Phenolic Resin for Exterior Insulation Board
The resin uses melamine and resorcinol double modification technology to control the high ortho structure and methylol concentration of phenolic resin, and develops a phenolic resin with a foaming process similar to polyurethane foaming. The resin is at a certain temperature. Foaming also has obvious emulsification time, foam rise time, gel time, and curing time. It has achieved a revolutionary breakthrough in the foam production process, and can be used in the production line of continuous phenolic foam boards. The produced foam has the advantages of good dimensional stability, fine foam and low thermal conductivity.
The Main Purpose： The resin can be used for continuous molding process to produce phenolic foam insulation board.
