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
