Description

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

One of the advantages of W5B is its low residue, which means that it can be used in applications where low levels of residual monomers or other impurities are desired. Additionally, the glycidyl ester functional group provides W5B with reactive sites that can be used for various functionalization reactions, such as cross-linking or modification with other chemicals.

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.
