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.Application case 1
