A substance (typically a solvent) added to a synthetic resin to promote plasticity and to reduce brittleness
A plasticiser is an additive used with PVC in order to improve the flexibility or the process characteristics of a thermoplastic or an elastomer They are oil-like, high boiling point liquids with good thermal stability The most common ones are based on organic esters e g phthalates, adipates and trimellitates
A chemical added to another material to give it increased flexibility In some plastics such as PVC, plasticisers leach out in time and leave the material brittle Adhesives for use in preservation should be 'internally plasticised'
a substance of low or negligible volatility incorporated in a plastic to lower its softening range and to increase its workability, flexibility or extensibility
{i} substance added to plastics or other materials to give it pliability and reduce fragileness (also plasticizer)
