Product Introduction

Made from volcanic rocks such as natural basalt and diabase. Raw materials are melted at temperature above 1450℃, then turned into inorganic mineral fibers by high‑speed centrifugal spinning. With special binder and dust‑proof oil added, rock wool products are finished through cotton collection, pendulum layering, curing and cutting processes.

Class‑B fire‑retardant inorganic mineral insulation material. Hardly combustible with low toxic‑smoke emission under high‑temperature conditions. Features outstanding thermal insulation, sound absorption and fire‑resistance. Stable chemical property, excellent aging resistance, corrosion resistance, water‑repellent & moisture‑proof performance, anti‑mildew with long‑term stable physical‑chemical performance. Non‑toxic and eco‑friendly for civil and industrial buildings.

Product Structure

Main component: basalt mineral fibers, cured with organic binder and water‑repellent agent. Single‑side or double‑side lamination available with finishing layers including fiberglass cloth, aluminum foil and fiberglass felt. Processable into rock wool board, rock wool strip, rock wool blanket and rock wool pipe shell.

Main Performance

• Low thermal conductivity for high‑efficiency thermal insulation
• Porous fiber structure for excellent sound absorption
• High chemical stability, acid & alkali resistance, anti‑aging
• Water‑repellent, moisture‑proof and anti‑mildew
• Non‑toxic, environment‑friendly

Application Scenarios

External wall thermal insulation, fire‑stop insulation strips for curtain wall, roof fire‑proof & thermal insulation, interior partition sound insulation, fire‑protection cladding for steel structures; Thermal insulation for industrial boilers, heating pipelines and storage tanks; Fire‑proof and sound‑absorbing projects for subways, machine rooms and public buildings.
