Product Description

Product Description

Typical properties of PU resin

Name of products	Appearance	Density(g/cm3@40oC)	Viscosity(mPa·s@40oC)	PackageSize(kg/drum)
HD-6090(POL, A)	CreamLiquid	1.13~1.18	2000~2500	18 / 220
HD-2040H(ISO, B)	Liquid	1.18~1.20	200~300	20 / 235

Processing

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

HD-6090(POL, A)	Hardener/g	water/g	catalyst/g	other
18 kg(one drum)	300	75~80	220	It depends
220 kg(onedrum)	3700	920~980	2700	It depends

Reactivity and product performance

Test Items	Reactivity parameters	Test Items	Product performance
Ratio of (A+C) and B material	100/97~99	Moulding density(g/cm3)	0.35~0.40
Material temperature (oC)	40~45/38~42	Hardness(23℃)	70~85C 55~75A
Cream time (s)	4~7	Tensile strength(MPa)	≥4
End of rise time (s)	20~30	Elongation(%)	≥300
Free rise density (g/cm3)	0.20~0.25	Tear strength(kN/m)	≥15
Metal mold temperature (oC)	45~55	Flexing resistance(23℃)	80,000 times no crack
Demould time(min)	3~4	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)
