Grafted Polymers
Compatibilizer Supplier
Compatibilizer Series
As a compatibilizer supplier, SYCHEM TECH produces SY series compatibilizers — maleic anhydride (MAH) grafted polymers engineered to bridge the gap between immiscible polymer systems. By enhancing interfacial adhesion between the matrix resin and fillers, fibers, or alloy components, they deliver measurable improvements in tensile strength, impact resistance, and surface quality — critical for automotive, appliance, and industrial compounding applications.
