of NR. The major difference is that isoprene has no odor and, therefore, can
be used in the handlingo fcertain food products.
6.5.3 Neoprene
The maximum temperature that neoprene (CR) can be used under is
180–2008 F(82–938 C). Excellent service is experiencedincontact with aliphatic
compounds(methyl and ethyl alcohols, ethylene glycols, etc.), aliphatic
hydrocarbons, andm ostf reonr efrigerants.H owever,t he outstanding
properties of neoprene is its resistance to attack from solvents, waxes, fats,
oils, greases, and many other petroleum-based products. Dilute mineral
acids,inorganic salt solutions, and alkalies can also be handled successfully.
