Physical properties

Items	Molded Density(g/cm³)	Hardness(shore A)	Tensile strength(Mpa)	Elongation(%)	Tear Strength(kN/m)	Flexing resistance (Break length 4mm) (-20°C 40,000times)
Physical properties	0.40-0.55	45-65	4.0-5.5	520-650	16-26	No crack

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.
