Perlite(gradening grade)
The material comes from volcanic lava.It is a kind of amorphous,glassiness volcano that contains cystalline water inside.For expanded perlite has low density and low heat conductivity characters,it is widely used in construction and manufacturing fields,lightweight plasters and mortars,insulation,ceiling tiles and filter aids.In horticulture,it makes composts more open to air,while having good water-retention capacity.It is good carrier for soilless plant.Since last few years,expanded perlite is more and more popular in cryogenic use.
Horticultural Applications
In horticultural applications,perlite is used throughout the world as a componet of soilless growing mixed where it provides aeration and optimum moisture retention for superior plant growth.Other horticultural applications for perlite are as a carrier for fertilizer,herbicudes and pesticides and for peletizing seed.
Features
Through being expanded,perlite is light,multi-fnctional,new materials. |
It has light apparent density,low thermal conductivity,fine chemical stability and wide use temperature range. |
It is non-toxic,flavorless,fireproof,acoustic etc. |
It is widely used in many industries. |
