Organo Tin Stabilisers
Organo tin stabilisers are the most universally applicable stabilisers due to their high effectiveness and high degree of transparency. Tin stabilisers are used in all types of PVC today, including suspension, emulsion and mass-polymerised grades, and they find applications in the most demanding rigid PVC and flexible PVC manufacturing processes.
Organo tin stabilisers are always based on Methyl, Butyl or Octyl groups. Organo tin mercaptides are sulphur-containing products. They are the most efficient heat stabilisers and offer excellent early colour and colour hold at very low dosages. Sulphur-free Organo tin carboxylates such as tin maleates, although less efficient than tin mercaptide during processing, offer excellent light and weather resistance to finished goods for outdoor applications.
