Supplier for the PVC industry

We are a global supplier of organic peroxide initiators, antifouling and secondary suspending agents to the PVC industry.

Polyvinyl chloride (PVC) is produced through the polymerization of vinyl chloride monomer (VCM) with the help of an organic peroxide initiator. We are the largest global producer of polymerization initiators. Our Trigonox^®, Perkadox^® and Laurox^® brands are well-known.

Our Noxol^® and Everplus® antifouling agents, prevent reactor fouling and polymer build-up in suspension PVC processes, which can reduce heat transfer and product quality. In addition, they provide savings in operational costs and time by increasing the number of batches without need for cleaning.

We offer a wide range of polyvinyl alcohol (PVA) secondary suspending agents, which are used to control PVC porosity and to improve drying and stripping.
