Expanded perlite 
 Expanded perlite is a non-toxic, tasteless, non-combustible, does not rot, acid, heat, noise insulation, internal honeycomb structure product by crushing and screening to acidic volcanic glassy lava (Perlite) must particle size, and then preheated delay sintering at temperatures above 14000 ℃ and made a white or light-colored high-quality insulation materials, such as hydrophobic perlite products prepared with different binder made, perlite sound-absorbing panels, wall board, fireproof board. 
 The expanded perlite is acidic volcanic glassy lava (Perlite) by crushing, screening, to a certain size, then the warm-up, instant high-temperature calcination and made a white or light-colored high-quality insulation materials. The particles within the honeycomb structure, non-toxic, odorless, does not rot, non-combustible, acid and alkali. Different performance of the products and can be made with a different adhesive, which is characterized by light weight, good thermal insulation and sound-absorbing performance and abundant raw materials, low prices, use of safe, convenient construction, can be widely used in petroleum, chemical, power, construction , and metallurgical industries. Used in agriculture, gardens on fertilizer, water, sterile, good air permeability. 
 Application: Expanded perlite is a wide range of applications of a material, involving almost all fields, For example: (1) oxygen plant, cold storage and transportation of liquid oxygen liquid nitrogen fill insulation. ② used for products such as alcohol, oils, medicines, food, sewage filter. (3) used in rubber, paints, coatings, plastics, and other fill materials and vasodilators. ⑤ used to adsorb the oil slick. ⑥ for agriculture, horticulture, soil improvement, water and fertilizer. ⑦ used in conjunction with various adhesives made from a variety of specifications and performance profiles. ⑧ a lot more for the industrial furnace and the building roof and wall insulation. 
 The application of a variety of expanded perlite of manufactured goods in addition to the expanded perlite Therefore, some thermal insulation properties, as a basic, mixed with the binder, the products can adapt to different needs.
