Polyurethanes

Polyurethanes are used in many products and processes, from high-resilience foam seating, rigid foam insulation panels, microcellular foam seals/gaskets, coatings, durable elastomeric wheels, golf balls, tires, roller coaster wheels, shopping cart wheels, elevator bushings, skateboard wheels, automotive suspension bushings, electrical potting compounds, high-performance adhesives, surface coatings, and sealants. Polyurethane can be found almost everywhere, and SpeedMixing has been a valuable tool in Polyurethane mixing for years.

Problem: Moisture Sensitivity.

Solution: Polyurethane materials are moisture sensitive. Vacuum degassing polyols and isocyanates prior to mixing them together can help ensure that the formulation will be moisture and air-free. Introducing air bubbles can cause moisture contamination during the curing process. SpeedMixing’s non-invasive mixing technology delivers bubble free mixing compared to stir blades, wood stir sticks and spatulas which all introduce air.

Problem: Difficulty Incorporating / Homogenizing fillers

Solution: Fillers such as fumed silica, micro balloons, carbon black, conductive material and bond-line control beads can be extremely difficult to incorporate and homogeneously disperse into urethanes. Many common fillers can introduce moisture to urethanes. Staging materials in vacuum ovens the night before formulation work can be eliminated with minutes of vacuum SpeedMixing, eliminating the need to precondition or dry your fillers before mixing.
