Product Description

AC BLOWING AGENT Cyclopentane For EVA Injection Molding

Chemical blowing agents include isocyanate and water for polyurethane, azodicarbonamide for vinyl, hydrazine and other nitrogen-based materials for thermoplastic and elastomeric foams, and sodium bicarbonate for thermoplastic foams. Gaseous products and other byproducts are formed by a chemical reaction of the chemical blowing agent, promoted by the heat of the foam production process or a reacting polymer's exothermic heat. Since the blowing reaction occurs forming low molecular weight compounds acting as the blowing gas, additional exothermic heat is also released. Powdered titanium hydride is used as a foaming agent in the production of metal foams, as it decomposes to form hydrogen gas and titanium at elevated temperatures.Zirconium(II) hydride is used for the same purpose. Once formed the low molecular weight compounds will never revert to the original blowing agent; the reaction is irreversible.
