1. ABS is hygroscopic; if left exposed to the air for extended periods, it readily absorbs moisture, which can lead to the formation of bubbles or silver streaks during injection molding. Therefore, storage areas must be kept dry.
2. ABS resins of different grades or functional specifications should not be mixed indiscriminately. Mixing general-purpose, flame-retardant, and glass-fiber-reinforced grades can result in issues such as color inconsistency, cracking in finished products, and failure to meet performance standards.
3. ABS pellets undergo slow oxidation and yellowing during prolonged storage. Companies should regularly inventory slow-moving stock, accelerate raw material turnover, and minimize material depreciation.
4. Temperature control during production is critical. ABS has limited heat resistance; processing at excessively high temperatures for extended periods can cause material degradation, directly compromising the quality of the finished product.
5. Regrind-including sprues, runners, and purged material-must be stored separately by type. Natural, colored, and flame-retardant materials should be sorted individually, as the recycling value varies significantly across these categories.
