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.

You can be certain that PolyOne meets or exceeds the material safety data reporting requirements of your country or region. Healthcare equipment manufacturers must meet explicit technical and regulatory standards so that practitioners can deliver effective diagnoses and treatments. Sustainability metrics represent 2018 data or 12-month approximate values based on available data from reporting facilities and are often made in reliance on third-party supplier information.

Data is reported in pounds per linear inch (pli). The list is far from being comprehensive of the available technical solution from our work. Data is reported in pounds per linear inch (pli).

Thus far, the insert molding data presented here is very encouraging and it is determined that these novel TPEs will exceed expectations in two-shot molding environments as well. The technical contributions of Joe Gerkhardt, Sr. R&D Chemist in generating a bulk of the presented data are hereby acknowledged.
