CAS No.: 23111-00-4
Product introduction:NR-CL refers to chlorinated natural rubber, a chemically modified derivative of natural rubber (NR) obtained through chlorination reactions. The introduction of chlorine atoms onto the natural rubber backbone significantly enhances its polarity, chemical resistance, and film-forming properties. It is one of the most important industrial derivatives of natural rubber, widely used as a film-forming agent in coatings and adhesives
CAS No.:23111-00-4
NR-CL is a chlorinated natural rubber typically appearing as a white powder. It is prepared by reacting natural rubber with chlorine gas or chlorinating agents such as sodium hypochlorite . Chlorination can occur via both substitution and addition mechanisms, introducing chlorine at the allylic positions and across the carbon-carbon double bonds of the rubber backbone
Core Functions:
Film-forming agent in anti-corrosion coatings (marine paints, chemical-resistant coatings, traffic paints)
Additive in high-performance adhesives for rubber-to-metal bonding
Binder in printing inks and flame-retardant coatings
Research use in polymer modification and chlorinated elastomer development
