FR Non-Toxic Compounds for Fibers, Coated Fabric, Film & Sheet

A recent innovation of an inexpensive Intumescent (char forming compound) has been developed and soon to be marketed for use in coated fabrics.

In addition to inexpensive, the material is a drop-in replacement for PVC, is 100% non-toxic (no halogens or bromines) and can be extruded as films, sheet, profiles, coated fabrics and molded into shapes with a V-0 rating and has passed CA-19 and ASTM E84 (b) and may pass the (a) version in an upcoming test. The material can be made either flexible or rigid in a wide range of durometers.

Other intumescents compounds are being evaluated to NFPA 286 in corner burn testing.

Yet, another compound for potential use as a bonding film/sheet has passed a a 60 second vertical burn test between two layers of woven carbon fiber fabric and two layers of a woven glass fabric with no dripping. an unsupported sheet has also passed the same 60 second vertical bun test with no flaming drips.

An earlier vapor phase material with non-detectable toxicity can be made into textile fibers and yarns.

The future of plastics to meet extraordinary fire needs are bright with new fire retardant and fire resistant compounds emerging.

Note: I can extended this further summary, but need to leave now for a flight. Back later in the week.
