Explosive limit:

vol% in air: 1.90

Odor:

Pungent, ether-like odor

Experimental Properties:

Vulcanized with metallic oxides rather than sulfur; resistant to oils, oxygen, ozone, corona discharge, and electric current; isocyanate-modified form has high flame resistance.|Brittle point: -35 °C; softens @ approximately 80 °C|Polymerizes at room temperature unless inhibited with antioxidants.|Per cent in saturated air: 28 @ 25 °C; conversion factors: 1 mg/l approximates 276.5 ppm and 1 ppm approximates 3.62 mg/cu m @ 25 °C, 760 torr.|RAPIDLY OXIDIZES TO FORM PEROXIDES AND ACIDIC MATERIALS.|VAPOR PRESSURE: 300 MM HG @ 32.8 °C|Brittle point: -35 °F; softens: @ approx 80 °F

Air and Water Reactions:

Highly flammable. Slightly soluble in water.

Reactive Group:

Hydrocarbons, Aromatic

Reactivity Alerts:

Highly Flammable

Reactivity Profile:

CHLOROPRENE emits highly toxic fumes of chlorine gas when heated to decomposition. Autooxidizes very rapidly with air and, even at 0° C, produces unstable peroxides that catalyze exothermic polymerization [Bretherick, 5th ed., 1995, p. 507]. This reactivity is greatly slowed by presence of an inhibitor.

Peroxide Forming Chemical:

Chloroprene|A: Compounds that form explosive levels of peroxides without concentration|Clark, Kelly|Autoxidizes rapidly with air, even at low temperatures. See Bretherick's and references within.|Bailey, H. C., in Oxidation of Organic Compounds-I, ACS No.75(Gould,R.F.,Ed.),138–149,Washington, ACS, 1968

Autoignition Temperature:

440 °C

Ionization Potential:

8.79 eV

Flammable Limits:

LOWER FLAMMABLE LIMIT 4.0%; UPPER FLAMMABLE LIMIT 20.0%.|Class IB Flammable Liquid: Fl.P. below 73°F and BP at or above 100°F.

Physical Dangers:

The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.
