September 14, 2024 – As the booming electric vehicle industry and the constant upgrading of household appliances and gas equipment bring electricity and fire applications into our daily lives more prominently, they usher in unprecedented convenience. However, these technological advancements also carry potential safety hazards, making the flame retardancy of materials a crucial factor. Amid various flame-retardant materials, flame-retardant PC/ABS alloys and flame-retardant ABS materials stand out due to their exceptional overall performance, earning them favor among injection molding factories. So, what sets these two materials apart?
Firstly, in terms of flame retardancy, both flame-retardant PC/ABS and flame-retardant ABS can meet high flame retardancy requirements, such as V0 and 5VA levels. Notably, flame-retardant PC/ABS primarily adopts a halogen-free flame retardant system, which is not only halogen-free but also generates relatively less odor during the injection molding process, making it more environmentally friendly. In contrast, flame-retardant ABS mostly employs a brominated flame retardant system, offering a more pronounced flame retardant effect.
Regarding processing, significant differences exist between flame-retardant PC/ABS and flame-retardant ABS. According to Color Masterbatch Industry News, flame-retardant PC/ABS produces less odor during processing and does not corrode molds, but it requires higher processing temperatures and is relatively more challenging to mold. On the other hand, while flame-retardant ABS has a lower processing temperature and is easier to mold, prolonged processing may lead to mold corrosion, and it generates a stronger odor during the process.
Moreover, the two materials exhibit distinct differences in physical properties. Flame-retardant PC/ABS outperforms flame-retardant ABS in tensile strength, flexural strength, and impact resistance. Specifically, the notched impact strength of flame-retardant ABS generally hovers around 20KJ/m², whereas flame-retardant PC/ABS can reach over 45KJ/m², demonstrating stronger impact resistance.
In summary, while flame-retardant PC/ABS alloys and flame-retardant ABS each have their pros and cons, both are highly sought-after flame-retardant materials in the market. When making selections, injection molding factories should consider their specific needs and product performance requirements, taking into account various factors to choose the most suitable flame-retardant material.
