Correlation between the mechanical properties tested

Correlation between	Pearson’s correlation coefficient	P
K% and E%	−0.666 (strong negative relationship)	0.000*
K% and TE	−0.016 (no or negligible relationship)	0.939
K% and TS	0.746 (very strong positive relationship)	0.000*
E% and TE	0.319 (moderate positive relationship)	0.128
E% and TS	−0.898 (very strong negative relationship)	0.000*
TE and TS	−0.056 (no or negligible relationship)	0.794

*Correlation is significant at 0.05 levels. K%: Elastic recovery; E%: Strain in compression; TE: Tear energy; TS: Tensile strength
