Synthetic leather substrates with water vapor absorption 2-8%, tensile strength 30-250 kg/cm2, and breaking elongation 30-150 % are manufd. by impregnating nonwoven fabrics with a rubber latex contg. a silicone emulsion, vulcanization accelerator, and heat sensitizer to accelerate coagulation off latex at 125-800C.
