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.

Di-Octyl Phthalate(DOP) is the most popular plasticizer in the world and also provide the most desirable combination of performance, characteristics and low cost of any plasticizer family used in Vinyl resins

2. FUNCTION OF PLASTICIZER

Process Aid

Lower hot melt viscosity
Resin stability
Reduced sticking of resin
Increase internal lubricity

Increase Flexibility
Increase impact resistance
Increase tear strength
Increase the temp. range of usefulness
Increase toughness
