continues to advance its fiber colorant technology, enabling textile manufacturers, converters and brands to increase sustainability, operational efficiencies, and market response rates to drive their success in the global textile industry.

While we have collected water data from our manufacturing facilities since 2012, increased water data accuracy allows us to better understand our water sources, withdrawal rates, and discharges.

Mevopur™ Nucleation Additive Concentrates help produce thinner walls in polyolefin applications while maintaining mechanical properties and reduce Moisture Vapor Transmission Rate (MVTR) in HDPE.

In addition, this unique technology increases production efficiency by eliminating the coextrusion process used to manufacture striped catheters, as well as reducing material usage and scrap rates.

The materials are formulated to meet applicable UL flame rating standards while also providing anti-yellowing performance, chemical resistance and outstanding light diffusion.

These include:  •    Improved bottle mechanical strength •    Reduced stoppages, blowouts, and scrap rates •    Reduced energy consumption during the bottle blowing process

Geon Fiberloc composites include UL, CSA and NSF rated grades, and offer outstanding resistance to chemicals and corrosion at pressures up to 650 psi.

The new ECCOH™ XL Cross-Linkable Solutions for photovoltaic cables are REACH compliant and rated for permanent outdoor use with good UV and weather resistance, passing Arrhenius lifetime prediction tests as per IEC 60216-1.
