Fire Retardant Thermal Insulation PF Phenolic Panel

Thickness of aluminum foil:
  • Air conditioning duct plate

  • WT



Phenolic insulation board actually consists of two flexible facing layers joint by plastic foam which presents the insulating core. The manufacturing process is based on the use of mixture of phenolic resin and high solids with a surface acting agent. Due to the heat that this reaction creates, bubbles in the material occur, produced by a liquid blowing agent, such as pentane, which is commonly used. In order of eliminating the risk of blowing agent being replaced by air over time, boards are often faced with glass tissue or  aluminum foil. The final result could be either sheet material cut into boards or blocks cut into previously determined shapes.
