Celanese Develops New XT Grades for Superior Toughness by Expanding its Hostaform® POM S Series

Celanese Corporation, the global technology and specialty materials company, celebrated 50 years of the Celcon®/ Hostaform® acetal copolymer (POM) product line by expanding its S series of impact modified POM to include two new extreme toughened XT grades for applications that require exceptional impact strength and flexibility in demanding environments.
Hostaform XT 20 and XT 90, which complement and expand the existing Hostaform S series, are designed to compete in application areas previously reserved for highly modified impact modified acetal copolymers and homopolymers, thermoplastic polyurethanes and impact modified polyamide (PA) resins.

"Hostaform S and XT grades can outperform all impact modified POMs available today," said Mervyn Cox, global Hostaform POM product marketing manager - Celanese. "They can help designers push the boundaries in a broad range of fastener, buckle, dampening gear and housing applications that are used in a variety of industries, including automotive, consumer and industrial."

This is achieved with proprietary Celanese POM hybrid technology that allows lower levels of impact modifiers to be used while enabling significant improvements in mechanical properties and weld-line strength retention vs. competitive impact-modified POM.
Hostaform S and XT grades offer inherent benefits - resilience, humidity independence and an expansive operating temperature – clear advantages vs. impact modified PAs.
"In addition, lower modifier levels enhance tribology - slip and wear and chemical resistance characteristics," added Cox.
The Celanese hybrid technology enhances the attributes of Hostaform XT POM to include:
  • Improved toughness to strength ratio - potential weight saving
  • Enhancement mechanical Properties - broader design freedom
  • Superior weld line strength - simplifies design
  • Humidity independent - low moisture absorption
  • Superior creep characteristics - improves long-term part performance
  • Enhanced thermal stability - improves productivity robustness

Arkema Unveils Bio-based Pebax® RNew 80R53 Grade for Ski Boots at ISPO Munich

At ISPO 2014, Arkema presented its latest Pebax® Rnew grade : Pebax® RNew 80R53, a grade that goes beyond the limits of thermoplastic elastomers. This new rigid bio-based Pebax® opens up the scope of ski boot design combining light weight, astonishing responsiveness to skiers’ movements, and creativity in decoration. ISPO Munich held from January 26 to 29, is the European trade fair for winter and outdoor sports that offers a showcase for the latest trends in ski equipment.

Pebax® Rnew 80R53 is 50% more rigid than existing Pebax® grades, already well-known for several years as reference materials for bothalpine touring and cross-country ski boots.
It retains the key Pebax® characteristics and environmental qualities that appeal to sportsmen and women: produced from renewable raw materials with more than 90% bio-based content, lightweight, renowned long-term UV resistance and offering great creativity for novel designs, it maintains perfect quality and performance under extreme cold conditions.

In addition, thanks to its rigidity and outstanding processability, Pebax® Rnew 80R53 allows unequalled design freedom for thinner and even more lightweight and dynamic shoes.
It stands out as the material of choice to achieve a perfect balance between light weight and the downhill performance required by more and more sportsmen and women experiencing free-ride skiing.
