BTU-BLOCK Microporous Insulation Finds Many Uses
Thermal Ceramics (Augusta, GA, USA) says that its high performance BTU-BLOCK microporous-based insulating products, claimed to be the most efficient high temperature systems currently available, are now finding wide acceptance in industrial applications.
One major advantage of the product, says Thermal Ceramics, is its greatly reduced thermal conductivity for a given thickness compared with conventional insulation products. For example, at 538°C, microporous insulation has a thermal conductivity one-third that of a ceramic fibre blanket and one-quarter that of 1260°C class insulating firebrick. This means that 25mm thick BTU-BLOCK will give approximately the same heat transfer results at 538°C as 75mm thick ceramic fibre blanket or 100mm thickness of equivalent class insulating firebrick.
A further advantage is the performance under compression. The compression of BTU-BLOCK insulation actually improves its uniformity and thermal performance as it slightly deforms and, unlike typical rigid insulation system, microporous insulation products do not reach a critical load/deformation point. BTU-BLOCK also exhibits very low shrinkage in use as back-up insulation at temperatures up to 982°C and is easily installed in most applications - typically, fibre cements or sodium silicate are used to keep it in place.
