Polyurethane Foam Chemical Kit, Excellent demonstration of thermoplastic polymers, Each

Details

Produce polyurethane foam with the condensation reaction of a polyisocyanate and a hydroxyl-containing material (i.e., a polyol derived from propylene oxide).Mix two viscous liquids to initiate a reactionLightweight foam expands to 30 times the original volume of the liquidsAfter about 10 minutes, the foam hardensPerform in a fume hood and wear chemical splash goggles, apron and gloves as the chemical components are eye and skin irritants.
