1. General principles of polymer stabilization
The basic principle of polymer stabilization is to maintain the initial properties - mainly aesthetic and mechanical - of a polymer during manufacture, storage, processing and throughout its existence as a finished object, with the aid of carefully selected additives.

Statistical and economic data
It is particularly difficult to get a clear picture of the market for stabilizers used in plastics, as the notion of stabilization can take on multiple definitions, and the market often considers additives (modifiers) as a whole, not just stabilizers. Of all polymers, PVC (polyvinyl chloride), which is not discussed here, is the one with the highest stabilizer volume [
