Resistance to weather & adverse conditions is a key requirement & property of profiles, especially window profiles. Over the last decades, Lead based stabilizers window profiles have proven their outstanding durability under different climatic conditions. Profiles have maintained their mechanical properties, such as impact strength or dimensional stability. Even when exposed to solar radiation and subjected to alternate periods of humid and dry weather, they have proven their sustainability.

Though Calcium/Zinc stabilizers exhibit better color hold than traditional Lead systems both in artificial and natural weathering and the demand for Calcium/Zinc stabilizers is vastly growing, Lead stabilizers are still used because of their large processing latitude and outstanding heat stability. Vinyl Chemicals is in the process of developing Calcium/Zinc stabilizers that will offer good performance at considerably lower addition levels than Lead stabilizers.

Vinyl’s product range offers heat stabilizers which are widely used for stabilizing PVC. It is a stable chemical doesn’t decompose even at very high temperatures. It is an excellent stabilizer for both Rigid & Flexible applications, where long-term heat stability is required.
