Polybond Rockwool Superfine Loose Mineral & Granulated Wool

          Polybond Rockwool Superfine Loose Mineral Wool is a collection of fine fibers drawn from molten selected basalt rocks. The Mineral Wool is an ideal material for most insulation applications because of its favourable handling and application characteristics. It is fire proof, dirt proof and moisture resistant. Chemically, it neither reacts nor accelerates corrosion. It is durable, odourless, easy to handle and store and conforms to IS:3677.

          The Loose Mineral Wool and Granulated Wool possess low thermal conductivity on account of enormous minute air cells created by the fine fibre and can be used in a wide range of temperatures of -50°C to 750°C. It is oil free and has prudent low thermal conductivity properties.
