Polyurethane phenolic composite air duct

Phenolic resin is the earliest industrialized plastic product in the world, and phenolic foam is a newly developed variety. Phenolic foam is known as the king of thermal insulation. It was early used in the insulation of missiles and rocket heads. It has become the fastest growing variety of plastics in some developed countries such as the United States, Britain, and Japan. Phenolic foam materials have good flame retardant properties, small thermal conductivity, excellent sound absorption properties and long service life. Because phenolic foam materials have the above superior properties, they have been widely used in various aspects of the national economy, such as central air conditioning ducts, hot and cold conveyance ducts, clean workshops_ b _ r />
