Introduction

1. Definition of Plasticizer

Plasticizer is material incorporated in a PVC resin to increase its workability, flexibility (lower melt viscosity, temperature of TG or elastic modulus of plastic).

Therefore the selection of optimum plasticizer affects the successful use of PVC in many diverse applications.

 

2. Function of plasticizer

Process Aid
  • Lower hot melt viscosity
  • Resin stability
  • Reduced sticking of resin
  • Increase internal lubricity
  • Increase tensile strength
  • Lower the processing temperature
  • Reduce sticking in mold
End-use Plasticizer
  • Softening to the resin
  • Increase elongation
  • Increase Flexibility
  • Increase impact resistance
  • Increase tear strength
  • Increase the temp. range of usefulness
  • Increase toughness
