plasticiser
A plasticiser is a substance added to a polymer to increase its flexibility, workability, and durability. By embedding between polymer chains, it reduces intermolecular forces and increases free volume, lowering the polymer's glass transition temperature and improving pliability and processability. Plasticisers are typically liquids or low-melting solids and are partially compatible with the host polymer.
Common plasticisers include phthalates (such as di(2-ethylhexyl) phthalate, DEHP), adipates (di(2-ethylhexyl) adipate, DEHA), and citrates (acetyl
Applications are dominated by vinyl polymers, especially PVC, where plasticisers enable flexible films, cables insulation, flooring,
Regulatory and safety aspects: some plasticisers can migrate from products and pose health risks, particularly for
