1. What Exactly Is ABS Plastic?

ABS (Acrylonitrile Butadiene Styrene) plastic is a thermoplastic polymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. This creates a strong, rigid material resistant to impact, heat, and chemicals. The combination of these three monomers gives ABS its unique balance of properties. Acrylonitrile contributes chemical and heat resistance, butadiene provides toughness and impact resistance, and styrene contributes rigidity and processability. ABS is commonly used in injection molding applications due to its low production cost and ease of machining. According to a study by the University of Michigan, ABS plastic is one of the most versatile polymers due to its ability to be easily modified to improve impact resistance, toughness, and heat resistance.
