Baerostab OM 36

Octyl tin mercaptopropionate. Acts as a heat stabilizer or as co-stabilizer (booster) in combination with liquid tin or Cd- and Pb-free mixed metal stabilizers. It is a very powerful PVC stabilizer. It is particularly recommended for the stabilization of rigid PVC and its alloys with other thermoplastic polymers where superior mechanical properties and high heat distortion temperatures of the finished product are of primary importance. Transparent as well as pigmented articles with a Vicat temperature above 80 °C can be extruded or molded with low addition levels of Baerostab OM 36. It is particularly suitable for the calendering of sheets which require a very good printability, also after storage of the sheets, e.g. sheets for credit cards. Its dosage rate is 0.7-1.2 phr.
