• Properties: Chemically unsaturated, not stable to temperature changes (thermoplastic), readily oxidizable by mastication; soluble in acetone, carbon tetrachloride, and most organic solvents; refraction index 1,52; dielectric constant 2,5. Processed by calaendars and extruders; can be injection-molded with low sulfur and high accelerator. Cured by hot-molding or in open steam, bij temperatures from 120-150 /degree/ C after addition of 3% sulfur, 1% organic accelerator, 3% zinc oxide, plus fillers or reinforcing agents. The only factors of significance in vulcanization are the time of exposure to heat and the temperature used. /Crude (unvulcanized) natural rubber/ Hazardous Substances Data Bank (HSDB)

• Raw rubber dissolves (or at least swells very strongly) in many organic liquids such as benzene, petroleum ether, crude petroleum, and carbon tetrachloride. In contrast, vulcanized rubber can only swell because the chemical cross-liking prevents dissolution. Hazardous Substances Data Bank (HSDB)
