Expanded perlite

  Fine grade expanded perlite consists of smaller, more uniform particles. It is typically used in applications where a smoother finish or tighter packing is required, such as construction materials and insulation. Its finer size allows it to fill voids more effectively and provide consistent performance. 

 Medium grade expanded perlite is a versatile, all-purpose material with a balanced particle size. It offers a combination of strength, insulation, and workability, making it suitable for a wide range of applications across construction, insulation, and general use.  

 Coarse grade expanded perlite consists of larger particles designed for applications where higher airflow, drainage, or lightweight bulk is required. It is commonly used where lower density and increased void space are beneficial, helping to reduce weight and improve overall performance.
