Neoprene/Chloroprene Rubber -CR

Neoprene, a synthetic rubber produced by alpha-polymerization of chloroprene (i.e., 2-chloro-1,3-butadiene) as the main raw material.It has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance and chemical reagent resistance.
Availability:
Quantity:

Neoprene, a kind of synthetic rubber obtained by the alpha-polymerization of chloroprene, which is essentially based on 2-chloro-1,3-butadiene as the major raw material.It features good physical and mechanical properties along with resistance toward oil, heat, flame, sunlight, and ozone adequately. It also resists acids and alkalis as well as chemical reagents. Has high tensile strength, elongation, and reversible crystallinity, good adhesion.  Aging and heat resistance.  Excellent in oil resistance and chemical corrosion.  Weather resistance and ozone aging resistance is ethylene propylene rubber and butyl rubber afterward.  Heat resistance is equivalent to NBR, with a decomposition temperature of 230-260℃; short-term resistance is 120-150℃, used for long periods at 80-100℃, where it also has some flame-retardant properties.  Excellent corrosion resistance to inorganic acids and alkalis. Herchy Rubber based on the abundant knowledge in rubber technology and extensive word-wide distribution channels. Exported to more than 15 countries USA, Russia, Brazil, Argentina, Korea, Germany, Italy, Spain, Australia, India, etc.Neoprene, a synthetic rubber produced by alpha-polymerization of chloroprene (i.e., 2-chloro-1,3-butadiene) as the main raw material.It has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance and chemical reagent resistance.


Has high tensile strength, elongation and reversible crystallinity, good adhesion.  Resistant to aging and heat.  Excellent resistance to oil and chemical corrosion.  Weather resistance and ozone aging resistance is second only to ethylene propylene rubber and butyl rubber.  Heat resistance is comparable to NBR, decomposition temperature 230-260℃, short-term resistance 120-150℃, long-term use at 80-100℃, with a certain degree of flame retardancy.  Good corrosion resistance to inorganic acids and alkalis.
