Typical properties of PU resin

Name of products	@40ºC Appearance	Density (g/cm3 @40oC)	Viscosity (mPa·s @40oC)	Package Size (kg/drum)
HD-5005(POL, A)	Deep Colour liquid	1.03~1.13	900~1200	18 / 220
HD-1900(ISO, B)	Liquid	1.08~1.20	350~450	20 / 235

Processing
Please preheat materials at 60~70 ºC for 6~10 hours before processing. Then mix fully the whole drum of POL and other
additives according to the following table. Finally, respectively transfer POL and ISO to their corresponding tanks.

Reactivity and product performance

Test Items	Reactivity parameters	Test Items	Product performance
Ratio of (A+C) and B material	100/89~91	Moulding density(g/cm3)	0.45~0.55
Material temperature (oC)	40~45/38~42	Hardness(23ºC)	55C~70C 35A~50A
Cream time (s)	4~6	Tensile strength(MPa)	≥4
End of rise time (s)	15~25	Elongation(%)	≥350
Free rise density (g/cm3)	0.25~0.28	Tear strength(kN/m)	≥13
Metal mold temperature (oC)	45~55	Flexing resistance(23ºC)	4  40000 times no crack
Demould time(min)	2.5~3.5	DIN  DIN abrasion resistance(mm3)	≤450

The ratio based on the best value varies with the type and quantity of added paint additives.
The free rise foam density varies with the seasonal variation (temperature, humidity)
