Adsorbent Perlite Technical Data Sheet

Introduction

Expanded perlite is an ideal medium used to control and clean up liquid spills, it may also be used to provide radid deodorization and dehydration of animal waste liquids and as an adsobent media in enclosed containers for the disposal of liquid toxic waste substances. Perlite is recommended as a carrier for pesticides, herbicides, feed concentrates and other similar applicaitons. it will readily adsorb concentrates while remaining free flowing (anti-caking) and chemically resistatn to microbiological degradation.

Source

Perlite is a generic term for a naturally occurring siliceous volcanic rock. This is quarried, crushed and screened into closely graded fractions having a specific range of particle size to suit various applications.

Manufacture

The expansion of Perlite is produced by the raw grade ore being fed through a furnace at an elevated temperature. The melting particles cause the water in the structure to rapidly turn to steam thereby creating countless tiny air bubbles within the heat – softened glassy granules. It is these tiny glassy sealed bubbles which create the cellular structure of the ultra lightweight of expanded perlite.

Applications

The adsorption and removal of:

Chemical spills
Oil and water spillages from floors
Nuclear waste
Hazardous chemicals
Molten materials

A carrier of anti-caking agent for:

Liquid fertilisers
Pesticides
Herbicides
Feed concentrates
Vegetable and fish oils

Benefits

It is the multicellular nature and high surface area of expanded perlite which accounts for the excellent adsorption properties. This plus the ability of the product to create a low slip surface gives it an advantage over any other products available.

Performance

Water adsorption capacity of expended Perlite is as follows:

Grades	P05 Ultrafine	P10 Superfine	P321 Throughgrade	P45 Supercoarse
Particle Size	0.01 - 0.75 mm	0.15 - 2.0 mm	0.15 - 6.0 mm	1.0 - 6.0 mm
Water Uptake (kg/m³)	880 - 900	630 - 650	470 - 490	380 - 400
