Continuous processors quickly mix fast-reacting materials

By Chemical Engineering |

Readco Kurimoto

This company’s Continuous Processors (photo) feature a proprietary design that ensures the fast-reacting materials used to process rigid polymeric foams are mixed, gelled and reacted entirely within the sealed reactor barrel before they begin to cure. Allowing foam formation and curing to occur entirely downstream, the Continuous Processors eliminate the risk of premature curing inside the barrel, along with its requisite, labor-intensive cleaning and safety concerns. Developed for producing foams, such as polyurethane, polystyrene, polyethylene and other materials that cure instantaneously, the Continuous Processors strategically introduce isocyanates, blowing agents and other reactants at key points in the process to efficiently produce a uniform, homogeneous dispersion of materials within a tight residence time. Targeted specifications for strength, cell morphology, thermal conductivity and other properties are consistently achieved. — Readco Kurimoto, LLC, York, Pa.
