Organotin PVC stabilizers remain irreplaceable for medical and food packaging applications, offering a unique balance of safety, clarity, and performance that no other stabilizer class can match. While alternatives like Ca/Zn systems continue to improve, they still cannot match methyl tin’s transparency and long-run stability in demanding calendering and extrusion processes.
Modern food-contact regulations across the EU, U.S., and Asia require stabilizers that not only perform technically but also comply with strict migration limits. Methyl tin mercaptides, when properly formulated, meet these requirements while delivering processing efficiency that reduces scrap rates and energy consumption.
Unistars supplies ROHS-compliant, food-contact-grade stabilizers (XY-728, XT-188) that help packaging manufacturers access high-margin markets with confidence. Our technical team provides lab-tailored formulations for your specific application.
