Best Quality Perlite in China!
Expanded Perlite
Product Description
Expanded perlite is a natural acidity glass lava nonmetallic minerals,including perlite,rosin rock and obsidian,only three different crystallization water content.in 1000-1300 ℃ high temperature under the condition of it's rapid expansion volume 4-30times,therefore,collectively known as expanded perlite. General requirements expansion ratio >7-10 times (black obsidian >3 times,available), silicon dioxide by about 70%. Don't need separation,crushing,screening.
Applied Area
Can be used as a filtering agent,catalyst,molecular sieve and rubber,the carrier offertilizers and pesticids. Widely used in construction,metallurgy,petroleum,macbinery,light industry,water and electricith,casting,medicine,food,agriculture,forestry and gardening departments and so on.Often temperature coefficient of thermal conductivity of 0.0245-0.048w/ (m K), high temperature heat conduction coefficient is 0.058-0.175W/ (m K), low heat conduction coeffient is 0.028-0.038 W / (m K),the highest temperature is 800℃. Used as efficient insulation,cold insulation filling material.
