Manufacturers working with sulfur-cured and peroxide-cured rubber compounds can improve their processes and product performances by using Sulfron, which is a modified Twaron aramid. Sulfron can add value to a wide range of applications, particularly tires and rubber-based products. Sulfron reduces hysteresis, heat build-up and abrasion, while improving flexibility, tear- and fatigue-resistance properties, and rolling resistance by up to 25%.

- Reduces frictional energy and heat build-up
- Reduces hysteresis
- Reduces rolling resistance
- Improves cut, chip, and chunk resistance
- Improves product durability
Sulfron can be used by manufacturers to reduce the hysteresis of carbon-black-filled compounds and of compounds containing both carbon black and silica. Manufacturers can mix Sulfron with the compound at elevated temperatures to reduce filler-filler interaction and limit the Payne effect. To obtain maximum performance, Sulfron and carbon black should be mixed at a temperature in the range 150-165 ºC for at least 90 seconds. Ultimately, Sulfron improves rubber compounds by increasing durability and improving heat resistance. When used in vehicle tires, the lower rolling resistance can lead to better fuel efficiency. Sulfron is suitable for compounds containing both natural and synthetic rubber, and can be adjusted to different manufacturing requirements.
