Exolit OP
Résumer

Are you considering to switch from brominated flame retardants (with antimony trioxide) to halogen-free? Consider Exolit™ OP.

Exolit OP, based on organic phosphinate technology, is Clariant's high-performance non-halogenated flame retardant range for engineering plastics. This innovative portfolio not only provides superior flame retardancy but also maintains the mechanical properties of materials like polyamide (PA), perfect for demanding electrical and electronic applications. As a suitable alternative to brominated flame retardants (BFR) with antimony trioxide (ATO), what sets Exolit OP apart is its ability to maintain performance properties throughout the product lifecycle and after recycling. The portfolio combines excellent fire safety performance with high mechanical strength and proven recyclability, while being halogen-free. Suitable end applications are e.g. consumer electronics, electrical installations (connectors, circuit breakers), energy storage, household appliances as well as transport applications like E-mobility, trains and aviation.

  • Exolit™ OP 1400
    Exolit OP 1400 is a non-halogenated flame retardant based on organic phosphinates for reinforced polyamide 6, polyamide 66 and high temperature polyamides. The product achieves its flame retardant effect through a combined gas phase and condensed phase mode of action. Exolit OP 1400 is based on a new chemical substance which is currently being registered in various national and regional chemical inventories.For more details see our Innovation Spotlight video.

  • Exolit™ OP 1312
    Exolit OP 1312 is a non-halogenated flame retardant based on organic phosphinates. The product achieves its flame retardant effect through intumescence. The thermoplastic polymer with Exolit OP 1312 foams and crosslinks on exposure to flame and forms a stable char at the surface acting as a barrier. The protective layer provides a heat-insulating effect, reduces oxygen access and prevents dripping of molten polymer. Exolit OP 1312 is a white powder.For more details see our Innovation Spotlight video.

  • Exolit™ OP 1230
    Exolit OP 1230 is a white, fine-grained powder based on an organic phosphinate. The product is non-hygroscopic and it is insoluble in water and organic solvents. Clariant’s Exolit OP flame retardants for polyamides are all based on aluminum diethyl-phosphinate (= DEPAL). The pure substance DEPAL is sold as Exolit OP 1230 and in combination with synergists as Exolit OP 13xx types. Exolit OP 1230 is the first non-halogenated flame retardant which can withstand the demanding requirements of this high end segment of engineering plastics.For more details see our Innovation Spotlight video.
