High-Performance MBS Impact Modifiers for PVC - China Suppliers & Factory
Product Characteristics
Impact Modifier MBS
Impact resistant MBS resin is mainly used in the PVC processing and forming process to improve its impact strength without damaging the inherent characteristics of PVC. Due to its similar solubility parameters to PVC, the two have good thermodynamic compatibility, manifested as PVC having high impact strength, temperature resistance, and coloring properties at room or low temperatures.
Transparent Modifier MBS
Transparent MBS resin is mainly used in the processing and forming of transparent PVC products, to improve their impact strength without damaging the inherent characteristics of transparent PVC products. Its refractive index is similar to PVC, and using MBS as a PVC impact modifier will not affect the transparency of PVC. It is the best material for improving the impact resistance of PVC and manufacturing transparent products.
Competitive Advantage
Compared with other companies, our MBS has higher impact resistance, better compatibility, and wear resistance, delivering superior durability and visual clarity for your end applications.

Frequently Asked Questions
What are the primary applications of MBS impact modifiers?
MBS impact modifiers are primarily used during PVC processing to enhance the material's impact strength without compromising its inherent features, such as room or low-temperature resistance and coloring properties.
Will using MBS modifiers affect the transparency of PVC?
No. The refractive index of our transparent MBS modifier is very close to that of PVC. Therefore, integrating MBS as an impact modifier preserves the original transparency of the PVC products.
What advantages does your MBS offer compared to other brands?
Our MBS modifiers offer superior impact resistance, enhanced thermodynamic compatibility, and excellent wear resistance compared to alternative options on the market.
What is the physical form of the BLD-56 and BLD-518 MBS series?
Both the BLD-56 (including 561, 562, and 564) and BLD-518 (including 528 and 568) series are supplied as free-flowing white powders with a 30 target sieve pass rate of ≥98%.
What are the glass transition temperatures for these MBS grades?
The glass transition temperature for the BLD-56 series is -72.5±1.0 °C, whereas the BLD-518/528/568 series has a glass transition temperature of -62.5±1.0 °C.
What is the volatile matter limit for these modifiers?
Both the BLD-56 and BLD-518 series maintain a volatile matter specification of ≤1.0% to ensure high stability during processing.
