In fact, the supplier specializes in automotive interiors and was encountering production issues with certain vinyl materials. Finally, the material was formulated to mimic the plush look and dry feel of leather. Additionally, it was projected that scrap rates were reduced by at least 10% over competitive materials.

MEETING FR GOALS IN DATA CABLES WITH AN ALTERNATIVE TO FEP Maxxam FR materials can provide cost savings and improved processing capabilities when used in category 5e cables and above. Not only is the material costly, it can also be challenging to process and use in thin wall cable applications. After Avient delivered test data for pair combinations and the manufacturer’s team completed material trials, they were able to replace FEP with Maxxam FR material in four out of four insulation pairs.

Tested against commonly used wet grip materials, the Versaflex XP 2850 material demonstrated exceptional wet kinetic COF performance— showing more than a 100% improvement over the competition—and better dry COF performance as well. In addition to enhanced tackiness, this specialty material offers excellent abrasion and UV resistance, plus a skin-safe, non-abrasive finish. Processing conditions can cause material properties to shift from the values stated in the information.

Finely dispersed TiO2, and color distribution with precision dosing, drive consistency, material efficiency, and sustainable consumption. Processing conditions can cause material properties to shift from the values stated in the information. Avient is a premier provider of specialized and sustainable material solutions and services that transform customer challenges into opportunities.

But specific materials with exceptional tensile and burst strength are needed to successfully retrofit these existing pipelines to accelerate conversion and prevent further environmental damage. These materials must be able to withstand the effects of hydrogen transfer without contaminating the energy source or harming the pipe in order to keep the energy system safe. The reinforcement material increased breaking efficiency, resistance to long-term creep, elevated temperatures, and cyclical strain- based fatigue.
