Ratio of (A+C) and B material	100/84~86	Moulding density(g/cm^3)	0.35~0.40
Material temperature (^oC)	40~45/38~42	Hardness(23ºC)	50~60C 33~42A
Cream time (s)	6~8	Tensile strength(MPa)	≥2
End of rise time (s)	40~50	Elongation(%)	≥300
Free rise density (g/cm^3)	0.18~0.22	Tear strength(kN/m)	≥8
Metal mold temperature (^oC)	45~55	Flexing resistance(23ºC)	80,000 times no crack

• 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)

• These physical data are acquired by testing a sample of 6mm thick.
• Data listed above are just for reference. The detailed data are subjected to practical operation. Please contact us if other physical properties are essential.
