Perlite has outstanding insulating characteristics, and is lightweight. In addition to providing thermal   insulation,   Perlite   enhances   fire ratings, reduces noise transmission and it is rot, vermin and termite resistant. Perlite is also ideal for insulating low temperature cryogenic vessels. When Perlite is used as an aggregate in concrete, a lightweight, fire resistant, insulating concrete is  produced that is ideal for roof decks and other applications.

Perlite  can  also  be  used  as an aggregate in Portland cement and gypsum plasters  for  exterior  applications  and for fire protection of beams and columns.  Other  construction  applications include under floor insulation, paint  texturing, gypsum boards, ceiling tiles, roof insulation boards and mortars.

The processing aids division has a highly efficient portable perlite plant which is used to produce expanded loose-fill perlite on customers’ sites at any location world-wide. Our staff have many years’ experience in the operation of this portable perlite plant, including vast experience in the pneumatic conveying of expanded perlite.

Strict health, safety and environmental procedures are followed and the plant is operated in accordance with ISO 9000 quality management standards. This expansion process creates countless cells in the glassy particles, which account for the excellent thermal insulation properties of expanded perlite. The superior insulation characteristics, especially at low temperatures, as well as the fact that perlite is stable and inert, makes it the ideal material for use in cryogenic insulation applications.

The processing aids division has insulated more than fifty (50) cryogenic units by means of the portable plant on-site method. These include air separation units, heat exchangers, liquid nitrogen, oxygen, natural gas storage vessels, pipe ducting and marine tanker ships. We have successfully completed contracts where perlite insulation volumes in excess of 5000 cubic meters have been required and where the product was pumped up to heights of 70 meters.

The prestigious project engineering companies we have worked with include Air Liquid, Air Products, BOC, BSL Industries, MEI, Messer Fedgas, Spie Batignolles and L&C Steinmuller.
