Polyurethane Hard Foamed Plastic Rockwool Tube

Resin rockwool and waterproof rockwool is made mainly from deliberately selected slag of diabase and basalt by means of adding special bonding and waterproof bonding in the course of high speed centrifugation after melt under high temperature.
On the basis of absorption and master of advanced technique and devices at home and abroad and according to China’s national conditions and characteristics of raw materials, the large resin wool production line developed by company along with experts in rockwool industry has smartly combined with plate and tube production lines, which is more perfect and fill the blank that other production lines can not make large tube shell, large profiled tube shell and large profiled rockwool plate. The products are welcomed by many customers because of its promoted product quality and varying specifications and varieties.
With extensive purposes, rockwool products are applicable in industries such as building, petroleum, power, metallurgy, textile, national defence, traffic and transportation. They are ideal materials for thermal insulation and sound insulation of industrial equipments such as pipeline, storage tank, boiler, flue, heat exchanger, fan , vehicle and ships.
