Methyl methacrylate-Butadiene-Styrene Impact Modifier for PVC

MBS Impact Modifier

Methyl methacrylate-Butadiene-Styrene Impact Modifier for PVC

MBS(Methylmetharylate-Butadiene-Styrene) is a new polymer material.It has a typical core-shell structure and the core is a rubber phase spherical nucleus.The outside is a shell composed of styrene and methyl methacrylate.


Due to the similar dissolution parameters of methyl methacrylate and PVC, it plays the role of interface adhesive between PVC resin and rubber particles, and forms a homogeneous phase in the process of PVC processing and mixing, giving the product excellent impact resistance.

    PRODUCT INTRODUCTION

    When 5%-10% MBS resin is added to the production of PVC, the impact strength of the product can be increased by 4-15 times, and the cold resistance and processing fluidity of the product can also be improved perfectly.

    As the refractive index of MBS is similar to PVC, so it will not affect the transparency of PVC product to use MBS as impact modifier.

    MBS is a superior material for improving the impact resistance of PVC and manufacturing transparent PVC products, so it is a widely used PVC impact modifier in PVC industry and most of all transparent PVC products use it as the impact modifier. Therefore, MBS resin as an impact modifier for PVC industry has a wide range of application prospects.
