Phenolharzschaum

Phenolharzschaum, also known as phenolic foam, is a rigid closed-cell foam insulation material derived from phenol-formaldehyde resin. It is manufactured through a foaming process where a blowing agent is introduced into the liquid resin mixture, causing it to expand and solidify into a cellular structure. This process results in a material with a high proportion of closed cells, which are crucial for its insulating properties.

The key characteristics of phenolharzschaum include its excellent thermal insulation performance, with a low thermal conductivity that remains stable over time. It also exhibits good fire resistance properties; it is inherently flame retardant and does not melt or drip when exposed to fire, instead charring and forming a protective layer. This makes it a suitable choice for applications where fire safety is a concern.

Phenolharzschaum is lightweight yet possesses good compressive strength, allowing it to be used in structural applications as well as insulation. It is resistant to moisture ingress due to its closed-cell structure, which contributes to its durability and long-term performance in humid environments.

Common applications for phenolharzschaum include building insulation, such as in walls, roofs, and floors, as well as in heating and cooling pipes. It is also used in the construction of refrigerated transport vehicles and in the aerospace industry for its lightweight and fire-resistant qualities. The manufacturing process allows for various forms, including boards, sheets, and sprayable formulations.
