NR/SBR/BR/NBR/HNBR/EPDM/CR/IIR/ECO/FKM/FPM/FVMQ/VMQ/FEPM O ring

Shengda rubber has many years production experience and industry field application experience, we aimed at the different harsh sealing environments and developed various of materials suitable for applications. Improving all customers' profit and saving all customers' cost. Shengda automatic production equipments and advanced testing equipments provide a strong guarantee for the manufacture of high quality all kinds of o ring products.

EPDM
Good resistance to hot water and steam, detergents, caustic potash solutions, silicone oil and greases, many polar solvents, and many diluted acids and chemicals, along with a high level of ozone resistance. EPDM materials are totally unsuitable for use with all mineral oil products (lubricants, fuels).

FKM
Good chemical resistance to mineral oils and greases, synthetic oils and greases, engine, transmission and ATF oils to approx. +150°C, fuels, non-flammable hydraulic pressure fluids HFD, aliphatic, aromatic and chlorinated hydrocarbons, water to max. +80°C, excellent resistance to weathering, ozone and ageing, very low gas permeability (and therefore excellent for vacuum application) and resistance to a wide range of chemicals.

HNBR
HNBR is obtained by fully or partially hydrogenating NBR. It leads to considerable improvement in resistance to heat, ozone and ageing, and gives it very good mechanical properties, e.g. good resistance to wear. The media resistance compares to that of NBR. HNBR has a good resistance to some refrigerants. The temperature application range is from -30°C to +150°C.

NBR
Good chemical resistance to mineral oils and greases, hydraulic oils H, HL, HLP, non-inflammable hydraulic pressure fluids HFA, HFB, HFC to approx. +50°C and water to max. +80°C

VMQ
Good resistance to water (up to 100 °C), aliphatic engine and transmission oils, animal and plant oils and fats. VMQ is generally not resistant to fuels, aromatic mineral oils, steam (short term up to 120 °C possible), silicone oils and greases, acids and alkaline compounds.
