Solving burning problems
PLASTICS IN E&E PRODUCTS HAVE TO BE
PROTECTED FROM FIRE

Plastic components connected to electrically live metal parts tend to burn easily and must comply with strict fire safety regulations. Therefore electronic devices have to be protected by flame retardants, which prevent or delay the development and spread of fires in various ways. With Exolit® OP Clariant offers a product family of tailor-made flame retardants based on non-halogenated organic phosphorus compounds which are a safe and environmentally compatible alternative to traditional ones. We’ve been developing and advancing this technology for over two decades. This effort resulted in more than 500 patents or patent applications globally.
 

Challenge
HELPERS FOR BURNING PROBLEMS CAN
SOMETIMES BE DANGEROUS THEMSELVES
So-called halogenated flame retardants are under debate: during a fire, corrosive smoke gases can be released. Decomposition products such as halogenated dioxins can be produced and some halogenated flame retardants themselves are suspected of being hazardous to health.

Solution
EXOLIT® OP PRODUCT FAMILY QUENCHES FIRE BEFORE IT STARTS
The latest Exolit® OP series is based on non-halogenated organic phosphorus compounds. Extensive toxicological tests along their life cycle in plastic have demonstrated their favourable environmental profile. When plastic containing Exolit® OP burns, it releases gases that cause burning plastic to foam and rapidly form a protective layer of foamed char which itself is no longer combustible. This protective layer both isolates the underlying plastic that has not yet burned against heat, and at the same time keeps out the atmospheric oxygen.

  • 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.

  • Exolit® OP 1260

    Flame Retardant for Polyester Exolit OP 1260 is a non-halogenated flame retardant based on organic phosphinates. The product achieves its flame retardant effect through a combined gas phase and condensed phase mode of action. Exolit OP 1260 is based on commercially available chemical substances registered in inventories worldwide.For more details see our Innovation Spotlight video.

  • Exolit® OP 1311

    Exolit OP 1311 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 1311 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 1311 is a white powder.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 1314

    Exolit OP 1314 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 1314 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. Compared to Exolit OP 1312, the product gives an improved thermal stability of polyamide compounds. Exolit OP 1314 is a white powder.For more details see our Innovation Spotlight video.
