    What's Each Rubber's Typical Features ?

     

    NBR Rubber Features:

    Nitrile rubber (NBR, Buna-N) provides excellent resistance to petroleum oils as well as mineral and vegetable oil. Nitrile rubber also offers strong resistance to heat aging - often a key advantage over natural rubber.

    Nitrile rubber performs well in carburetor and fuel pump diaphragms, aircraft hoses, seals and gaskets as well as oil-lined tubing. Due to its versatility, nitrile is used in applications involving not only oil and fuel resistance, but those applications requiring resistance to heat, abrasion, water, and gas permeability.

    FKM Rubber Features:

    Vi-ton belongs to the Fluoroelastomers (FKM/FPM) group of rubber compounds. There are many grades and hardness variations to solve most applications with various formulations to meet specific requirements of temperature and chemical resistance. Typical uses include:excellent heat resistance,good mechanical properties,good compression set resistance,resistance to wide range of oils and fuels,resistance to solvents; especially all aliphatic, aromatic and halogenated hydrocarbons and acids.

    EPDM Rubber Features:

    EPDM rubber is a high density rubber primarily used for outdoor applications. It has dynamic and mechanical properties between natural rubber and synthetic rubber.

    Do not use EPDM if continual contact with petroleum based products is required.

    Not recommended for usage in food applications or those that are exposed to aromatic hydrocarbons.

    HNBR Rubber Features:

    Hydrogenated Nitrile Butadiene Rubber (HNBR), also known as Highly SaturatedNitrile (HSN), is special class of nitrile rubber (NBR) that has been hydrogenated to increase saturation of the butadiene segment of the carbon polymer backbone. Subsequent improvements to the material properties, over that of a nitrile rubber (NBR), include greater thermal stability, broader chemical resistance, and greater tensile strength.

    HNBR is classified by ASTM as a DH-type polymer. This classification indicates 150ºC service temperature as well as less than 30% swell in IRM 903 oil. HNBR can be formulated to meet application temperatures ranging between -50°C and 165ºC.

    SBR Rubber Features:

    1.Main materials: Styrene-butadiene rubber (SBR), a general-purpose synthetic rubber,produced from a copolymer of styrene and butadiene. Exceeding all other synthetic rubbers in consumption, SBR is used in great quantities in automobile and truck tires, generally as an abrasion-resistant replacement for natural rubber (produced from polyisoprene).

    2.Available place: They are widely used in automobile, electrical appliances, building vibration isolation and other industry. For example, air blower, water pump, instrument, measuring of ships and so on.

    3.Main performance: SBR has similar chemical and physical properties to natural rubber, with generally better abrasion resistance,outstanding strength,good creep and stress relaxation resistance and low cost,etc. It is not recommended to use SBR in applications that involve ozone, strong acids, oils, greases, fats and most hydrocarbons.

    Neoprene Rubber Features:

    Neoprene Rubber, also known as neoprene polychloroprene, is an extremely versatile synthetic rubber with more than 75 years of proven performance.

    In the automotive world, neoprene is used for many under-the-hood and underbody parts that require a reasonably priced, mid-performance polymer with a good all-around balance of performance properties.

    Natural Rubber Features:

    Natural rubber was originally derived from latex found in the sap of rubber trees. The purified form of natural rubber can also be produced synthetically. Natural rubber is an ideal polymer for dynamic or static engineering applications.

    Caution: Natural rubber is not recommended for applications where the rubber part will be exposed to ozone, oils, or solvents.

    PU/Polyurethane Rubber Features:

    Polyurethane is an organic polymer. Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Polyurethane is a widely used compound due to its superior strength, tear and abrasion resistance. Polyurethane also provides excellent permeation resistance.

    Features:

    Good hydraulic oil and gas resistance Resistant to pure aliphatic hydrocarbons Resistance to mineral and silicone oils and greases Resistant to water, oxygen, ozone and aging Excellent tear and abrasion resistance Available in multiple types and compounds to meet performance and cost requirements
