Description

 

Product Overview

POE-g-GMA is a high-performance functional polymer based on polyolefin elastomer (POE) grafted with glycidyl methacrylate (GMA) functional groups through advanced grafting technology.

By combining the excellent elastomeric toughness of POE with the high chemical reactivity of epoxy groups from GMA, POE-g-GMA provides outstanding interfacial adhesion, impact modification, and compatibility improvement in polymer blend systems.

It is specially designed for improving the performance of:

• PET modification
• PBT modification
• PC/PBT alloy systems
• PET/PC blends
• PP/PBT polymer alloys
• Glass fiber reinforced engineering plastics
• Flame retardant polymer compounds

Key Features & Advantages

1. High Epoxy Functional Group Content for Superior Compatibility

AOSILE-W5AS features a high GMA grafting level, with epoxy functional group content:

1.5–4.0 wt% (Extra High Grade)

The highly reactive epoxy groups can chemically react with functional end groups in:

• PET (Polyethylene Terephthalate)
• PBT (Polybutylene Terephthalate)
• PC (Polycarbonate)

including:

• Carboxyl groups (-COOH)
• Hydroxyl groups (-OH)

This significantly improves the interface bonding between different polymers.

Suitable for demanding applications including:

• High filler loading compounds
• Glass fiber reinforced plastics
• Polymer alloy systems
• High-performance engineering plastics

2. Excellent Toughening Performance for Polyester Materials

The POE elastomer phase provides outstanding energy absorption capability, effectively improving:

• Notched impact strength
• Low-temperature toughness
• Crack resistance
• Mechanical durability

Recommended for:

• PBT impact modification
• PET toughening
• PLA toughness improvement
• Glass fiber reinforced PBT/PET systems
• Flame retardant engineering plastics

Typical addition level:3–5%

can significantly improve impact performance while maintaining processing stability.

3. Reactive Compatibilizer for Polymer Alloy Systems

POE-g-GMA works as a reactive compatibilizer to improve the compatibility between non-polar polyolefins and polar engineering plastics.

It effectively solves common problems such as:

• Poor interfacial adhesion
