The polyphosphonates are permanent and halogen-free flame retardant solutions. Several Nofia® types fall into this group. The areas of application are mainly in thermosets and thermoplastics. The products of the Nofia® types have an excellent fire protection effect and are not migrating. Therefore, these products are also called permanent flame retardant.

Currently there are four Nofia® series (HM Series, CO series, OL-series and W-series) are available which are polycarbonates and generally successfully used in polyurethane, epoxy resin, unsaturated polyester systems, as well as EVA adhesives. These polyphosphonates are high molecular weight products that are used both as a single additive or combined as a so-called blend. The products work in the gas phase and are characterized by low heat emission and a very low smoke density.

Typical doses are depending on the application field between 2-50 percent. The main areas of application are housings (electronics and entertainment) and products in the transport and construction sectors.
