Description
🔹 Product Description:
AOSILE® W5G-3 is a high-performance SEBS grafted Glycidyl Methacrylate (GMA) functional polymer designed as a reactive compatibilizer, polymer toughening agent, and interfacial modifier for advanced polymer modification applications.
Based on a hydrogenated styrene-butadiene block copolymer (SEBS) backbone, W5G-3 introduces a high concentration of epoxy functional groups through GMA grafting technology. The reactive epoxy groups provide excellent chemical bonding capability with polymers containing hydroxyl and carboxyl groups, significantly improving compatibility, impact strength, and interface adhesion in polymer blends.
🔹 Typical Applications:
- PET and PBT toughening modification
- Polyester alloy compatibilization
- PP/PET polymer blend compatibility improvement
- Engineering plastic impact modification
- TPE overmolding adhesion enhancement
- Low-temperature toughening applications
