Polyethylene oxide thickener. Molecular Weight 4,000,000 Yields viscosity of 1,650 to 5,500 cP at very low addition levels.


Product Overview

POLYOX™ WSR 301 is a water-soluble resin. It is based on a long chain nonionic polyethylene oxide polymer. The product has a high molecular weight of 4,000,000 with a viscosity of 1650 - 5500 cP.


POLYOX™ WSR 301 works as a thickener, binder, film former, lubricant, and water retention aid. It is widely used in ceramics, industrial cleaning products, electronics, mining, paper, adhesives, building, and construction.

  • Adhesives: POLYOX™ WSR 301 acts as a binder that provides a wet tack and dry release to adhesive formulations. The product features low toxicity that makes it perfect for consumer products.

  • Building and Construction: POLYOX™ WSR 301 is one of the best thickeners and binders for cement, mortars, and concrete applications. It provides aqueous thickening which improves the workability of cement and mortars. It also enhances lubricity and the pumpability of concrete at a low addition level.

  • Ceramics: POLYOX™ WSR 301 acts as a binder, forming aid and lubricant in the manufacturing of ceramic parts, bricks, fibers, and it also aids ceramic extrusion processes.

  • Cleaners: POLYOX™ WSR 301 exhibits emollient properties in cleaning solutions. It is used as a thickener, rheology modifier and application in aid in industrial and consumer cleaners.

  • Electronics: POLYOX™ WSR 301 provides improved binding properties that are utilized in fluorescent lighting, battery electrodes, energy storage devices. It also provides enhanced lubricity in cable lubricants and optical fibers applications.

  • Pulp and Paper: POLYOX™ WSR 301 is a high molecular weight flocculant that makes it perfect for retention and drainage aid in paper and tissue production. It can be used to boost the performance of traditional flocculants in the papermaking processes.

  • Water Treatment and Mining: POLYOX™ WSR 301 is a high-efficiency flocculant for clay, silica, oxidized coal fines and heavy metal. It facilitates the separation of difficult impurities and it also improves dust suppression and dewatering efficiency.
