Phenolic material is made of phenolic foam material and belongs to polymer organic hard aluminum foil foam products. It is foamed by thermosetting phenolic resin. Phenolic material has the properties of light weight, fireproof, non-burning in case of open flame, smokeless, non-toxic, and non-drip, and has a wide range of operating temperatures. This material is known as the "king of insulation materials" and is a safe, green, new energy-saving building material. Its advantages have been recognized by construction departments and public security fire departments. Phenolic materials are widely used. They were used for the insulation of missiles and rocket heads in the early days, and are now widely used in high-rise buildings, transportation, ships, aviation, space technology and other fields. In addition, pipe shell products cut from phenolic insulation boards are also widely used in pipeline insulation fields such as petrochemicals. Composite products of phenolic insulation boards are used in large-scale built-in systems in building insulation projects, a-class fireproof insulation systems, building wall insulation and decoration integrated systems, fireproof door interlayers, color steel sandwich houses, etc. 1.
Phenolic materials also have excellent physical and chemical properties, such as low density, high width, adjustability within a certain thickness range, vertical bending strength, low water absorption, and excellent thermal insulation performance. These characteristics make phenolic materials have important applications in many industries.
