PVC Plastisol Formulation for Molding
Budget: ₹12,500 – ₹37,500 INR
I’m developing a PVC plastisol specifically for molding applications and need technical guidance to arrive at a reliable, repeatable compound that delivers protective performance once cured. The finished parts must exhibit a balanced trio of properties—excellent heat resistance, strong chemical resistance, and good flexibility—without compromising flow or demold characteristics.
What I have: general lab-scale mixers, heating baths, standard plastisol raw materials, and access to common analytical tests (Shore hardness, tensile, aging).
What I need from you:
• A full formulation blueprint (resin grade, plasticizer package, stabiliser system, fillers, pigments, viscosity modifiers, etc.) that satisfies the property targets above.
• Clear processing parameters for both lab batches and scale-up: mixing order, temperatures, dwell times, deaeration, and recommended mold temperatures.
• A short validation plan outlining which ASTM/ISO tests to run for heat aging, chemical splash resistance, and flexibility so I can confirm the compound meets spec.
• Iterative adjustment advice after my first trial—two rounds of tweak-and-review to lock the recipe down.
Preference goes to professionals with hands-on PVC plastisol formulation experience and familiarity with additives from major suppliers (e.g., Eastman plasticizers, Baerlocher stabilisers, Cabot fillers). Please outline similar projects you’ve completed and your proposed timeline for initial deliverables.
