Nouryon is a global supplier of organic peroxide initiators to the PVC industry. We are also a global leader in secondary suspending agents which are used to control porosity in PVC polymers.

Ethapol®, DCloud®, Active® Suspending Agents

We offer a wide range of secondary suspending agents, which are used to control PVC porosity. This includes solvent-based products and aqueous emulsions. We are home to the best known brands in the business: Ethapol, DCloud and Active. Our water-based suspending agent emulsions can also be used for hot charge PVC technology, which provides excellent PVC characteristics and reduced fish eye levels in combination with organic peroxide emulsions.

Ethapol MPG is a secondary PVA, which also has antifoaming properties. Antifoaming agents are essential for good PVC reactor performance. They prevent foaming in both the reactor and PVC stripping sections. Ethapol 1000 is an acrylic copolymer powder and is mainly used in styrene suspension polymerization. 


Innovation is at the core of our business. We are a global leader in secondary suspending agents and are determined to maintain our status. A key part of our business depends on developing innovative new products and technologies for our customers.
