Isocyanate 100-150 parts by weight

5.Application Guidline
made according to the data presented in this technical information on the casting machine, high and low pressure.The temperature of the forming equipment is 30 - 35 C°

6.Typical Physical Properties

Property	Unit	Value
Density	kg/m3	≥50
Closed cell content	%	90
Coefficient of thermal conductivity	W / m K	0.026
Compressive strength (10% deformation)	Kpa	≥150

7.STORAGE OF MATERIALS
The materials are sensitive to humidity and partially used drums should be tightly sealed  to prevent the ingress of moisture.
Polyol Blend
The Polyol blend has a shelf life of six months from date of manufacture when stored in doors at temperatures of 20-30°C.The Polyol blend should be thoroughly mixed before use.
Isocyanate
The Isocyanate has a helf life of one year from date of manufacture when stored indoors  at temperatures of 20-30°C.Avoid storage temperatures of below 0°C (as some crystallization may occur) or above 50°C (as formation of insoluble solids may occur).
