It is developed for glass fibre reinforced PBT and polyester injection molding applications. It achieves its flame retardant effect through a combined gas phase and condensed phase mode of action. Exhibits recyclability as well as very good physical and excellent electrical properties. Designed for connectors, switches, enclosures, housings, engine covers, small structural parts, cables, electrical parts. It is also used in seat frames for transportation, automotive, train, aircraft and ships. Exolit® OP 1260 (TP) is recommended at a dosage rate of 18-20 %wt to obtain the UL 94 V-0 classification for electrical components. Exolit® OP 1314 by Clariant is a halogen-free, intumescent, organic phosphinate. Acts as a flame retardant. Exhibits higher thermal stability, good colorability and good processability. Designed for glass fiber reinforced and unreinforced PA6 and PA66. Possesses very good physical and electrical properties. Offers a heat-insulating effect, reduces oxygen access and prevents dripping of the molten polymer. Exolit® OP 1314 provides good contrast in laser marking and low material density. It has a shelf life of 12 months. Exolit® AP 422 A by Clariant is a fine-particle, non-halogenated ammonium polyphosphate flame retardant with less than 0.1% melamine. It is a favorable environmental and health profile colorless, non-hygroscopic, biodegradable, non-flammable grade free of SVHCs. It is effective in cellulose-containing materials such as paper and wood products, and polyolefin-based wood plastic composites (WPC) with high wood contents (>50%).<br>
<ul style="padding-left: 40px;"><li>It has extremely low vapor pressure, water solubility, acid number and viscosity in aqueous suspensions.</li>
<li>It is suitable for various PUR applications including flexible polyester-based PUR foams, with minimum impact on reaction profiles and material properties.</li>
<li>It is an essential component in intumescent formulations for thermoplastics, particularly polypropylene, for which the classification UL 94-V0 is specified for applications in the electrical sector.</li>
