BX FR OP1312


BX FR OP1312 is a halogen-free flame retardant based on organic phosphinates. The product achieves its flame retardant effect through intumescence. The thermoplastic
polymer with BX FR OP1312 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 insulation
effect, reduces oxygen access and prevents dripping of molten polymer.


BX FR OP1312 is white powder, developed especially for Nylon. It is suitable for both glass fiber reinforced Nylon and non-reinforced Nylon. The flame retardant Nylon
exhibits excellent physical and electrical properties.

In glass fiber reinforced Nylon 6 or 6.6, recommended to add 13 to 16% (by weight). BX FR OP1312 is usually sufficient to achieve the UL94 V-0 flame retardant requirements (at 1.6
0.8mm thickness).Due to different formulations and processing conditions, the dosage of flame retardant may be different.
