    The role of petroleum waxes in the protection of rubber The use of petroleum waxes to protect or assist in the protection of double bonded elastomers from the destructive effects of ozone has long been known, while the mechanism by which these petroleum hydrocarbons fulfill their protective functions has more recently been elucidated, and can be followed by the analytical technique of high

    use of waxes for ozone protection in rubber

    rubber, wax provides little or no resistance to sunlight (or UV) deterioration. Petroleum waxes do provide protection against ozone attack of rubber parts. It’s important to know the difference between ozone and UV degradation if parts come back from the field with surface cracking.

    Considering its mechanism, the wax is getting in reaction with the ozone or the decomposed product due to the ozone, at the surface of rubber product. Apart from helping in diffusion process, the wax material itself has a protection effect, creating film on rubber surface thus closing it from oxygen and ozone, however, sole usage of wax under

    Sealing wax was used to close important documents in the Middle Ages. Wax tablets were used as writing surfaces. There were different types of wax in the Middle Ages, namely four kinds of wax (Ragusan, Montenegro, Byzantine, and Bulgarian), "ordinary" waxes from Spain, Poland, and Riga, unrefined waxes and colored waxes (red, white, and green).

    Standard Classification for Petroleum Waxes for Use in Rubber

    4.1 Petroleum waxes in rubber compounds are commonly used to provide protection from degradation by ozone under static conditions, that is, when there is little or no flexing of the rubber products. The mode of action for this protection is ( 1 ) migration of the wax through the rubber to the surface of the product and ( 2 ) the formation of an

    Ozone Resistance - an overview

    Static protection is provided by petroleum waxes, usually paraffin and/or microcrystalline waxes. The waxes work by blooming to the rubber surface to form a physical barrier to ozone attack. The choice of wax or wax blend is based upon migration temperature where mobility and solubility of the wax in the rubber are balanced so that sufficient

    Microcrystalline wax - Wikipedia

    Microcrystalline waxes are a type of wax produced by de-oiling petrolatum, as part of the petroleum refining process. In contrast to the more familiar paraffin wax which contains mostly unbranched alkanes, microcrystalline wax contains a higher percentage of isoparaffinic (branched) hydrocarbons and naphthenic hydrocarbons.

    Paraffin waxes (petroleum), hydrotreated. A complex combination of hydrocarbons obtained by treating a petroleum wax with hydrogen in the presence of a catalyst. It consists predominantly of straight chain paraffinic hydrocarbons having carbon numbers predominantly in the range of about C20 through C50.
