Description

An additive that decomposes to form a gas. Some foaming agents, such dinitroso compounds (dinitroso pentamethylene tetramine) and hydrazides (benzene sulfonyl hydrazide) generate nitrogen upon heating. They are used in fire extinguishers and to produce foamed plastics from polyethylene, silicone, epoxy, and vinyl resins. Other types of foaming agents, such as bicarbonates, produce carbon dioxide.
