What is the purpose of Impact Modifier MBS resin?

📝 Product Overview

MBS resin (methyl methacrylate-butadiene-styrene copolymer) is a professional-grade polymer impact modifier featuring an innovative “core-shell” structure design. Its core, based on elastic butadiene rubber, delivers exceptional toughness protection; while its shell utilizes a methyl methacrylate/styrene copolymer to ensure perfect compatibility with polar substrates like PVC.

Core Value:

→ 🛡️ Exceptional Toughness: Significantly enhances product impact resistance, particularly excelling in low-temperature environments

→ 🔍 Crystal-Clear Transparency: Refractive index highly matched to PVC (≈1.534), preserving original product clarity

→ ⚙️ Smooth Processing: Excellent flow and dispersion properties simplify production workflows

→ ✅ Safe & Reliable: Complies with food contact material standards, ensuring safe use in packaging applications
