ABS (Acrylonitrile Butadiene Styrene) is one of the most widely used polymers in injection molding. The styrene content gives it a shiny, impervious surface, and the polybutadiene provides excellent toughness, even at low temperatures. The chemical structure of ABS also allows it to be modified to improve certain characteristics depending on the application at hand. At Proto-Cast, we know the value and versatility of ABS injection molding.
Characteristics of ABS Injection Molding Plastic
ABS is a low-cost, durable plastic that is easy to machine and fabricate. There are many different grades of ABS plastic available, including high-impact, glass-filled, transparent, and high luster formulations. It has good resistance to scratching and can be made in a wide range of colors. ABS plastics have good electrical properties that are fairly constant over a wide range of frequencies. They also work well when paired with metal coatings because the coating is able to adhere strongly to ABS plastic.
The properties of ABS injection molding plastic aren’t greatly affected by temperature and humidity in the acceptable operating range of temperatures. Its final properties can be influenced by the conditions under which it is processed. For example, molding at low temperature creates the highest strength and impact resistance, while molding at high temperatures improves heat resistance and gloss.
ABS injection molding plastic is ideal for structural applications that require impact resistance, strength and stiffness. It has excellent dimensional stability and is easy to paint and glue, making it the common choice to machine pre-production prototypes. As a thermoplastic, ABS plastic can also be easily recycled.
