The main performance of MBS Impact Modifier and its application
The main performance of MBS impact modifier and its application
MBS (Methylmetharylate-Butadiene- Styrene) is a new kind of polymer material synthesized under the concept of particle design. Methyl methacrylate (M), butadiene (B) and styrene (S) are produced
by emulsion graft polymerization.
In the sub-micro-morphology has a typical core shell structure, the core is a diameter of 10nm-100nm rubber phase spherical nucleus, the outside is composed of styrene and methyl methacrylate shell.
Due to the dissolution parameters of methyl methacrylate and polyvinyl chloride (PVC), it acts as an
interfacial adhesive between PVC resin and rubber particles, and is homogeneous in the process of mixing with
PVC Products with excellent impact resistance. When the PVC by adding 5% -10% of the MBS resin, the impact of the product can improve the strength of 4 times -15 times, but also improve the product's cold resistance and
processing fluidity, the refractive index and PVC similar to MBS
PVC impact modifier does not affect the transparency of PVC. MBS is the best material to improve
PVC impact resistance, making transparent products, and almost all of the transparent PVC products use it as an impact modifier. Therefore, MBS resin as PVC resin impact modifier has a wide range of applications.
MBS impact modifier main performance
MBS impact modifier has excellent transparency, good wear resistance, coloring and more general low temperature characteristics. Its refractive index and PVC is similar, is used for PVC modified to create the best materials for transparent products. In general, MBS has a suitable compatibility with PVC blends, and the stability of the blends is improved. MBS glass transition temperature is relatively low, it can in a certain low temperature limit to enhance the impact resistance of PVC. Improve the toughness of PVC and processing performance is another important feature of MBS, that is, to improve the friction to promote PVC particles disintegration and further gelation, shorten the melting time, reduce material retention time, to prevent decomposition, and ultimately improve the processing performance.
