* Thermolite 140 butyltin mercaptide heat stabilizer is designed for PVC formulations for coextruded siding, profile, and fence substrates, and for pipe applications in which good early color and dynamic stability are important.
To prepare mercaptide-polymer blends, the mercaptide powder was dissolved or dispersed in chloroform and mixed with a chloroform solution of polystyrene (Aldrich, [M.sub.w] = 230,000 g/mol).
These new grades of alkyl tin mercaptide stabilizers eliminate the chatter, or vibrations, that occur when an extrusion line is running at high speed.
Available in liquid or solid form, either mercaptide or sulfur-free, products include butyltins for pipe, siding, window profiles and other applications; as well as octyltin mercaptide and methyltin mercaptides for FDA bottles and sheet.
