PVC IMPACT MODIFIER MBS RESINS
I Brief introduction
    MBS resins products are graft copolymers of methyl methacrylate(M),butadiene(B) and styrene. It is used for modified PVC to make it have special performances or improve its comprehensive performances. MBS resins have extensive applications and are almost used for all transparent PVC as impact modifier, such as PVC transparent bottles, transparent sheets and transparent films etc., and can also used for high impact opaque PVC products as tubular products and pipe fittings.
    In 1991, our company successfully developed MBS graft polymerization technology and transformed it into industrial production. The products are always in the lead in our country. What is more, our company make good use of advanced technology and has pushed out MBS series, among which, M-51 has been listed 1995 annual national grade key new products; M-338 has won the support from the innovation funds of the State Science and Technology Ministry, and also listed national grade Torch Plan project of the year of 2001. MBS series have been tested to belong to non-toxic products and are suitable for food and medicine packaging.
    MBS resin needs to use different types as different usages due to their different compositions. After many years research, our company has successfully empolded M-51A, M-22 and M-338, and is a MBS manufacturer with the largest output.
