rock wool/mineral wool insulation board 

The rock wool/mineral wool insulation board is made from basalt as main ingredient, made into inorganic fiber in high speed centrifugal machine after melting and a certain amount of cementing agent, rustproof oil, silicon oil is added into the raw material which is made into the rock wool board, rock wool pipe and rock wool blanket according to different requirement.

Features of rock wool/mineral wool insulation board:

1.energy conservation
2.excellent heat preservation and thermal insulation.
3.fire proof. it is made from natural rocks and it is non-combustible material.
4.physically and chemically stable, aging resistant and consistent thermal performance.
5.niose absorption.
6.easy handing and installation.
