Perlite
Expanded perlite, an kind of internal honeycomb-like structure white granular material made from perlite ore that after it is preheated and instantaneous expands under high-temperature calcination.
Feature: white granular (internal honeycomb structure), nontoxic, tasteless, noncombustible, non-corrosive, neutral pH value (pH value: 6.5-7.5), acid resistant and alkali resistant, light weight, high absorption and insulation capability.
Main Chemical Content:
SiO2 | 68-76 |
Al2O3 | 11-16 |
Na2O | 4-5 |
Applications Because expanded perlite is good heat insulation, light weight, nontoxic, porous, and abundant reserved and low price, hence it widely used in following fields: lightweight construction insulation board, partition board, acoustic board, fireproof board.
Insulation materials for industrial furnaces and tubesfiltration agent for beer, drinking, food and medicine
slag collecting material for steel melting and insulation filler for air separator
Filler or expanding agent for rubber, paint, plastic, explosives etcsoil adjusting agent, non-soil growing substrate, pesticide cleansing agent
