Product Description

HD-8090-1 / HD-2400
Characteristics: Ultra-low density, ultra-high hardness and available flexibility.
Application: For high heel shoes or platform shoes.

Typical properties of PU resin:

Sample	Appearance	Density(g/cm^3@25^oC)	Viscosity(mPa·s @40^oC)	Package Size(kg/drum)
HD-8090-1(POL, A)	Cream Liquid	1.13~1.18	1800~2500	18 / 220
HD-2400(ISO, B)	Liquid	1.18~1.20	50~250	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-8090-1	Hardener/g	water/g	catalyst/g	Post-catalyst	Other
18 kg(one drum)	400	90	300	100	It depends
220 kg(one drum)	4900	1100	3700	1200	It depends

Reactivity and product performance:

Test Items	Reactivity parameters	Test Items	Product performance
Ratio of (A+C) and B material	100/125~127	Moulding density(g/cm^3)	0.25~0.35
Material temperature (^oC)	38~42/35~40	Hardness(23ºC,Shore C/A)	85~95C
Cream time (s)	5~8	Tensile strength(MPa)	≥3
End of rise time (s)	20~30	Elongation(%)	≥100
Free rise density (g/cm^3)	0.11~0.15	Tear strength(kN/m)	≥15
Metal mold temperature (^oC)	45~55	DIN abrasion resistance(mm3)	≤300
Demould time(min)	3~4

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).
