Performance & Savings For Polypropylene Compounds

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.


Benefits Of Ultranox® 800 Series

  • Stabilization cost savings up to 50% due to ULTRANOX® 800 series performance and addition rates
  • 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
