PVC polymer chlorination with LEDs enhances resin stability

Summary
Lubrizol has begun producing CPVC using LED-lit chlorination reactors instead of mercury lamps. The shift improves the resin’s thermal stability—enabling longer extrusion runs and more complex molds—while also lowering process energy costs.

What impacts do you expect LED-based photochemistry to have on broader CPVC manufacturing—are the stability gains and energy savings enough to accelerate industry-wide replacement of mercury-lamp systems?

Lubrizol (Cleveland, Ohio) recently began producing chlorinated polyvinyl chloride (CPVC) resin in commercial reactors equipped with light-emitting diodes (LEDs) as the light source, instead of the conventional mercury lamps. The company’s LED reactor technology enhances the thermal stability of the product resin, allowing users of the resin the ability to run extrusion processes longer and to undertake more complex molds. The LEDs also reduce process energy costs.
