α-Methyl Styrene Monomer Resin (AMS Resin)
Product Overview
α-Methyl Styrene Monomer Resin is produced through cationic polymerization of α-methyl styrene with secondary monomers, resulting in a water-white resin with exceptional aromaticity and cohesive strength.
This versatile tackifying resin offers broad application potential across tire manufacturing, hot-melt adhesives, TPE modification, and plastic processing industries, with grades tailored for specific softening point requirements.
