Properties

Slightly foul odor and bitter taste, nonpoisonous. Specific gravity: 1.46-1.52.Soluble in ethyl acetone, acetone, dilute solution of sodium hydroxide and sodium carbonate, ethyl alcohol. Not easily soluble in benzene. Insoluble in water and gasoline.
Application

Used for NR, IR, SBR, NBR, HR and EPDM. One of the mainly used acidic accelerators currently and a medium fast primary accelerator. Imparts excellent aging properties, when used both alone and in combination with DM, TT and many others, mainly basic accelerators for higher activity. But care should be taken because it has a slight tendency to scorch. Unsuitable for use in the manufacture of food contact materials. Mainly used in the manufacture of tires, tubes, footwear, rubber belts and hoses etc.

MC NYLON is recognized as the most widely used and known engineering plastic in the current market. PA6 has the best performance, very tough, even at low temperatures, and high surface hardness, mechanical lower shock, and abrasion resistance. Combined with these characteristics and good insulation, and chemical properties, it has become common-level materials. It`s widely used in a variety of mechanical structures and spare parts. Compared to PA6, PA66 own the higher hardness, rigidity, better resistance to wear and heat deflection temperature. Temperature resistance from -40℃ to 110 ℃.

  • Advantages:
    ♦ High strength and stiffness 
    ♦ High impact and notch impact strength 
    ♦ High heat deflection temperature
    ♦ Good at dampening 
    ♦ Good abrasion resistance
    ♦ Low coefficient of friction
    ♦ Good chemical stability against organic solvents and fuels
    ♦ Excellent electrical properties, ease of printing and dyeing
    ♦ Food safe, noise reduction

    Disadvantages:
    ♦ Poor dimension stability, electrical and mechanical properties may become affected by absorbing moisture or water
    ♦ Poor acidproof ability, can`t dye with acid or touch overmuch acid
