Product Details
Rock wool products is base on superior melted basalt as the main raw material, through centrifuge system of four-roller cotton process which pulls melted basaltic rockwool into a 4 ~ 7μm non continuous fibers followed by adding a certain amount of binder, dust laying oil, water repellent before settlement folding, curing, cutting and other processes, and then made into the products of different density depending on purpose of usage like blanket or board or pipe etc shapes,meanwhile it can be non-faced or faced with wire mesh. This material using in construction, Petroleum, electric power, chemical industry equipment’s thermal insulation and Building partition wall, curtain wall, roof and building envelope thermal insulation.
Features
- Excellent fiber strength, low shot content and excellent heat presentation.
- High hydrophobic fate, low moisture absorption rate.
- High porosity enables the rock wool products has good sound absorption.
- Fireproof and excellent thermal insulation.
Applications
- Power equipment
- Industrial furnace
- Oven, heat treatment equipmen
- Petrochemical equipment, oil tank
