Product 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.

HANDLING and STORAGE               
LYR1716 Polyol and PU systems should be stored at room temperature below 25ºC in sealed drums.Agitate contents before use particularly after long standing.Precautions should be observed to avoid prolonged or repeated skin contact with the products or its introduction in or near to the eyes.If skin contact occurs all contaminated clothing should be removed and the effected skin area wiped with a cloth or paper towels saturated with ethanol or equivalent solvent followed by washing with soap and water.Goggle or eye shields should be worn when there is a danger of splashing or eye contact.With the exercise of such care LYR1716 System should not present any undue hazard to health under normal working conditions(Protective clothing and eye protection is recommended when handling Polyol).
