NR-60 or NR-85 materials are large-size, rigid insulating boards based on calcium silicate with a low thermal conductivity. They are specifically designed non-asbestos and reinforced with special selected fibers, which make it have a high mechanical strength and low shrinkage, it is an ideal material to offer stable and effective industrial insulation solutions.
NR-60 board is a rigid machinable insulation used as a thermal break in process plants and as skin insulation parts in apparatus, ovens and dryers, it works as a resized parts or a spacer in the industrial equipment and can be machined into special
NR-85 boards are strong dense calcium silicate boards ideally suited for applications where good insulation values and high mechanical resistance are required, they are employed not only in the general machine and apparatus construction sector but also as structural components for preventive fire protection, such as for pipe supports.
