Benefits Of ULTRANOX™ 800 Series


Introducing The ULTRANOX™ 800 Series From SI Group

Polypropylene systems have high stabilization demands. In order to meet increasing melt, color and storage performance standards SI Group™ has launched the ULTRANOX™ 800 antioxidant series.
Standard stabilization systems have lacked innovation and not kept pace with increasing material science and end product requirements. In order to address this gap, SI Group™ has developed three high performance antioxidants as part of the ULTRANOX™ 800 product line. Designed for applications that demand high temperature, extreme processing or enhanced color stability, ULTRANOX™ 800 products fulfill the evolving requirements of convertors.
- Superior product aesthetics from enhanced color control
- Increased throughput from better processing stability
- Supply security from a domestic world-class ISO certified manufacturing facility
- On-site technical support from SI Group's industry leading experts
- Stabilization cost savings up to 50% due to ULTRANOX™ 800 series performance and addition rates
