bulk Closed Cell Perlite For Thermal Insulation Mortar
closed cell perlite is made of perlite ore with a certain particle size in a vertical electric furnace cascade heating method, and then expands uniformly from the inside to the outside after reaching a certain temperature. The surface of the expanded particles is vitrified at an instant high temperature, and the continuous vitrification is formed after cooling. The surface of the particles, and the inside maintains a complete porous, hollow structure. The unique production method determines that the product maintains the purity of the natural inorganic chemical composition of perlite. The structural feature of the product is that the surface of the particles is micro-pores and continuous vitrified luster, and the content shows a few or dozens of tiny spherical accumulations, and the color is white. The bulk density of the product is 110～350kg/cubic; the particle size is 5～1500μm.

high temperature expanded perlite for sale
Expanded perlite is a kind of white granular material with honeycomb structure inside, which is made by preheating perlite ore and then roasting and expanding at instantaneous high temperature. The working principle of Expanded perlite is: perlite ore is crushed to form ore sand of a certain size, after preheating roasting, rapid heating (above 1000 ℃), the water in the ore evaporates and expands inside the softened vitreous ore to form a porous structure and volume expansion 10-30 times the non-metallic mineral products. Perlite is divided into three forms according to its expansion technology and use: open cell, closed cell, and balloon.

best pure Hydrophobic Perlite Used in External Insulation
Hydrophobic perlite is hydrophobically modified on the basis of expanded perlite to achieve excellent waterproof effect. Its thermal conductivity is low, generally around 0.045W/m.k, and the lowest is 0.041W/m.k. The outer surface has a sealed glass bulb, so thatHydrophobic perlite has high compressive strength and is not easy to be destroyed, which can greatly reduce the damage rate during use and effectively maintain the practical insulation effect. At the same time, the water absorption of the material is reduced, and the amount of water added to the proportion is reduced, so that the overall drying time of the material is significantly shortened, which helps to improve the construction efficiency.
