MBS impact modifier is the tercopolymer of methyl methacrylate(M), butadiene(B),styrene(S) , mainly used in the process of rigid PVC，the main characteristics of is that it offers PVC products with high impact resistance, high transparency, good processability and reduced gelation time and less crease-whitening.

Improving impact resistance: MBS impact modifier can significantly enhance the impact resistance of PVC fittings, making them less prone to breakage when subjected to external forces or impacts, ensuring safe use.

Improving toughness: Adding MBS can enhance the toughness of PVC fittings, reduce brittleness, adapt to a wider range of temperature changes and mechanical stresses, and extend product service life.

Enhance weather resistance: MBS can improve the UV and weather resistance of PVC fittings, making them less prone to aging and discoloration when used outdoors, and maintaining their appearance and performance.

Improving processing performance: The addition of MBS can improve the processing fluidity of PVC accessories, making the molding and extrusion processes smoother, reducing the scrap rate in the production process, and improving production efficiency.

Improving appearance quality: MBS can increase the surface smoothness and glossiness of PVC accessories, making the final product more aesthetically pleasing and meeting the market's demand for high-quality products.
