The use of perlite offers many functional and long-term economics advantages to the construction industry. Among the major applications are as a aggregate in lightweight concrete and plasters, as a loose fill insulation product to fill cavities of masonry brick walls, as an ingredient in the manufacture of insulation boards, bricks and tiles.

The glassy closed cellular structure gives perlite a very low thermal conductivity, combined with the lightweight and low combustibility making it the ideal material for thermal insulation. Insulation of rooftops with perlite concrete to reduce heat gain into the building is a popular application.

The large irregular surface area of Perlite Particles make them a useful ingredient in sound absorbing material designed for acoustical treatment to prevent reflection and reverberation of sound from ceiling and upper wall areas. Perlite is also a principle ingredient in acoustical plasters and tiles manufacture.

Perlite displays a low thermal conductivity through a wide range of temperatures, pressure and densities. This attribute makes it the ideal insulation material for cryogenic products storage even as low as -268 deg.C. Its fine particle size combined with the inert nature and free flowing nature makes filling and removal an easy task.Apart from being used for insulation of big cryogenic tanks, like LNG, Oxygen, Ethylene and Nitrogen. It is also used to insulate air-separation plants, vacuum and non-vacuum small tanks and small tanks and small cold and hot storage containers like flasks.

The capacity of perlite to adsorb water, improve aeration and provide proper drainage makes it an excellent product for horticulture application. Since perlite is inorganic sterile, chemically inert with a neutral pH, the lightweight insulating properties which reduces extremely the soil temperature fluctuations makes perlite use as a unique growing medium and soil conditioner.The product find wide application in plant propagation, cultivation of crops, domestic gardening, stadium turf lawn conditioning, seed propagation, tissue culture hardening, nurseries, green house growing and landscaping.

Perlite functions as a filter aid to facilitate easy separation of the liquid from the solid particles in industrial filtration by improving flow rate of filtrate and also achieving the required clarity. Perlite does not interfere chemically with the slurry and impart no taste, colour or odour to the filtrate product and this quality has extended its use in the food and beverage industries. Other applications include, pharmaceuticals, chemicals, water, paints and resins, oils, sugar, beer, wine and industrial coatings.

Perlite is used as a lightweight, low iron content ingredient in insulating castables used in petrochemical, sponge iron and cement plants.It is also used in refractory bricks that find application of back up insulating layers in boilers, industrial furnaces etc.

Fine perlite aggregate with a blend of non-ionic surface-active agents can be used as a safe hand and industrial cleanser in work spots like project site where water is scarce. Grease and oils from soiled hands can easily be removed by rubbing the cleanser between the palms and wiping with a cry cloth.This application is very popular in Japan but it is still penetrate other markets around the globe.

Perlite is used in cement mixture for consolidation of the soil during oil well drilling to prevent losses of drilling fluids. Perlite cement is not affected by heat, bridges voids and prevents effective binding.

For grinding wheels, discs, rubs and other abrasives, perlite as a filler allows for cooler and safer abrasion because of its porosity, resistance to disintegration and lightweight.

The light weight of perlite its white colour, its resistance to micro-biological degradation and its ability to adsorb moisture without clumping makes it ideal carrier material for veterinary medicine which is added to the poultry feed.

Perlite with its lightweight porous structure allows adhesion of surface active ingredients including enzymes is mildly abrasive, slowly breakdown into smaller particles. Also these make it suitable for use in garment washing and stone washed jeans.
