    Specific polyester polyol of which the major ingredients include phthalic anhydride and diethylene glycol. It is a clear,viscous liquid under room temp. XCPA-195 is mainly used for rigif foam in construction insulation and icebox,with the addition of about 10-30%, can maket the rigid foam reach a flame retardant grade of B2 .    Photos forrigid foam :         The product have a staorage life of 9 months a room temperature when stored in the original unopend containers. Opened containers have to be closed immediately and the material should be consumed within a short period time . Tt normally used with the polyether polyol in ab appropriate ratio to make the rigid foam,  which is good in intensity and hardness.
