Expand Student Knowledge of Polymers
- The perfect supplement to your chemistry lectures
- Comes with enough chemicals to perform each demonstration five to seven times
- Can be performed in just 10–30 minutes
- Requires only basic labware that you provide
Ideal for illustrating foam and polymer production, as well as the use of catalysts in reactions, this dramatic demonstration will cause foam to grow 30 times the original volume of the reactants - a polyether polyol and a polyfunctional isocyanate. Use of a hood with adequate ventilation is recommended for this experiment.
