WebThis indispensable guide will equip the reader with a thorough understanding of the field of foaming chemistry. Assuming only basic theoretical background knowledge, … Webfoam. Foams with a closed cell content of >90% are referred to as closed cell foam. Foams with a closed cell content of <10% are referred to as open cell foams. OPEN CELL Although the types of chemicals used to make open cell and closed cell foam are the same, the specific chemicals used differ. The blowing agent for open cell spray foam is water.
