ATLANTA — February 3, 2020— A new non-halogenated flame-retardant (FR) compound called PAL…VersaCHAR™ can achieve a new level of flame retardant performance as a coating for nonwovens and technical textiles.
It is being introduced by Dynamic Modifiers, a specialty compounder focused on custom polyolefin compounds and concentrates, based in Atlanta.
PAL…VersaCHAR has been tested to 1,950°C — the highest temperature to date — and shown to prevent all flaming drips of polymer. Char bodies form on the compound surface, protecting against flame creation and delaying heat transfer. Rapid self-extinguishing burn behavior protects any underlying substrate to which it is adhered.
In addition, the compound is light weight, at a specific gravity of 1.0, and 100-percent non-toxic in every respect, being free from heavy metals, halogens and VOCs.
Other properties include excellent cold crack performance, hydrophobicity, printability, extreme chemical resistance and the ability to be custom tailored for specific needs such as UV or antimicrobial performance, as volume warrants.
The compound is also very competitively priced.
In addition to its use as a coating, PAL…VersaCHAR compound can be produced as a flexible film or sheet and molded to shape or over-molded to most materials, including metal for corrosion resistance As a polymeric compound it can be cast or calendered and typical durometers from 80-99A for flexible-to-high rigid formats are practical.
Separately, an adhesive has been created which bonds to many surfaces. In internal evaluations of two laminated plies of woven carbon fiber and two plies of glass fabrics, both passed a 60 second vertical burn with no ply separation, distortion or flaming drips from the adhesive.
Dynamic Modifiers envisages many uses for PAL…VersaCHAR, from aerospace to the protection of rigid structural materials in building interiors etc.
