Sulfron

Sulfron is a modified Twaron aramid. Used as a compounding ingredient, it improves the properties of sulfur-cured and peroxide-cured rubber compounds. It reduces hysteresis, heat build-up and abrasion, while improving flexibility, tear- and fatigue-resistance properties.

It can be used to reduce the hysteresis of carbon-black-filled compounds and of compounds containing both carbon black and silica. As the Sulfron 3001 is mixed with the compound at elevated temperatures, intermediate reaction products are formed that interact with the carbon-black particles, thereby reducing the filler-filler interaction (improving the Payne effect). The result is a compound with reduced frictional energy and thus improved hysteresis properties.

With carbon black, this reaction takes place at elevated temperatures of between 140°C and 160°C. It is suitable for compounds containing both natural rubber (NR) and synthetic rubber (SR). Tires that contain Sulfron are more durable and longer lasting, with better fuel efficiency (thanks to their lower rolling resistance), without compromising performance.

Among other applications, Sulfron is suitable for improving truck/bus (TB), off-the-road (OTR) and agricultural tires. In addition, Sulfron brings benefits to applications related to other rubber products and compound reinforcements as well.
