 Products 



 Obturator perlite (also known as enamelled perlite, lightweight hard shell perlite) is a new perlite. The product is evenly from the inside out by a certain particle size small perlite material reaches a certain temperature in the vertical electric furnace cascade heating mode expansion, expansion of the particle surface but also by the instantaneous high temperature vitrified by cooling to form a continuous glass qualitative particle surface, and maintained within the porous, hollow hollow structure, the unique mode of production products to maintain the purity of the natural inorganic chemical composition of perlite. Obturator perlite to overcome the traditional expanded perlite water absorption of large, low intensity, poor mobility, extension of expanded perlite applications, with high strength, light weight, insulation, electrical insulation properties, high purity, uniform particles, low water absorption, good fluidity and other notable features. 



 Features 



 Intuitive was a micro-round granular, reflective continuous glassy smooth outer surface of the capillary sorption and compressive strength, clay, cement and other materials in the wet slurry state combined with a high degree of mobility. 



 Product Use 



 Can replace the sand for aggregate preparation of interior and exterior insulation mortar, making the decorative sheet of high-grade insulation, composite insulation coating ingredient, filter materials, refractory bricks, the main ingredients of the enamel materials, construction, metallurgy, industrial kilns and electric insulation, heat pipes and other high-grade insulation materials and lightweight filler.
