Resistant to gas jet Low thermal capacity, light weight Various shapes depending on application
Vacuum formed shapes are hard-fiber products made of bulk using using wet vacuum suction filter into shape. These can made to 300-600kg/m3 different specifications, performance of the different blocks, panels, different standard precast, burner, the concept of cracking furnace fire hole, drums, etc. Chemical of V series filter vacuum suction pressure molding shapes was neutral. These dont restored by the majority of strong acid-base and atmosphere of erosion, except hydrofluoric acid, phosphoric acid and alkali. After the invasion of oil, water or water vapor and drying, these dont effect physical and heat resistance of pieces. Molten aluminum or zinc will not hurt the vacuum forming products, serialization varieties satisfie the complex requirements for thermal.
