Abstract:
The natural rubber latex of the present invention in which phospholipid contained in the latex is decomposed, particularly the natural rubber latex in which it is decomposed by enzyme treatment with lipase and/or phospholipase at a temperature of 70° C. or lower is excellent in a processability, and in the natural rubber thereof and the rubber composition using the same, the physical properties such as an anti-aging characteristic, a tensile strength and an abrasion resistance are sufficiently maintained. Accordingly, the natural rubber of the present invention can be used as an excellent member for a tire.
