Polychloroprene is one of the best general-purpose synthetic rubbers, although its use in seal applications is somewhat limited at the present time.
Its main advantage is its excellent resistance to weather-aging.
It is also superior to natural rubber in performance at higher temperatures, but tends to harden or stiffen at low temperatures and may also crystallize at low temperature if under stress.
This tendency can be reduced by the correct choice of polymer type and by compounding.
