Kingflex rock wool insulation pipe is produced with natural basalt as main material, melted in high temperature and made into artificial abio-fibers by high speed centifugal equipment, then added with special agglomerates and dustproof oil, heated and solidified into various rock wool heat preservation products in different specifications according to different requirements. Kingflex rock wool insulation pipe have many advantages such as light weight, good performance as a whole and low coefficient of heat conductivity. They are widly used in construction and other inductries in heat preservation field. It also has a good function of sound absorption, so it can be used to reduce the industrial noise and deal with the sound absorption in building.
