Typical processing parameters & Reaction parameter
Items | A/B Materials Temperature(°C) | A+C/B Mix ratio (by weight) | Cream Time(s) | End of rise time(s) | Free rise foam density(g/cm³) | Mold temperature(°C) | Demold time(min) |
Parameter | 30-35/35-40 | 100/105-107 | 8-10 | 60-70 | 0.22-0.32 | 35-45 | 7-9 |
The adding content of C-2 should be 270g±20/18kg
The adding content of water and hardener should be changed according to the reality
Physical properties
Items | Molded Density(g/cm³) | Hardness(shore A) | Tensile strength(Mpa) | Elongation(%) | Tear Strength(kN/m) | 168h,70°C,95%r.h.Hydrolysis Strength retention(%) |
Physical properties | 0.45-0.65 | 60-80 | 3.5-5.0 | 300-400 | 15-20 | >95 |
Demold time may be prolonged with the increase of sole thickness.
These physical date are acquired by testing a sample of 6mm thick.
Data listed above are just for reference, The detail date are subjected to practical production, If other request for Physical properties, please contact us.
