Product Description

HD-9330 / HD-1889

Characteristics: Polyether type, low density, low hardness, high resilience

Application: For Insole,Mid-sole

Typical properties of PU resin:

Name of products	Appearance	Density(g/cm^3@40^oC)	Viscosity(mPa·s @40^oC)	Package Size(kg/drum)
HD-9330(POL, A)	Cream liquid	1.13~1.18	1500~2500	17 / 210
HD-1889(ISO, B)	Liquid	1.18~1.20	50~300	19 / 225
C008	Liquid	1.18~1.20	350~450	5
C005 (	Liquid	1.18~1.20	350~450	5
H	Liquid	1.18~1.20	350~450	10

Processing:
Please preheat materials at 60~70ºCfor 6~10 hours before processing. Then mix fully the whole drum of POL and C008, C005 and H according to the following table. Finally, respectively transfer POL and ISO to their corresponding tanks. Later, use the formulation below. And finally, make the finished products.

HD-9330 (POL, A)	HD-H/g	water/g	C008/g	C005/g
17 kg(one drum)	0	100~220	270	Según necesitan
210 kg (one drum)	0	1250~2800	3300	Según necesitan

Reactivity and product performance:

Test Items	Reactivity parameters	Test Items	Product performance
Ratio of (A+C) and B material	100/50~60	Moulding density(g/cm^3)	0.3~0.4
Material temperature (^oC)	40~45/38~42	Hardness(23ºC,Shore C)	20~45C 10~30A
Cream time (s)	4~6	Tensile strength(MPa)	≥1
End of rise time (s)	15~25	Elongation(%)	≥300
Free rise density (g/cm^3)	0.12~0.16	Tear strength(kN/m)	≥7
Metal mold temperature (^oC)	45~55	Flexing resistance(23ºC)	150,000 times no crack
Demould time(min)	3~5	DIN abrasion resistance(mm3)

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).
