    Comparison of the quality of China dissolved polystyrene-


    butadiene rubber(SSBR FOOD CH) with USA and


    MEXICO Emulsion polystyrene-butadiene rubber


    ( ESBR FOOD)





    The United States, Mexico produced emulsion polystyrene-butadiene rubber English name ESBR,


    ESBR is representative of the use of rosin saponification liquid for polymerization reaction


    production of styrene-butadiene rubber products, and monomer in the reaction process


    (butadiene, styrene) polymerization reaction rate is only about 60%-70%, after the end


    of the reaction and then through the recovery device, the remaining 35% of the styrene


    monomer that has not been completely reacted is recovered, and the polymerized glue


    is separated from the emulsion polystyrene-butadiene rubber product after steam





    Part of the rosin acid is converted into organic acids and saponifieds, so the finished


    emulsion polystyrene-butadiene rubber contains 5%-6% organic acids and a small amount


    of saponification and other residues, so the purity of emulsion polystyrene-butadiene


    rubber is only about 95%, while Mexico's emulsion polystyrene-butadiene rubber


    purity is only about 92%.





    There are a number of enterprises specializing in the production of emulsion polystyrene-


    butadiene rubber, the production of styrene-butadiene rubber products and imported food


    -grade emulsion polystyrene-butadiene rubber products performance is basically the


    same, the domestic factory production of emulsion polystyrene-butadiene rubber


    name specification model ESBR a 1502 type, but is no enterprise to consider the


    use as a food additive, even if you want to use it in the food additive industry,


    the national regulatory authorities clearly stated that according to the national


    standard inspection of food-grade styrene-butadiene rubber, it is impossible to


    pass the audit, Therefore, although the indicators of domestic production of dairy


    polystyrene-butadiene rubber are exactly the same as imported dairy polystyrene-


    butadiene rubber, but that is, domestic dairy polystyrene-butadiene rubber can not


    be used as a food additive product, domestic production enterprises are clear, dairy


    polystyrene-butadiene rubber process production products can not meet the food


    additive styrene-butadiene rubber national standard indicators!




    Now the domestic Ningbo Bowhong high-tech enterprises introduced advanced dissolved


    polystyrene-butadiene rubber projects, after process adjustment, successfully produced


    food-grade dissolved styrene-butadiene rubber products SSBR, tested by national


    authorities according to international and domestic food-grade styrene-butadiene


    rubber standards, the product indicators fully comply with the national standards


    for food additives butadiene butadiene rubber, the English name of dissolved polystyrene-


    butadiene rubber products SSBR, where $ indicates the use of solvent oil (hexane)


    polymerization reaction of styrene-butadiene rubber products, its process requirements


    are high, product purity is high, Its process requires that the butadiene raw material


    is first purified and refined to 99.99% purity of butadiene, styrene is dried to achieve


    99.9% purity, solvent oil water quality must be below 10ppm, the use of butyl lithium


    catalyst, rapid reaction, monomer reaction rate of 99.99%, and then through the


    agglomeration process, post-processing process, molding packaging, finished


    products out of the warehouse!





    It can be seen that emulsion polystyrene-butadiene gum and dissolved polystyrene-


    butadiene gum are three completely different processes, and the quality, quality and


    physical and chemical indicators of the products are completely different.


    According to the domestic food rubber national standard and the international food


    rubber standard comparison "American FCC8, Spanish Royal Decree, French Glue


    Base Order Standard"), and the residue of emulsion polyrubber is completely inconsistent.


    So the national standard of food-grade styrene-butadiene rubber is obviously not applicable


    to the standard range of emulsion polystyrene-butadiene rubber products, the domestic


    also is the emulsion poly process production of styrene-butadiene rubber can not be


    used in the food-grade additive rubber-based industry, and imported emulsion polystyrene-


    butadiene rubber products are widely used in the food processing industry, The reason is


    because in the past because there were no domestic enterprises to produce food-grade


    styrene-butadiene rubber products, the product is still blank in the country, so domestic


    rubber-based users can only rely on foreign imports for a long time, and now there are


    domestic enterprises specializing in the production of food rubber, and domestic production


    of food rubber enterprises participate in the formulation of food rubber national standards,


    but from the current point of view, the relevant departments have not paid attention to


    supervision, although imported emulsion polyrubber can also produce rubber-based products,


    but the rubber product and the national standard indicators requirements are seriously







    But because the China enterprise units using rubber for the production process and processing


    technology of food rubber are not clear, They are partial to think that imported products are better


    than domestic products just by the hibitual from previously manufacture record and have been used


    for decades, so although domestic rubber in the production process and product quality is better than


    imported rubber, but some users are still half-believed, not a large number of use, always think that


    the United States products are good, after several years by the rubber base company professional


    and technical personnel and authoritative departments on the domestic food rubber test evaluation,


    Most rubber-based companies have confirmed the fact that domestic rubber is superior to imported


    rubber products inclduing world famous food grade rubber (SBR FOOD CH) users.





    China food-grade styrene-butadiene rubber (SBR FOOD CH) have obvious advantages, good


    product quality, white color, rubber purity up to 99.89%, no peculiar smell, enterprise procurement


    volume can be ordered with the production plan, large price advantage, reduce inventory,


    involving rubber inventory capital pressure is small, delivery pole service and other advantages!


    Welcome all rubber-based users to purchase food-grade styrene-butadiene rubber products produced


    by Changhong Hi-Tech!
