EXAHARD® is a range of medium viscosity polymer polyols specially designed to increase the hardness of flexible polyurethane foams. These are polyether polyols made with a UNIQUE FRENCH TECHNOLOGY based on different copolymers together with high functionality polyols. They allow improving hardness of foam and its production cost while maintaining good physical properties.

1. High increase in the hardness of foam
2. Reduction of manufacturing cost by lowering the TDI index and/or foam density
EXAHARD® range is conditioned in drums of 250kg.
