    Significance and Use

    3.1 There are many different antidegradants available for use in the rubber industry.

    3.2 This classification of the various materials covers their chemical structure along with a brief reference to their overall use and their properties.

    1. Scope

    1.1 This classification covers antidegradants used in rubber and where appropriate defines their important chemical and physical characteristics for use in rubber.

    1.2 The general term “antidegradant” describes materials used in rubber to protect against the effects of oxygen and ozone. Materials that fall in this general category include both antioxidants and antiozonants.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
