    Characteristics

     

    The shelf of styrene butadiene rubber is longer because of its good stability.The property of styrene butadiene rubber is similar to that of natural rubber. It will appear physical and chemical change,whlie its oxidization is slow under the effect of light,heat,oxygen and ozone. More filling agents can be added in styrene butadiene rubber and hardly affact the physicaland mechanical properties of styrene butadiene rubber,therfore, styrene butadiene rubber is fit for the production of rubber products with lower content of rubber. The low temperature resistance and resilience of styrene butadiene rubber is not as good as natural rubber,but styrene butadiene rubber is better than natural rubber as for antifriction ,heat-proof,oil proof and resistance to aging.

     

    Usage

     

    1500 type styrene butadiene rubber is use for tyre,sidewall rubber,general back rubber,line belt,sebific duct sole and other black rubber products with excellent physical properties,and without limit to pollution and color.1502 type styrene butadiene rubber is used for white sidewall rubber,hosepipe,galoshes,sole,rubber fabric and clothes,toys and black and colorful products with excellent physical properties and no pollution.1712 type styrene butadiene rubber is use for tread of tyre,line belt,back rubber,rubber coated wire,cable and general black nidustrial products. 1778 type styrene butadiene rubber is used for light-colored and transparent products such as light-colored sidewall rubber,sebific duct,line belt,fabirc and clothes,galoshes,sole,medicinal product and sports goods,toys and others.

     

    Package

     

    Styrene butadiene rubber is packed in 0.04-0.06mm PE film with paper&PE or PP knitted

    Bag outside. The net weight is35±0.5kg/bag.

     

    Storage&Transport

     

    Styrene butadiene rubber should be trimly piled up with certain space in stack..The hight of stack is not higher than the thickness of 10 pieces of rubbers.It should be stored in a well-ventilated,clean and dry storehouse at ambient temperature,to avoid drench, pollution and direct radiation of sunlight and soak of rainwater while transportion.
