The application of MBS impact modifier  in PVC film has significant advantages, including improving the impact resistance and processing flowability of PVC film while maintaining material transparency. MBS is a high-performance material composed of methyl methacrylate, butadiene, and styrene copolymer, and its unique core-shell structure endows it with excellent modification ability.

MBS impact modifier can significantly improve the impact resistance of PVC film. Due to the core-shell structure of MBS resin, the butadiene core can absorb and disperse energy when subjected to external impact, effectively preventing brittle fracture of the material. This impact resistance is particularly important for the production of PVC films that require high strength and toughness, such as cling film and decorative film.

MBS impact modifier can significantly improve the cold resistance and processing flowability of PVC film. Under low temperature conditions, PVC films with added MBS resin can still maintain good toughness and are not easily brittle or broken, providing a guarantee for their application in refrigerated environments. And MBS can also improve the processing plasticization performance of PVC materials, reduce energy consumption and time in the production process, and improve production efficiency.

MBS impact modifier can enhance PVC film while maintaining its high transparency. Due to the similar refractive index of MBS and PVC, the blending of the two can achieve a uniform refractive index without affecting the transparency of PVC film. This characteristic makes MBS the preferred material for manufacturing transparent PVC films, widely used in fields such as food packaging and medical devices.
