Physical properties

Items	Molded Density(g/cm³)	Hardness(shore A)	Tensile strength(Mpa)	Elongation(%)	Tear Strength(kN/m)	Ross Flexing-90º (-10°C)	Williams abrasion (cc/php)
Physical properties	0.45-0.60	50-70	4.0-7.0	420-560	17-25	100,000times no crack	130-140

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.
