After successfully manufacturing and marketing Ceramic Fiber Products, high "ShreeCera" temperature insulation material, have now entered into production arena of a "ShreeFoam" low temperature industrial insulation material making available insulation material required for high temperature and low temperature insulation under one roof.
Polyurethane (PUF) foam has outstanding insulation properties to maintain temperature in 0cold / hot environments. PUF Materials are suitable for temperature range between -180 C to +110°C.
Polyisocyanurate (PIR) foam slabs and pipe sections are suitable for use between -200°C to +150°C. It has low thermal conductivity value of maximum 0.021 w/mk at 10°C. It is not easily ignitable and has negligible water permeability and is most suited insulation material for cold/chilled pipelines & equipments. PIR is the recommended insulation material for LNG pipe insulation.
“ShreeFoam” Rigid PU foam cored pipe sections manufactured and are available in varied sizes and density. Being CFC free polyurethane Foam, it is "Environment Friendly" and have excellent dimensional and thermal insulation properties together with compressive strength
“ShreeFoam” PIR has low smoke emission and will not melt or dip in a fire. PIR being Polyisocyanurate foam, has a higher hot surface performance upto 150°C compared to 110°C of normal Polyurethane foam.
