PAMS Resin Poly Alpha Methyl Styrene Resin

PAMS Resin Poly Alpha Methyl Styrene Resin

The Alpha Methyl Styrene resin is the monomer petroleum resin obtained by the copolymerization of α-methyl styrene and the second monomer. AMS Resin is a water-white, transparent, low-molecular-weight thermoplastic resin with a softening point of 80–150 °C. Compatible with numerous polymers, it lowers processing temperatures by 15–20 °C while markedly improving peel strength, hardness, and aging resistance. Low-odor and low-VOC, it is widely used for tackifying, reinforcing, modifying, and eco-friendly formulations.
