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 tubes
*filtration 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, explosive etc
*soil adjusting agent, non-soil growing substrate, pesticide cleansing agent
