Closed-cell perlite has high strength, low water absorption, and is easy to disperse, widely used in many fields such as thermal insulation mortar for walls, decorative panels, and as lightweight aggregate. It is also extensively applied in construction and metallurgy.

For this closed-cell perlite, there are many issues to be aware of during use. Below are several points summarized.

(1) Mechanically mixed to ensure uniform slurry; strictly control the water-cement ratio and plastering time to guarantee construction quality.

(2) Products should be stored with moisture and water resistance in mind, and the storage period should not exceed three months.

(3) This product does not require any additives for on-site construction. The mixed mortar must be used immediately, and any unused material slurry should not be watered down for reuse. Re-watering the material will lead to cracking of the plaster layer.

Its superior performance allows it to replace river sand as aggregate for the preparation of thermal insulation mortar for interior and exterior walls, as well as for the production of thermal insulation decorative boards, main material for composite thermal insulation coatings, filter aid raw material, refractory bricks, main ingredient for enamel materials, thermal insulation materials for construction, metallurgy, industrial kilns, electrical heat insulation, and thermal pipeline, as well as lightweight fillers.

Closed-cell perlite characteristics:

Visually round granules with a glossy, reflective glassy surface, exhibiting distinct capillary adsorption and compressive strength. High degree of bonding with materials like clay and cement in a wet slurry state, indicating good fluidity.
