Description

W5B is a graft polymer containing glycidyl ester functional group, polyolefin elastomer as matrix material, high reactivity and low residue.

Performance comparison of W5B and imported polyester tougheners in PBT toughening

It can be seen from the above table that adding 4% W5B in the PBT flame retardant reinforcement system can improve the notched impact strength and preserve other properties well. It shows that W5B has superior processing performance in PBT flame retardant reinforcement system and can help glass fiber and flame retardant to disperse uniformly.

Characterisitic

W5B is suitable for produces which needs high reactivity and low residue.

Applications

1. Compatibilizer for polyolefin and polyester alloys
2. Used for PBT/PET enhanced filling, low temperature toughening modification
