1 Products availableOur Complete range of products are Wedge-Microporous Insulation Board, Wedge-Refractory Insulation Millboards sheet, Wedge-Ladle Insulation Boards, Wedge-Vermiculite insulation board and Wedge High Temperature Resistant Millboards.
microporous insulation boards are manufactured by mixing high quality agglomerates of pyrogenic silica and selective grade opacifiers along with filaments and pressed at a very specific pressure range to achieve a very narrow range of optimum highest possible porosity and unique range of densities to deliver a product with lowest possible heat loss through conduction, convection, radiations, and gaseous conduction. The thermal conductivity of microporous insulation is lower than the still air at high temperatures.

wedge perlite insulation board, also known as waterproof perlite insulation board, is made of expanded perlite bulk material asaggregate, adding waterproofing agent and binder for preparation, screening, pressure forming, drying processes.
expanded perliteis a white, ultra-lightweight aggregate ranging from a very fine powder to an aggregate with a particle size up to 6mm in size. It isinorganic, inert, neutral in ph, biologically stable and has no asbestos content. It has excellent thermal insulation properties over anextremely wide temperature range from cryogenics at minus 273c (absolute zero) up to refractory applications at over 1000c.
italso has a highly adsorbent surface and a very low bulk density which makes it an ideal carrier or low cost filler for many compoundformulations.
perlite insulation products have the benefit of containing a rust inhibitor which is activated if the insulation comes into contact withmoisture. The inhibitor neutralises any chlorides present, thereby greatly reducing, if not totally eliminating, corrossion underinsulation (cui).
advantages
light weight with very low bulk density.
waterproof with extremely high hydrophobicity.
low thermal conductivity.
most suitable for cryogenic applications -190c.
high temperature insulation up to 650 c.
fireproof, rot proof, damp proof, sound proof.
construction safety is simple and easy, roof and wall.
environmentally friendly.
water repellent, non-flammable, loose-pour insulant improves the thermalperformance on masonry walls and floors.
corrossion under insulation (cui) resistant.
