The crystal structures and thermal decompositions of trihydrazinotriazine and biurea
thesis
posted on 2018-10-30, 15:21 authored by Paul R. RussellTrihydrazinotriazine (THT) and biurea are both used industrially
as blowing agents for expanding certain types of polymers. The term
‘blowing agent’ is applied to any substance which can produce pores or
cells in a polymeric material. There are two classes of blowing agent,
physical and chemical. Physical blowing agents depend on a change of
state of the substance to produce the cells e.g. the expansion of a
compressed gas or evaporation of a liquid. Chemical. blowing agents
depend on the evolution of gases by thermal decomposition to produce the.
cells. It is to this latter class that THT and biurea belong. [Continues.]
