Insulation Rock Wool Material
Rock wool products are made of high-quality natural basalt ore and dolomite as the main raw materials. They are melted at high temperature, spun into fibers by high-speed centrifugal spinning, and then heat-cured and shaped using advanced production technology and a small amount of binder. The outer surface can be covered with glass fiber cloth or aluminum foil glass fiber cloth according to customer needs. The material varieties include plates, profiles, and tube shells.
Overview
Insulation rock wool material is mainly used for fireproofing and heat insulation of ship decks and bulkheads, pipelines, and equipment, and can also be used as a sandwich material for composite rock wool sidings/floating floors.
