Overview
ABS (Acrylonitrile Butadiene Styrene) is a versatile thermoplastic polymer composed of three monomers: acrylonitrile, butadiene, and styrene. It is renowned for its excellent mechanical properties, including impact resistance, rigidity, and ease of processing. ABS is widely used in industries ranging from automotive to consumer goods due to its balance of strength and affordability. The term 'ABS奇美' refers to ABS resins produced by Chi Mei Corporation, a leading manufacturer known for high-quality ABS grades. These resins are tailored for specific applications, such as injection molding, extrusion, or 3D printing, making them a preferred choice for B2B buyers.
Physical and Chemical Properties
ABS exhibits a unique combination of properties derived from its three monomers. Acrylonitrile provides chemical and thermal stability, butadiene enhances impact resistance, and styrene contributes rigidity and gloss. The material is opaque, with a density slightly higher than water, and can be easily colored or finished. ABS is resistant to many acids, alkalis, and oils but can degrade under prolonged UV exposure unless stabilized. Its melting range (105–125°C) makes it suitable for injection molding, while its low moisture absorption ensures dimensional stability during processing.
Main Applications
ABS is a workhorse material in manufacturing. In the automotive sector, it is used for dashboards, wheel covers, and interior trim due to its durability and aesthetic appeal. Consumer electronics, such as keyboard keys and phone cases, rely on ABS for its machinability and smooth surface finish. The toy industry, including LEGO bricks, extensively uses ABS for its safety and color retention. Industrial applications include pipes, fittings, and protective housings, where its impact resistance and chemical stability are critical.
Safety and Storage
ABS is generally considered safe for handling but requires precautions during high-temperature processing. Melting ABS can release styrene vapors, which may irritate the eyes and respiratory system. Adequate ventilation and personal protective equipment (PPE) are recommended. Storage should prioritize avoiding moisture absorption and UV exposure. ABS pellets should be kept in sealed containers or bags in a dry, cool environment to prevent degradation before use.
B2B Procurement Guide
When procuring ABS, B2B buyers should prioritize grade specifications tailored to their application. Key factors include impact resistance (e.g., high-impact grades for automotive parts), UV stability (for outdoor use), and flame retardancy (for electronics). Supplier reliability is critical; certifications like ISO 9001 and material datasheets should be verified. Bulk pricing typically ranges from $1.50 to $3.00 per kg, but custom formulations may cost more. MOQs (Minimum Order Quantities) and lead times vary by supplier.
