INTRODUCTION TO PARC

The product application and research center PARC (Reliance Industries Limited petrochemical division was established in 1990 at Chembur, Mumbai as a technical wing of the polymer marketing division. It is deeply involved in the development of new grades & the optimization of the existing grades in terms of cost & properties.

PARTIAL REPLACEMENT OF DI OCTYL PHTHALATE (DOP) PLASTICIZER WITH TRIACETINE

WHY TO REPLACE DOP….???

• change hormone levels and cause birth defects•Adverse effect on physical growth

FORMULATION

All formulations are in PHR

COMPOUNDING

•Add PVC + GMS + Stearic acid and start the mixer•After 5 min. add octyl tin stabilizer.•Then add half amount of plasticizer, when mixer temperature reaches to 650C.•When temperature reach once again to 650C then add remaining amount of plasticizers.•At 800C remove the material from the mixer and allow it to cool .

EXTRUSION

COMPRESSION MOULDING.

SAMPLE PREPARATION.

HEAT AGING.

TESTING

HEAT AGEING :

Tensile specimen before and after heat aging

DENSITY

RESULTS AND DISCUSSION

TENSILE STRNGTH

ELONGATION

• It can be clearly seen that, As the concentration of triacetin increases, density increases respectively.

•Triacetin increases Tensile Strength and elongation at break .

• Increase in content of Triacetin increases hardness.

•So on basis of above all results we can conclude that Triacetin plasticizer is not suitable for complete replacement with DOP plasticizer but it can use a partial replacement with DOP plasticizer thus can be used where short shelf life of product is required.
