Plasticised Polyvinyl Chloride - Plasticised PVC - PPVC (0 - 100%) Elongation

Polymer Type

Thermoplastic

Advantages

Better tensile strength, modulus and flammability characteristics than PVC's with higher levels of plasticisation.

Disadvantages

Lower elongation at break and low temperature impact strength than PVC's with higher levels of plasticisation.
