In China,the heat stabilizers. production is the sa e too,and the lead-salt stabilizers are highly poisonous,environ ent pollution,and difficult to ix.The usage of lead-salt stabilizers is ore than 65% of thetotalstabilizers in China,thesituation isso unreasonablethat it. s of the ost i portance to develop highly effectivestabilizers and other stabilizers.
