There are various type of rubber o ring materials, here introduce some common used. Each material have more or less subcategory which has different performance. If you need more information, contact us.

Besides, there are many that do not be listed below, such as IIR, CSM, etc. In addition, there are other materials can be made as o ring, such as PTFE, graphite, etc.

Natural rubber (NR)

It has excellent resilience, tensile strength, elongation, wear resistance, tear and compression set properties superior to most synthetic rubbers. It is not resistant to oil, weather, ozone and oxygen. The operating temperature range is - 60~90 ℃.

Styrene butadiene rubber (SBR)

Styrene butadiene rubber (SBR) is a copolymer of butadiene and styrene. Styrene butadiene with 10% styrene has good cold resistance, and styrene butadiene with 30% styrene has excellent wear resistance. The product has poor oil resistance and aging resistance. The operating temperature range is - 40~110 ℃.

Neoprene (CR)

Neoprene rubber (CR) is a chloroprene polymer, weather resistant, ozone aging resistant, self extinguishing, oil resistant, second only to nitrile rubber, with excellent tensile strength, elongation, resilience, and good adhesion with metals and fabrics. The products are not resistant to synthetic diester lubricating oil and phosphate hydraulic oil. The operating temperature range is - 40~120 ℃.

Nitrile butadiene rubber (NBR)

Butadiene acrylonitrile is a copolymer that is used to make nitrile butadiene rubber (NBR). Typically, acrylonitrile concentration ranges from 18% to 26% to 40%. The oil resistance, heat resistance, and wear resistance all improve with increasing content, but the cold resistance is the contrary. Better than NBR in terms of wear resistance, high temperature resistance, and oil resistance is NBR that contains a carboxyl group. The items are not resistant to phosphate hydraulic oil, ozone aging, or the elements. The temperature range for operation is - 40 to 120 °C.

Ethylene propylene rubber (EPDM, EPDM)

Ethylene propylene rubber is a binary copolymer (EPDM) of ethylene and propylene or a ternary copolymer (EPDM) of ethylene, propylene and diene olefins. It is weather resistant, ozone resistant, resistant to steam, phosphate hydraulic oil, acid, alkali, rocket fuel and oxidant, and has excellent electrical insulation performance. The products are not resistant to petroleum based oils. The operating temperature range is - 50~150 ℃.

Polyurethane rubber

Rubber made of polyurethane is polyurethane. Typically, polyester (AU) and polyether come in two different forms (EU). It offers exceptional tensile strength, rip strength, and wear resistance, as well as exceptional resistance to ozone, oil, and radiation from the sun. The temperature range for operation is - 40 to 80 °C. Ester, ketone, phosphate hydraulic oil, concentrated acid, alkali, steam, etc. are all inappropriate substances to come into contact with.

Acrylate rubber (ACM)

Acrylate rubber (ACM) has excellent heat resistance, oil resistance, cold resistance, ozone resistance and other properties.

Silicone rubber

Silicone rubber has excellent heat resistance, cold resistance, aging resistance, excellent insulation resistance and dielectric properties, and good heat conductivity, but it has poor strength and tear resistance, is not oil resistant, and is expensive. The operating temperature range is - 70~220 ℃.

Fluoroelastomer (FKM)

Fluoroelastomer (FKM) commonly used are fluororubber - 26 and fluororubber - 246. Fluorine rubber has outstanding heat resistance, oil resistance, acid resistance, alkali resistance, excellent aging performance and electrical insulation performance, flame retardant, and low permeability. But the low-temperature performance is poor. Generally, the temperature range is - 20~200 ℃, and can reach 250 ℃ in a short time.

Fluorosilicone rubber (FMVQ)

Fluorosilicone rubber (FMVQ) has low strength and tear resistance but great oil resistance, chemical resistance, heat resistance, cold resistance, and aging resistance. The temperature range for operation is - 60 to 175 °C.
