What is a phenolic insulation?
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.
Where is phenolic insulation used?
Phenolic foam is used in process/petrochemical applications for the insulation of pipework, tanks, vessels etc. Phenolic foam is also used in a number of highly specialised applications including fire doors, highly fire resistant panels and for insulation in surface ships, off-shore installations and submarines.
Does phenolic insulation absorb water?
Low water absorption is a key feature of Gulf Cool Therm Phenolic Foam A high closed cell content of up to 95% results in very low water vapour transmission and reduces condensation.
Is phenolic foam toxic?
The composition of the product in normal use does not present a significant health hazard. The reacted foam core has no known toxic effects. Dust generated is nuisance valve only but may cause irritation of the eyes, nose and throat.
What is phenolic insulation made of?
Phenolic foam insulation is made by combining phenol-formaldehyde resin with a foaming agent. When hardener is added to the mix and rapidly stirred, the exothermic reaction of the resin, together with the action of the foaming agent, causes foaming of the resin.
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.
Is phenolic insulation better than PIR?
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.
Is phenolic non combustible?
The first indicative test looked at the behaviour of Kingspan Kooltherm K15 Rainscreen Board, a phenolic, fibre-free rigid thermoset material, recognised as “combustible”.
How do phenolics work?
Phenols inactivate microbes through numerous means, such as cell lysis and by way of inactivation of their enzymes. Enzymes are protein molecules that are responsible for producing and accelerating chemical changes in a cell or body.
What is a phenolic resin foaming material?
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 can phenolic plastic be used for?
Asbestos
Is phenolic resin flammable?
Phenolic resins are generally less expensive than epoxies and polyimides, have a good temperature resistance, and are less flammable. Their biggest disadvantage is their low toughness, which limits their applications to those requiring high heat and combustion resistance. Phenolic Resins in Advanced Fiber-Reinforced Polymer (FRP) Composites
What kind of glue for phenolic plastic?
Epoxy. The strongest type of glue for metal to plastic is epoxy. Epoxy is a two-part liquid adhesive that cures when mixed.
