Silica-Reinforced Deproteinized Natural Rubber | IntechOpen
Deproteinized natural rubber is a purified form of natural rubber, which is characterized by its very low nitrogen, ash, and volatile matter contents compared to the commercial natural rubber. Similar to natural rubber, DPNR can be reinforced with carbon black as well as silica according to the intended applications.

cially the protein removal. The deproteinization process of natural rubber yields a rubber with reduced protein content significantly as well as low ash and volatile matter which is known as deproteinized natural rubber (DPNR). The deprotein-ization process can be carried out with natural rubber latex via enzymatic treat-ment [38–40] or urea treatment [41, 42].

2.3. Deproteinized natural rubber. Studies on deproteinized natural rubber (DPNR) were initiated due to protein allergy issue on dipped rubber products. DPNR latex is prepared by removing the protein layer covering the rubber particles . The protein layer can be removed by centrifugation, enzymatic degradation or irradiation [24, 25]. Since the protein layer actually acts as stabilizer, surfactant is added during deproteinization.
