Product Description

MBS impact modifier is a copolymer of methyl methacrylate, butadiene and styrene. The solubility parameter of MBS is 94-9.5, which is close to that of PVC. Therefore, MBS has good compatibility with PVC. Its biggest feature is that transparent products can be made by adding PVC. Generally, adding 10-17 phr of PVC can increase the impact strength of PVC by 6-15 times, but when MBS is more than 30 phr, the impact strength of PVC will decrease. MBS itself has good impact performance, good transparency, light transmittance up to more than 90%, and at the same time, it has little impact on other properties of the resin, such as tensile strength, elongation at break and so on. MBS has a high price and is often used in combination with other impact modifiers, such as EAV, CPE, SBS, etc. MBS has poor heat resistance and weather resistance, so it is not suitable for outdoor long-term use products. Generally, MBS is not used as impact modifier in the production of plastic door and window profiles.


MBS resin is a kind of core-shell copolymer which is grafted by MMA and dried by salting out. The modified PVC can improve its impact strength and comprehensive properties. Because of its similar refractive index with PVC, the modified PVC has better transparency, so it is widely used in transparent products. It is not suitable for outdoor products because it contains butadiene, which is easy to decompose and age when exposed to light.MBS can not only give good toughening effect and excellent transmittance of hard PVC, but also improve its processability, because MBS intertwined PVC in the plasticizing process and rubbed each other, which not only promoted the disintegration of PVC particles, but also bonded with PVC particles, which promoted the gelation of PVC. Therefore, the melting time is shortened, the residence time of the material in the extruder is reduced, the decomposition of PVC is prevented, and the processability of PVC is improved.
