    Interpretation of FESTO solenoid valve three kinds of sealin

     Understanding of several different FESTO solenoid valve sealing material, only users understand the nature of electromagnetic valve manufacturing;
    Of course, good solenoid valve manufacturing material is the important details to determine the quality of solenoid valve;
    FESTO solenoid valve is often used in several parts of the seal material:
    (1) NBR rubber (butadiene rubber nitrile)
    A method for the polymerization of butadiene and acrylonitrile by emulsion polymerization. Selection of the benefits of this model is that: the main use of low temperature emulsion polymerization process, oil resistance, high wear resistance, good heat resistance, strong adhesion.
    Despite the good product, but also has shortcomings. Its disadvantages are low temperature resistance, ozone resistance, poor electrical performance, low elasticity. In addition, it has good water resistance, air tightness and excellent bonding properties.
    Are widely used in: all kinds of oil resistant rubber, oil resistant gasket, gaskets, casing, flexible packaging, flexible hose, dyeing roller, plastic cable materials, in the automobile, petroleum, copying and other industry become essential for elastic materials.
    (2) EPDM three EPDM (Ethylene-Propylene-Diene Monomer)
    Three EPDM is ethylene, propylene and non conjugated diene copolymer three.
    The main characteristic of EPDM is its ability to resist oxidation, ozone and corrosion resistance.
    Because of the three yuan ethylene propylene rubber is a polyolefin family, it has an excellent curing properties.
    Among all rubber, EPDM has the lowest proportion. It can absorb a large amount of filler and oil and the characteristics of the impact is not big. So it can be made of low cost of rubber compound.
    (3) VITON fluorine rubber (FKM)
    The rubber containing fluorine, the content of fluorine in the form of a single body and a variety of types;
    At present, it is the first time that the fluorine element in the six fluorinated fluoride system is listed in the name of "VITON",
    Chemical resistance, resistance to most of the oil and solvents (except ketones, esters), weather resistance, ozone resistance are good, but the cold resistance is bad;
    The general is widely used in car, B products, chemical factory of seals,
    The use of the temperature range of -20 - 260, the use of low temperature resistance type can be used to apply to -40, for the higher price.
