- Thermal stability Since the self-extinguishing properties of flame retardant ABS may result from the thermal decomposition of flame retardants during burning, flame retardant ABS can have poor thermal stability in comparison with general ABS. In particular, since flame retardants can possibly decompose when molded at temperature of 230oC or above, molding at lower temperatures than required with general ABS is recommened. Cheil Industries Inc. has developed the technology to produce Starex flame retardant ABS with excellent thermal stability and flame retardancy. Starex flame retardant ABS, especially VH-0853 and VH-0800, is useful for geometrically complex molds.
- Weather resistance Since ABS contains butadiene to enhance impact strength, it can be discolored if exposed to sunlight for a longtime. And this prevents its usefulness with such O.A. applicances as computer monitors, printers, and photocopying machine. As one of the leading companies in the production of ABS resin. Cheil has made the effort to solve these problems, and it has successfully produced a flame retardant ABS series with excellent weather resistance. Among the series, VH-0853, VE-0812,VE-0855 or VE- 0856 can be the best choice for applications demanding weather resistance.
- Blooming and plating-out During injection molding, flame retardants can diffuse out to the surface and cause mold contamination. Since this phenomenon becomes worse with darker colors, it is recommended not to use flame retardant ABS grade resins with dark color shades. However, blooming is not observed while using all Starex flame retardant ABS grade exceptVH-0853. Starex flame retardant ABS grades with their excellent qualities allow for flexible product designs.
- 4) Heat resistance Heat resistance implies that the product is not prone to deformation while being exposed to a wide temperature range.The excellent heat resistance of Starex flame retardant ABS makes it possible to increase the reliability of injection molded products. However care must be taken to select the proper grade of Starex flame retardant ABS for final use. For cost reduction and improved injection productivity,the VE-series can be the best choice as an engineering plastics substitute,while the VH-series is suitable when processability is more important design factor than heat resistance.
