Perlite Board




Wedge Perlite board, also known as waterproof perlite insulation board, is made of expanded perlite bulk material as aggregate, adding waterproofing agent and binder for preparation, screening, pressure forming, drying processes. Expanded perlite is a white, ultra-lightweight aggregate ranging from a very fine powder to an aggregate with a particle size up to 6mm in size. It is inorganic, inert, neutral in pH, biologically stable and has no asbestos content. It has excellent thermal insulation properties over an extremely wide temperature range from cryogenics at minus 273°C (absolute zero) up to refractory applications at over 1000°C. It also has a highly adsorbent surface and a very low bulk density which makes it an ideal carrier or low cost filler for many compound formulations.

Perlite Insulation products have the benefit of containing a rust inhibitor which is activated if the insulation comes into contact with moisture. The inhibitor neutralises any chlorides present, thereby greatly reducing, if not totally eliminating, corrosion under insulation (CUI).

• Light weight with very low bulk density.
• Waterproof with extremely high hydrophobicity.
• Low thermal conductivity.
• Most suitable for cryogenic applications -190°C.
• High temperature insulation up to 650 °C.
• Fireproof, rot proof, damp proof, sound proof.
• Construction safety is simple and easy, roof and wall.
• Environmentally friendly.
• Water repellent, non-flammable, loose-pour insulant improves the thermal performance on masonry walls and floors.
• Corrosion under insulation (CUI) resistant.

• High temperature insulation and heat protection
• Cryogenic application: Non-combustible ultra-lightweight mineral aggregate with excellent insulation & adsorption properties.
• Fire proofing and sound proofing.
• Swimming pools, cold storage, boilers and some insulation projects with special requirements for waterproofing.
• Perlite insulation is used in high temperature applications in the steel and foundry industries such as ladle topping, hot topping and riser.
• Expanded Perlite is suitable for a range of landscaping applications such as green roof construction, golf green renovation and construction, planters, drainage.
• Expanded perlite powder and board is a hydrophobic insulating aggregate.
