Phenolic insulation is a rigid, closed-cell foam product that offers very good performance due to low thermal conductivity. Phenolic foam insulation is typically manufactured in large buns that are then fabricated into pipe cover, curved segments, tank heads and sheets.
Is phenolic a good heat insulator?
Phenolic foam is considered one of the best material for thermal insulation. ... The thermal conductivity of phenolic closed cell insulation material is generally between 0.018 W/m.K and 0.023 W/m.K. It has fire retardant properties and a low smoke level (even under pyrolysis).Oct 2, 2020
Does phenolic insulation burn?
When exposed to heat, phenolic insulation undergoes a process called pyrolysis (thermal decomposition). This results in two products: hot combustible gases (pyrolysis gasses) and a black char which forms on the surface of the material.May 29, 2019
How is phenolic insulation made?
Phenolic insulation is manufactured by a process in which a plastic foam forms an insulating core between two flexible tissue faced layers. It has a high closed cell content and fine cell structure. Rigid phenolic insulation is produced by mixing high solids and phenolic resin with a surface acting agent.
What is the most efficient pipe insulation?
Phenolic foam insulation
What is phenolic insulation used for?
Phenolic Resins Foam Phenolic foam is a versatile material used in a wide variety of applications where thermal performance, moisture resistance, fire performance and even structural strength are key performance criteria.
What is the difference between PIR and phenolic insulation?
As with the PIR/PUR boards above, phenolic insulation boards also have a closed cell structure. Phenolic board has a slightly higher r-value (higher is better, unlike u-values) and a slightly thinner profile than PIR/PUR boards due to the manufacturing process.
