MBS Impact Modifier, also known as MBS resin, is a copolymer comprising methyl methacrylate, butadiene, and styrene. Its compatibility with PVC is remarkable due to a solubility parameter ranging from 94 to 95, closely matching that of PVC. MBS Impact Modifier can improve impact performance, tensile strength, elongation at break, transparency, and light transmittance, often exceeding 90%. However, it should be noted that this modifier exhibits limited heat resistance and weather resistance, making it less suitable for long-term outdoor applications.

Enhancing PVC Properties

In the realm of PVC product manufacturing, MBS Impact Modifier as a toughening agent with excellent transparency. Beyond enhancing impact resistance and promoting transparency, MBS Impact significantly improves processability. During the plasticizing process, MBS interacts with PVC by intertwining and rubbing against it. This interaction not only facilitates the disintegration of PVC particles but also forms strong bonds with PVC particles, promoting PVC gelation. As a result, the melting time is reduced, material residence time in the extruder decreases, and PVC decomposition is prevented, contributing to enhanced processability.

Expanding Applications

The applications of MBS resin are continually expanding, positioning it as a key modifier for engineering plastics. Our GM series products represent reinforced resins meticulously developed for engineering plastics, delivering substantial improvements in low-temperature strength and processability. They find widespread use in engineering plastics such as PC/ABS blends.
