HydroThane is a hydrophilic thermoplastic polyurethane elastomer, ranging in water absorption rates from 5% to 25%. This unique extrudable hydrophilic product line was designed to provide maximum physical properties for use in extruded or injection molded components, while allowing for consistent single-step surface lubricity characteristics and a low coefficient of friction.
Available in aliphatic and aromatic versions, these elastomers have the ability to rapidly absorb water while maintaining high tensile strength and high elongation, resulting in a permanently lubricious polymer.
HydroThane can be processed using conventional extrusion or injection molding equipment.
Being hydrophilic even when dehydrated, they should be sealed and stored in a cool, dry place and are available in hardnesses of 80 Shore A and 93 Shore A.

HydroThane processing can be optimized by drying to a moisture content equal to or less than 0.05% by weight prior to melt processing.
Typically, the pellets must be dried for 3-4 hours with a dryer inlet air temperature of 180ºF +/- 20ºF. We recommend a machine-mounted desiccant-type hopper dryer, capable of reaching and maintaining a dew point of -40ºF. If dry times are in excess of 8-10 hours, a hopper dryer temperature of 120-150ºF is usually sufficient to achieve optimal moisture content.
