High-expansion foams have an expansion ratio over 200–1000 and are suitable for enclosed spaces such as hangars, where quick filling is needed. Alcohol-resistant foams contain a polymer that forms a protective layer between the burning surface and the foam, preventing foam breakdown by alcohols in the burning fuel.
These intumescent materials produce a light char which is a poor conductor of heat, thus retarding heat transfer.Typically the light char consists of microporous carbonaceous foam formed by a chemical reaction of three main components: ammonium polyphosphate, pentaerythritol, and melamine. [2]
Kaowool is a type of high-temperature mineral wool made from the mineral kaolin. It was one of the first types of high-temperature mineral wool invented and has been used into the 21st century. [4] It can withstand temperatures close to 1,650 °C (3,000 °F). [8]
UN numbers from UN3301 to UN3400 as assigned by the United Nations Committee of Experts on the Transport of Dangerous Goods are as follows: UN 3301 to UN 3400

Spray foam insulation extruding from a duct. Spray foam (expanding foam in the UK) is a chemical product created by a chemical reaction of two component parts, commonly referred to as side A and side B. [1] Side A contains very reactive chemicals known as isocyanate.
Instead the formula that would fit some of the Bonales data is k ≈ 2.0526 - 0.0176TC and not k = -0.0176 + 2.0526T as they say on page S615 and also the values they posted for Alexiades and Solomon do not fit the other formula that they posted on table 1 on page S611 and the formula that would fit over there is k = 2.18 - 0.01365TC and not k ...
Sealant is a substance used to block the passage of fluids through openings in materials, [1] a type of mechanical seal. In building construction sealant is sometimes synonymous with caulk (especially if acrylic latex or polyurethane based) [2] and also serve the purposes of blocking dust, sound and heat transmission. Sealants may be weak or ...
