Rockwool board tubes and felts, glass wool board tubes and felts, wholesale of Jinhua silica-alumina board tubes and felts. Rockwool board is madeBasaltInorganic fiberboard produced by high-temperature melting and processing of main raw materials; also known as rock wool board.Insulating Decorative PanelsRock wool board is a man-made inorganic fiber produced through high-temperature melting, characterized by its light weight, low thermal conductivity, heat absorption, and non-flammability. Initially developed, it is commonly used in the construction industry, and its application types should comply with the "Application Types and Basic Requirements of Building Insulation Materials." In June 1981, the rock wool board was successfully tested as a new type of insulation, fire-retardant, and sound-absorbing material.

Alumina silicate fiber, also known as ceramic fiber, is a new type of lightweight refractory material. It boasts advantages such as low bulk density, high resistance to high temperatures, good thermal stability, low thermal conductivity, small heat capacity, excellent resistance to mechanical vibration, minimal thermal expansion, and superior insulation properties. Through special processing, it can be made into products like alumina silicate fiber boards, felts, ropes, and blankets. The new sealing material features high resistance to high temperatures, low thermal conductivity, light bulk density, long service life, high tensile strength, and good elasticity. It is a novel material replacing traditional ones and is widely used for insulation on thermal equipment in metallurgy, power, machinery, and chemical industries.
