Dioctyl(maleate)tin

Dioctyltin maleate (CAS 16091-18-2) is a highly effective heat stabilizer for PVC, especially suitable for high-grade transparent shrink films, cigarette films, and other rigid transparent products. It offers excellent long-term thermal and light stability and exhibits a synergistic effect when used in combination with thiol-based dioctyltin compounds, with a typical dosage of 0.5-3%. It is also used as a crosslinking catalyst for silicone rubber and as an additive in polyurethane systems, improving the storage stability of adhesives and extending the service life of plastics. It is suitable for high-end packaging and industrial applications.
