Product Description

HD-4160KD / HD-1900
Characteristics: Medium to high density, medium to high hardness.
Application: For outsoles and direct injection shoes.

Typical properties of PU resin:

Name of products	Appearance	Density(g/cm3 @40oC)	Viscosity(mPa·s @40oC)	Package Size(kg/drum)
HD-4160KD(POL, A)	Deep Colour Liquid	1.03~1.18	1000~1500	18 / 220
HD-1900(ISO, B)	Liquid	1.08~1.20	350~450	20 / 235

Processing:
Please preheat materials at 60~70ºCfor 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-4160KD (POL, A)	Hardener HD-H/g	water/g	catalyst HD-C-008/g	other
18 kg(one drum)	0	35~45	220	It depends
220 kg (one drum)	0	600~670	2700	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)	0.45~0.55
Material temperature (oC)	40~45/38~42	Hardness(23ºC)	70C~80C 55A~65A
Cream time (s)	4~6	Tensile strength(MPa)	≥4
End of rise time (s)	15~25	Elongation(%)	≥350
Free rise density (g/cm3)	0.25~0.30	Tear strength(kN/m)	≥13
Metal mold temperature (oC)	45~55	Flexing resistance(23ºC)	40,000 times no crack
Demould time(min)	2.5~3.5	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).
