POLYOX™ WSR 303

POLYOX™ WSR 303 is a water-soluble poly(ethylene oxide) polymer. It is used as a binder in ceramics and as an additive to reduce frictional drag of water.
Product Overview
POLYOX™ WSR 303 is a non-ionic, water soluble poly(ethylene oxide) polymer with a molecular weight of 7,000,000. POLYOX™ WSR 303 works well as a binder for ceramics application. It greatly improves green strength of ceramic parts and due to it's psedoplastic rheology extrusion pressure is dramatically decreased. POLYOX™ WSR 303 will also reduce the frictional drag of water by ~80% when used in very small volumes (5-200 PPM) making it an ideal additive for fire fighting and storm sewers.
