Dynamic modifiers have launched a new non-halogenated flame retardant (FR) compound called PAL...VersaCHAR. The compound can achieve a new level of flame retardant performance as a coating for nonwovens and technical textiles. Dynamic modifiers are a leading specialty compounder focused on custom polyolefin compounds and concentrates. PAL...VersaCHAR has been tested to 1,950 □C, the highest 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 behaviour protects any underlying substrate to which it is adhered, according to dynamic modifiers.The compound has passed ASTM e84 (class a) with a 15/10 rating, which includes 'clean' smoke generation of only 2.3 per cent of the allowable ASTM smoke limits. In addition, the compound is light weight, at a specific gravity of 1.0, and 100 per cent 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 ultraviolet or antimicrobial performance, as volume warrants. In addition to its use as a coating, PAL..VersaCHAR compound can be produced as a flexible film or sheet and moulded to shape or over-moulded to most materials, including metal for corrosion resistance as a polymeric compound it can be cast or calendered and typical durometres from 80-99a for flexible-to-high rigid formats are practical. Separately, an adhesive has been created which binds to many surfaces. In internal evaluations of two laminated plies of woven carbon fibre 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 and so on.
