Product Description

HD-4160 / HD-2122T
Characteristics: Medium to low density, medium hardness.
Application: For casual shoes.
Typical properties of PU resin:

Name of products	Appearance	Density (g/cm3 @40oC)	Viscosity (mPa·s @40oC)	Package Size (kg/drum)
HD-4160(POL, A)	Liquid	1.03~1.18	800~1050	18 / 220
HD-2122T(ISO, B)	Liquid	1.13~1.20	100~300	20 / 235

Processing:
Please preheat materials at 60~70ºC 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.

HD-4160(POL, A)	HD-H/g	water/g	Catalyst HD-C-008/g	Other additive/g
18 kg(one drum)	0	50~55	230~250	It depends
220 kg(one drum)	0	600~670	2800~3100	It depends

Reactivity and product performance:

Test Items	Reactivity parameters	Test Items	Product performance
Ratio of (A+C) and B material	100/98~101	Moulding density(g/cm3)	0.38~0.45
Material temperature (oC)	40~45/38~42	Hardness(23ºC)	60C~70C 40A~50A
Cream time (s)	5~7	Tensile strength(MPa)	≥3
End of rise time (s)	20~30	Elongation(%)	≥300
Free rise density (g/cm3)	0.20~0.25	Tear strength(kN/m)	≥13
Metal mold temperature (oC)	50~55	Flexing resistance(23ºC)	40,000 times no crack
Demould time(min)	3~4	DIN abrasion resistance(mm3)	≤600

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)
