Dynamic Modifiers: new coating with high flame retardancy

A new non-halogenated FR compound is being introduced by Dynamic Modifiers LLC, Atlanta, GA/USA, a specialty compounder for custom polyolefin compounds and concentrates. Named PAL VersaChar, it can achieve a high level of flame retardant performance as a coating for nonwovens and technical textiles.
PAL VersaChar has been tested to 1,950°C and is 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 and 100% non-toxic, being free from heavy metals, halogens and VOCs. Other properties include very good cold crack performance, hydrophobicity, printability, high chemical resistance and the ability to be custom tailored for specific needs such as UV or antimicrobial performance as required. It has passed ASTM E84 (Class A) with a 15/10 rating, which includes ‘clean’ smoke generation of only 2.3% of the allowable ASTM smoke limits.
In addition to its use as a coating, the 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.
A separate adhesive has also been created which bonds to many surfaces.
