Neoprene is slightly higher in price than general purpose synthetic rubbers, but its resistance to ozone, oil and chemicals override the cost differential. The average cost of neoprene is $3,500 to $4,000 per ton. It is one of the best all-purpose elastomers where resistance to ozone, sunlight, oxidation and many petroleum derivatives are of prime importance. Added advantages include good resistance to water, many chemicals and good resilience characteristics and tensil strength properties. Neoprene is generally attacked by strong oxidizing acids, esters, ketones, chlorinated, aromatic and nitro hydrocarbons.
