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. High flame performance and a low dielectric constant keep our equipment safe and data moving quickly. THE SOLUTION The manufacturer worked with Avient to identify alternatives to FEP insulation that would meet requirements in their data cable.

To provide a secure grip for safety and usability, the company planned to overmold a thermoplastic elastomer (TPE) onto the handle and other selected areas of the sprayer. Gripping feel = safety and usability for customers: Hand grips created from overmolded OnFlex-S TPE provide excellent anti-slip performance even when wet.

Global reach includes the capability of remote technical services and data management, allowing users to interrogate their systems on an intranet as well as getting Avient support remotely. The control system is flexible, allowing users access to a range of data management functions. Network capable Data acquisition and SPC Web enabled Touch screen controller User login security Gravimetric functions Custom configuration Remote access functions QUICK CHANGEOVER RESERVOIR The reservoir cassette is a key operating element of the FlexOne unit, allowing users to quickly changeover color.
