This specification covers a chloroprene (CR) rubber in the form of sheet, strip, tubing, and molded shapes. These products have been used typically for parts requiring resistance to weather, such as window channels, bumper pads, chafing strips, and seals, for use from -40 to +100 °C (-40 to +212 °F), but usage is not limited to such applications. Each application, however, should be considered individually.
