Alpha Methyl Styrene (AMS)
European-origin Alpha Methyl Styrene, a dependable reactive monomer for adhesive and sealant formulation and flexible-PVC and plasticizer use, supplied to US ports with full certificates of analysis.
Overview
Alpha Methyl Styrene (AMS) is drawn from established EU production and shipped to US ports as full-container loads. It serves adhesive and sealant formulation, flexible-PVC and plasticizer use, and reactive (UV/EB-curable) systems for formulators across North America.
All material moves with a full certificate of analysis, and the material is TSCA-listed for straightforward customs clearance. Standard supply is ISO tank or drummed ocean freight into Charleston, New Orleans, and Los Angeles/Long Beach, with tote and drum options for warehouse-ready delivery. It moves as a regulated flammable liquid, so we coordinate compliant hazmat documentation and packaging on every order.
