Zinnstabilisatoren

Zinnstabilisatoren, also known as tin stabilizers, are chemical compounds used in the production of PVC (polyvinyl chloride) to improve its thermal stability and processing properties. They are typically added to PVC formulations to prevent the formation of hydrochloric acid during the production process, which can lead to discoloration and degradation of the polymer. Zinnstabilisatoren work by reacting with the hydrochloric acid to form a stable compound, thereby preventing the acid from causing damage to the PVC.

The most commonly used Zinnstabilisatoren are organotin compounds, such as tributyltin oxide (TBT) and dibutyltin dilaurate (DBTDL). These compounds are effective in stabilizing PVC and improving its processing characteristics. However, due to environmental concerns and the potential toxicity of organotin compounds, there has been a shift towards the use of alternative stabilizers, such as calcium and barium-based compounds, which are considered to be more environmentally friendly.

Zinnstabilisatoren are essential in the production of PVC, as they ensure the polymer's stability and quality. They are widely used in various applications, including the manufacture of pipes, profiles, and films, as well as in the production of cables and electrical insulation. The choice of Zinnstabilisatoren depends on the specific requirements of the PVC formulation and the desired properties of the final product.
