MBS Impact Modifier

Product Name: MBS Impact Modifier
Product Category: PVC Additive (Impact Modifier)
Chemical Nature: Ternary copolymer of methyl methacrylate (MMA), butadiene (BD) and styrene (ST) via emulsion polymerization, with typical “core-shell” structure
Core: Slightly cross-linked butadiene-styrene copolymer (rubber elastomer)
Shell: MMA-styrene copolymer (good compatibility with PVC)
Main Component: Methyl Methacrylate-Butadiene-Styrene Copolymer
Additional Product Features:
Enhances PVC impact strength significantly with low addition levels
Good compatibility with PVC; improves melt strength and surface finish of PVC products
Non-transparent Type: Excellent dimensional stability (low die swell rate); suitable for rigid PVC products
Transparent Type: High light transmittance, low haze and low whitening on folding; suitable for clear PVC products
Recommended Uses:
Non-transparent Type: PVC pipes, fittings, non-transparent films/sheets, card bases
Transparent Type: PVC transparent films/sheets, clear containers, medical packaging, transparent pipes
Packaging Specifications: Kraft paper bags with inner plastic liners, net weight 20kg/bag; customizable packaging available upon customer request
