AM Stabilizers is committed to providing the market with products that will meet ever increasing regulatory demands. The initiatives driving the current technologies including Prop 65, REACH, RoHs, CONEG, etc. are narrowing the scope of allowable chemistries.  Being a global supplier of intermediates and additives provides AM Stabilizers with the unique advantage of staying ahead of the curve in the constantly changing, regulatory climate today and long into the future.
