180 ° C), harmless, non-toxic and tasteless, excellent resistance to ozone aging, oxygen aging, light aging and weather aging performance, excellent electrical insulation properties, special surface properties and physiological inertia, high permeability.
There are also many kinds of materials such as: polyurethane rubber (PU) natural rubber (NR) butyl rubber (BU) sulfur vulcanised polyethylene (CSM) polytetrafluoroethylene (PTFE) chloroprene rubber (CR) acrylate rubber (ACM) and many other materials.
