What is phenolic foam made of?
Phenolic foam is made from three main components: phenolic resin, a blowing agent and an acid catalyst; a number of additives can also be utilised to develop specific properties within the foam.
Is phenolic foam flammable?
But there is another popular type of combustible plastic foam, known as “phenolic” foam, which is held to have quite different fire performance.
Is phenolic foam sustainable?
Phenolic foam has a reasonably high embodied carbon if compared to other materials, however due to its recognised savings in this category in-use it is not of prime concern. Other categories with high impacts include freshwater ecotoxicity and water resource depletion.
Is phenolic foam combustible?
Is phenolic foam a polymer?
Phenolic resins are synthetic polymers produced by polycondensation between phenol and formaldehyde.
Is phenolic insulation better than PIR?
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.
Is phenolic fire resistant?
“Being intrinsically fire-resistant, phenolic resins offer a better safety margin without the need for flame- retardant additives or gel coats,” says Pisipati. “This allows them to be used for even fine weave cloths for thin parts.
What is the fire rating of phenolic insulation?
2 hours fire
In addition, phenolic foam used in factory engineered composite panels can achieve up to 2 hours fire resistance rating (insulation/integrity) in the 3m furnace test.
Is phenolic non-combustible?
Is phenolic foam harmful?
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.
Is phenolic foam fire resistant?
Phenolic foam can, in an appropriate form, achieve all the following European fire certifications. In addition, phenolic foam used in factory engineered composite panels can achieve up to 2 hours fire resistance rating (insulation/integrity) in the 3m furnace test.
Is polyethylene a foam?
Polyethylene is a closed cell foam, also referred to as a PE foam or LDPE foam. The material starts off as a thermoplastic which is then blown into a foam format. This is a highly durable as well as versatile product.
