Product Description

Expanded perlite is white color material with multi applications ,which is processed by perlite sand after  preheating then expansion at once in professional electricity furnace,its inside structure is in honeycomb shape.Its expansion rate is about 10-30 times..

Main excellent characteristics of expanded perlite:

1. excellent chemical stability,
2.  low coefficient of thermal conductivity,
3. low water absorption,
4. non-toxic, non-smelling,
5. excellent insulation properties,
6.  low bulk density

Application of expanded perlite:
 

Building Industry:	Produce light, thermal insulation and acoustic board; Be ideal materials of various industrial equipment and pipe insulating layer;
Fillter Aid and Filler	Be filtering agent,when making wine,drinking, syrup,vinegar etc; Purify various liquid and water,coming up to innoxious to human and animal;Be filler of plastic,rubber, , enamel etc;
Agriculture and Horticulture	Reform soil and adjust soil hardened;Prevent plants from falling down and control fertilizer efficiency and fertility;Be diluent  and carrier of biocide and herbicide.
Mechanism, Metallurgy, Hydropower and Light Industry	Be ingredients of heat insulation glass, mineral wool and porcelain products etc.
Other Aspect	Be packing materials of exquisite products and pollution products; Be abradant material of gem,colourful stone,glass products; Be density regulator of explosive, treating-agent of sewage.
