What are the product features of rock wool blanket?

Release Time: 2025-07-22

Rock Wool Blanket is mainly used for insulation and noise reduction of exterior walls and roofs of steel structure plants, also thermal insulation for industrial tanks etc. to improve fire performance and insulation.

Rock wool roll felt is produced using an internationally advanced four-roller centrifugal cotton processing procedure, incorporating a certain amount of binder and dust. It is primarily made from fine basalt, which is melted and processed into 4-7um non-continuous fibers. Through techniques such as sedimentation, solidification, and cutting, it can be made into a series of rock wool roll felt products with different densities according to different applications. Depending on the packaging purpose, it is divided into ordinary felt, glass cloth seam felt, aluminum foil felt, and steel wire mesh seam felt.
