Description

Perlite Beads Grade 5 is a high-purity, expanded aluminosilicate mineral processed into uniform spherical beads. This engineered form is critical for applications requiring consistent particle size, low dust, and excellent flow characteristics. It is essential for industries such as pharmaceuticals, advanced filtration, and high-performance insulation where material uniformity and reliability are paramount.

Application

• Pharmaceutical Filtration: Used as a filter aid and pre-coat material in the purification of antibiotics, enzymes, and other sensitive biological solutions.
• Catalyst Support: Serves as an inert, high-surface-area carrier for catalysts in petrochemical and fine chemical synthesis.
• High-Temperature Insulation: A key component in refractory castables and insulating bricks for furnaces and kilns.
• Cryogenic Insulation: Employed as a loose-fill insulating material for tanks and pipes storing liquefied natural gas (LNG) and other cryogens.
• Horticulture & Hydroponics: Provides an optimal sterile, inert, and aerating growth medium for soilless cultivation and root zone management.
• Construction Materials: Used as a lightweight aggregate in plasters, mortars, and concrete to improve insulation and reduce density.
• Industrial Absorbents: Effective for spill cleanup of oils and hazardous liquids in industrial settings.
• Polymer & Composite Filler: Imparts lightweight, insulating, and fire-retardant properties to plastics and composite materials.

Quality Control

Our Perlite Beads Grade 5 is manufactured under a stringent quality management system. Production is monitored against strict specifications for particle size distribution, bulk density, pH, and loss on ignition. While not a pharmacopoeial substance, production follows GMP principles where applicable. A comprehensive Certificate of Analysis (COA) detailing physical and chemical parameters is provided with each batch to ensure traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep containers sealed when not in use to prevent moisture absorption and contamination. Store away from strong acids and alkalis.
