Expanded Perlite Powder / Nanopowder (Purity: >99%, APS: 80-100nm)

Expanded Perlite Powder / Nanopowder

What is Expanded Perlite Powder?

Expanded perlite powder / nanopowder is derived from perlite, a naturally occurring volcanic glass that expands when heated to high temperatures. The expansion process involves the perlite’s water content turning into steam, causing the material to puff up and create a lightweight, porous structure. When ground into a fine powder, it becomes expanded perlite powder or nanopowder, which has unique properties that make it useful in various industries.

Applications

Construction and Insulation Expanded perlite powder is widely used in the construction industry as an insulating material. Its low thermal conductivity makes it an excellent choice for insulation in roofing, walls, and floors. It is often mixed with cement to create lightweight concrete and is also used in plasters for heat insulation in buildings and industrial facilities.

Filtration Due to its high absorbency and porous structure, expanded perlite powder is used in filtration applications. It serves as a filter aid in various industries, including food and beverage processing, water treatment, and oil filtration. It helps remove impurities and improve the quality of the filtered material.

Agriculture and Horticulture Expanded perlite powder is commonly used as a soil amendment in agriculture and horticulture. When mixed with soil, it improves aeration and drainage, creating an optimal environment for root growth. It is also used in hydroponics, where the lightweight, sterile nature of perlite enhances plant growth.

Fireproofing and Passive Fire Protection Due to its high heat resistance, expanded perlite powder is used in passive fire protection materials. It can be found in fire-resistant coatings, fireproof panels, and as a component in fire retardant construction materials. The powder helps prevent the spread of flames and minimizes the damage from fires.

Nanotechnology and Nanopowder Applications When processed into nanopowder form, expanded perlite has potential applications in nanotechnology. The fine particles of expanded perlite nanopowder exhibit unique properties such as high surface area, which enhances their reactivity in certain applications. These nanoparticles can be used in:

Catalysts: Due to their high surface area, they can act as efficient catalysts in chemical reactions.

Drug Delivery: In the pharmaceutical industry, expanded perlite nanoparticles may be used in the development of drug delivery systems, helping to improve the efficacy and control of treatments.

Environmental Remediation: The absorbent nature of expanded perlite nanopowder makes it useful in cleaning up oil spills and other contaminants from water or soil.

Cosmetics and Personal Care Expanded perlite powder is used in cosmetics as a thickening agent or to improve the texture of various personal care products. Its fine, smooth texture helps to enhance the feel of lotions, creams, and powders. Additionally, it can be found in exfoliating products due to its gentle abrasive qualities.
