Currently, macromolecular material has incorporated each corner of our daily life, arrives greatly household electrical appliance, little plastic in our hands. Primary raw material PE, PP of chinampa is exactly two kinds therein. But the fire frequently occurred allows people recognize gradually, and inflammability has become a key factor of restriction macromolecular material development. The a statistics of the U.S. shows: in some fire incidents, because sucking a large amount of toxic smogs of producing in burning of macromolecular material and the number of death by suffocation often accounts for more than half of fire fatality number, such as Osaka, Japan department store fire fatality 118 people in 1972, wherein lethal 93 people of toxic smoke, account for the 80% of total death toll. " West Brunswick " building fire of 42 layers, USA New York in 1980, dead 137 people, 125 fire fighters by toxic smoke smoked fall.
