Rigid PU Pen Tane Blown PU Foam Insulation Polyol Mixture for Continous Sandwich Panel

Product Description

POLYOL BLEND DFR713F3

DFR713F3 is a formulated polyol consisting of,surfactants,catalysts,fire retardant and N-pen tane blowing agent. The polyol blend is specifically developed as one part of a two components system for rigid polyurethane insulated pannel with continuous process.
It is widely used in manufacture of composite board,sandwich panel,inorganic panel applied for door,wall,roofing,air condition duct and so on.
Panels manufactured with DFR713F3 system will display higher degree of compression and tensile strength in addition to its thermal and Eco-Efficiency performance.The higher percentage of closed cell is considered excellent barrier for air,water and noise.

HANDLING AND STORAGE               
DFR713F3 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 DFR713F3 System should not present any undue hazard to health under normal working conditions(Protective clothing and eye protection is recommended when handling Polyol).
