Perlite is a naturally occurring siliceous rock of volcanic origin. This rock when crushed and heated under proper conditions expands to 20 times or more of its original volume. A special milling and classification process gives the correct particle size distributions needed for optimum performance as a filter aid. Perlite FILTER AID improve filtering efficiency by increasing the permeability of the filter cake and is either added to the suspension to be filtered or built on the filter media as a layer through which the liquid must pass. The physical character of expanded perlite bubbles lends itself to a variety of special purposes – including use as a filter aid separating small solid particles from liquids. Lightweight expanded perlite bubble structures are milled and classified using clearly defined processes to produce perlite FILTER AID with specific flow characteristics. The various grades utilize the jagged interlocking structures (see image right) to create billions of microscopic channels between the filter aid particles to produce optimum flow rates and clarification abilities for a wide variety of applications.

perlite concrete block and is preferred worldwide for the bottom ring beams of double walled cryogenic tanks to provide excellent thermal insulation and structural support to static and dynamic loads.Kelite perlite concrete blocks combine high compressive strength with a low thermal conductivity to meet critical requirements in terms of strength and thermal insulation. Kelite blocks are of standard grade or can be made as per customer requirements with respect to compressive strength and thermal conductivity by changing the mix-ratios.

The ore used to manufacture Radiolite® FILTER AID is a formation consisting of the fossilized remains of diatoms, a form of plankton that lives in lakes and oceans. These unicellular form of life develop cell walls, or frustules, from silica ingested in the process of absorbing nutrients from surrounding water. Accumulations of fossilized diatoms frustules form deposits of diatomite, the raw material from which Radiolite® products are processed. Keltech Energies Limited has been appointed by Showa Chemical Industry Company Limited, Japan as the sole distributer for Radiolite® - Diatomite Filter Aid for the Indian market and neighbouring countries like Sri Lanka, Bangladesh, Nepal & Bhutan.
