Muscotherm® MS500 & p700 are mica based products suitable for continuous operating temperatures up to 700°C. Manufactured from muscovite or phlogopite mica paper together with silicone resins the materials are resistant to high temperature. Muscotherm MS500 & P700 exhibit high flexural and compressive strengths together with very low thermal conductivity. The products are ideally suited for environments where hard wearing materials are required.

Muscotherm flx is a mica based product similar to the MS500 & P700 rigid grades, however the mica is impregnated with a resin, which remains flexible after polymerisation. The material remains sufficiently pliable to take the shape of the part being insulated. Muscotherm flx is suitable for continuous operating temperatures up to 500°C.

Muscotherm  fbr is flexible mica paper bonded to 1260 grade ceramic fibre paper. The product exhibits exceptionally low thermal conductivity whilst operating at high temperatures. The product is ideally suited to applications where temperatures need to be greatly reduced but thickness of insulation is restricted.
