Product Overview
Description
    Parker's Polychloroprene was 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.

    Used for Vacuum, General Purpose

    Heat resistance:
    • Up to approximately 121°C (250°F)
    • Cold flexibility
    • Down to approximately -40°C (-40°F)

    Chemical resistance
    • Paraffin based mineral oil with low DPI, e.g. ASTM oil No. 1
    • Silicone oil and grease
    • Water and water solvents at low temperatures
    • Refrigerants
    • Ammonia
    • Carbon dioxide
    • Improved ozone, weathering and aging resistance compared with nitrile

    Limited compatibility
