Plasticisers are low-molecular-weight polymers that increase the spacing between chains of crystalline polymer to make them more flexible and, thereby, tougher.

What is plasticiser made of?

What are they made of? Plasticizers are produced by a reaction of an alcohol with an acid such as adipic acid, phthalic anhydride, and so forth. The choice of alcohol and acid will determine the type of ester that can be produced and hence the kind of plasticizer.

Which one is a plasticizer?

Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world's most widely used PVC plasticizer. DINP, DIDP: High molecular weight ortho-phthalates.
