KW - De-proteinization KW - Natural rubber latex KW - Properties N2 - The preparation, properties and the variations of properties during the natural storage and application of De-Proteinized Natural Rubber Latex (DPNRL) were studied. The results showed that the preparing conditions are affected by the enzyme dosage, and the incubating time and temperature. The physical and film forming properties of DPNRL prepared are good, whereas the mechanical stability time (MST) and heat stability time (HST) are low and are needed be raised by the addition of stabilizer ER -
