Description
DESCRIPTION
LYR1716 is a blend of polyols,surfactants,catalysts,fire retardant and CFC free blowing agent.The polyol offers increased resistance to burning and spread of flames.The polyol blend is specifically developed as one part of a two components system for rigid polyurethane insulated pannel processed by filling with dispensing machine or by mutual pouring in place.
It is widely used in manufacture of composite board,sandwich panel,inorganic panel applied for door,outwall,roofing,air condition duct and so on. 
The foam of this PIR system has a good flowability, low thermal conductivity, good dimensional stability and excellent fire resistance properties.
