“The SABIC team provided support to enable us to develop our new Ultra-Protechtor fire blocker,” said Anthony Centofanti, chief executive officer and president, National Nonwovens. “This, combined with the outstanding performance of ULTEM fiber, allowed National Nonwovens to easily upgrade from aramid to create a truly high-end product that meets growing industry safety demands and provides aircraft manufacturers with an exceptional fire blocker technology.”
ULTEM Fiber Contributes to Cabin Safety and Comfort and Lower Operating Costs
ULTEM fiber is based on the company’s world-leading ULTEM resin, which delivers high heat resistance together with high flow, high ductility and strength to meet tough environmental conditions. This material, which meets the requirements of Federal Aviation Administration (FAA) FAR 25.853 regulations, features inherent flame retardance without additives or fillers that can give off volatile organic compounds (VOCs).
National Nonwovens gained key property improvements using ULTEM resin for its new Ultra-Protechtor fire blocker, including higher limited oxygen index (LOI) and lower heat release for safety, and low specific gravity and reduced moisture absorption for lighter weight solutions – reducing fuel consumption – which continues to be a main focus to the aerospace industry.
The SABIC material also contributes to the durability and softness of the Ultra-Protechtor fire blockers due to the inherent properties of the ULTEM resin.
“Whether it’s in the form of a resin, fiber or foam, aerospace grades of ULTEM resin have become a clear solution of choice for the most demanding applications,”
