Introduction
The product is mainly applied to halogen-free flame retardant modification of PC, PC/ABS, PPO, LCP, PS and PA6. The flame retardant effect is good, the carbonization degree of the resin burning surface is low, and FCA-117 fluid is added, and the surface is smooth after burning.
Features
Increase the flame retardancy and reduce the heat release rate
Reduce the harmful gas CO to reduce smoke and smoke release
Improve impact strength to prevent dropping
Advantage
Improve the flame retardancy of plastics
Improve the surface performance and improve the wear resistance
Improving the mechanical properties of organic filled plastics
Application
FCA-117/KSS (potassium phenylsulphonyl benzene sulfonate) to provide PC with UL94 V-0 at 1.6mm PC transparent thin flame retardant; FCA-117/TPP (phosphoric acid three phenyl ester) to give PC/ABS UL94 V-0 with higher impact strength than TPP only PC/ABS flame retardant and high impact strength; flame retardant PS can reduce the amount of brominated flame retardants
Processing
In a twin screw extruder, the optimum result is obtained by mixing the specific screw block sequence and mixing the barrel and the screw speed. Because the viscosity of FCA-117 fluid is high and sticky, it is very difficult to prepare permanent and freely flowing FCA-117 liquid, and the premixed material of plastic resin and other dry ingredients is very difficult. The simplest way is to add FCA-117 to the extruder and mix the dry material upstream. When the resin melted, the viscosity of the mixture is uniform, then the FCA-117 liquid will be added downstream. The efficiency of the organosilicon flame retardant depends on the whole mixing process. The flame retardancy of the flame retardant resin reached the maximum, and the design of the extruder, the design of the screw and the melting temperature were applied in the twin screw extruder. In the process of extrusion, the processing of thermometer will also affect the quality and performance of the product. Process treatment strives to optimize the efficiency of flame retardancy.
Packaging and storage
This product is 200kg drum, special packaging specifications according to user requirements set. FCA-117 is a non dangerous product. In the process of storage and transportation, we should pay attention to moisture-proof and prevent impurities such as acid and alkali. The product has a shelf life of 24 months from the date of production at the condition of sealing and 25 C.
