    use of waxes for ozone protection in rubber

    The basic reasoning behind blended waxes can be stated as follows: Ozone attacks rubber between the temperatures of 25 °F (-4°C) and 130°F (54°C). To protect the rubber, there must be a wax film present on the surface of the rubber regardless of the ambient temperature.
