Batch Foaming Machines and the Supreme Efficiency
PU foams are a result of the reaction that occurs between a polyol and an isocyanate prepolymer. A blowing agent and a catalyst (in the form of amine) are also included in the reaction. In this case, the isocyanate acts as a diisocyanate. For instance, you can use toluene diisocyanate or methylene diphenyl diisocyanate.
A Batch Foaming Machine is used to let this reaction happen so that it can form high-strength and highly flexible blocks of foam with a single block at a time. Fortunately, these machines are quite affordable even though they provide low quantities.
