General-purpose Chloroprene Rubber Latex (CRL50LF Type)
I. Property Features
The CRL50LF type rubber latex is a kind of anionic chloroprene rubber latex with moderate crystallinity and water dispersion system, which is manufactured by emulsion polymerization of chloroprene monomer and by using Nairit polymerization process technology. The CRL50LF type rubber latex is also a kind of general-purpose chloroprene rubber latex and can be solidified into films rapidly and may form dry films of high strength if being dried under a temperature of about 130℃. It has pretty good storage stability, mechanical and chemical stability, as well as climate resistance, ageing resistance, heat resistance, non-inflammability and other features of chloroprene rubber. And it also has the same applied properties as DuPont842A of the US.
