Use of mono- and disubstituted organotins in PVC

Additionally, plastisol ( paste ) type PVC compounds are in the form of a thick paste that can be applied by techniques such as coating, dipping, or rotational moulding. 

Over 90% of organotin stabilizers are used in rigid PVC. Table 3 provides details of the estimated quantities of methyl-, butyl-, and octyltin stabilizers used in rigid and flexible PVC applications, whereas Table 4 details the types of applications in which the PVC products are used. 

From ESPA (2002). Note that figures are based on percentages and have not been rounded. 

Industry estimates suggest that, for the two major uses — packaging and rigid construction, accounting for over 85% of use — the products in question are produced at 55 PVC processing plants across the EU. For all uses, there are estimated to be 130 major plants and a further 250 smaller users, spread fairly evenly across the EU (ESPA, 2002). 

PVC is the only plastic in which organotin stabilizers are used. The total European market for PVC is
