Plasticised Polyvinyl Chloride - Plasticised PVC - PPVC >300% Elongation.

Sep 7 2001

Polymer Type

Thermoplastic

Advantages

Very soft and flexible, high elongation to break and low melt viscosity compared with PVC with lower levels of plasticisation.

Disadvantages

Poor flammability characteristics, very low tensile strength and modulus compared with PVC with lower levels of plasticisation.
