Description:

Chloroprene is the first synthetic rubber developed commercially and exhibits generally good ozone, aging and chemical resistance. It has good mechanical properties over a wide temperature range.

Advantages:

Can be use in paraffin base mineral oil with low DPI, silicone oil and grease, water and water solvents (up to 250°F), refrigerants, ammonia and carbon dioxide.

Disadvantages:

Cannot be used with aromatic hydrocarbons, chlorinated hydrocarbons, ketones, esters and ethers.
