Sasol Wax is the leading specialist in innovative wax technology.
at a glance
Paraffin wax is the major raw material for the production of candles and a wide variety of other applications such as rubber & tires, chipboard, food-processing and packaging, pharmaceuticals, cosmetics, inks paints & coatings, textiles as well as in road construction and many more. For many decades Sasol Wax has focussed on the development of paraffin waxes and specialty wax blends for a lot of different industries. Due to the wide range of our products, we are able to offer solutions suitable for almost all production processes. Micro and macro crystalline waxes are renown for a broad spectrum of applications. Their use ranges from rather simple pplications to process oriented tailor-made products for state of the art production equipment. Specialties are created for innovative solutions. Refined paraffin waxes are mixtures of saturated hydrocarbon, purified by modern, environmentally friendly technologies. All our products are constantly monitored by a stringent quality control and are non-toxic. Their environmental properties are characterized by good biodegradability and non-cumulative effects.
Paraffin waxes in the rubber and tire industry
The greatest naturally occurring threats to tires and all other synthetic and natural rubbers are ozone and ultraviolet (UV) light. Ozone is an odorless gas and part of the atmosphere. Highest levels are found in cities and industrialized centers. UV light protection of rubber goods is preferably achieved by the addition of carbon black. This gives tires the typical colour. also some high performance chemical UV absorber are used. UV stabilizers are generally used up while they perform their function. Tires turn from black to grey while the carbon black is loosing its function and the degradation of the rubber material takes place. This makes the rubber turn brittle and leads to the formation of cracks. For ozone protection manufacturers add waxes to their compounds at common dose rates between 1 and 3 phr. During operation the tire bends and fl exes. This activates the migration of the antiozonant wax to the surface of the tire forming a thin, protective wax fi lm. This migration intensifi es with increasing temperature. Ozone attack on rubber compounds occurs in a temperature range between 0 °C and 55 °C. Below this temperature range the ozone does not have a high enough activation energy to react with the rubber. Above it ozone levels in the atmospheredecrease to minimal levels. Antiozonant waxes are complex and thoroughly designed blends. They consist of unbranched straight chain n-paraffi ns as well as branched iso-paraffi ns of different chain length. Compared to iso-paraffi ns n-paraffi ns with a similar number of carbon atoms have a greater migration tendency. Generally the 'solubility' of antiozonant waxes in rubber increases with decreasing molecular weight (carbon atom number). Paraffi n waxes with high n-paraffi n content provide rapid protection for newly produced goods. Micro waxes especially with high molecular weight iso-paraffi ns guarantee slow release and long lasting protection. Antiozonat waxes with a high micro wax content are used e. g. for tire sidewall protection. Additionally antiozonant waxes may act as a transport medium for other antiozonants and antioxidants (like amines and phenolic derivates).
The greatest naturally occurring threats to tires and all other synthetic and natural rubbers are ozone and ultraviolet light. VaraZON 5998 is the tire industries first choice when it comes to ozone protection. Especially in a temperature range of 10-50 °C the protection against ozone attack is outstanding. Additionally with its fine balance between straight and iso components an excellent migration behaviour is achieved. This ensures the formation of a thin layer of wax on the surface of the tire. Quick acting and long lasting. VaraZON 5998 features UV-protection and good processability as well as anti blocking behaviour.
