What is ABS plastics? |
ABS machinable plastic is a tough, rigid thermoplastic material with high impact strength. It is easily machined and ideal for turning, drilling, milling, sawing, die-cutting and shearing. ABS plastics provide a balanced combination of mechanical toughness, wide temperature range, good dimensional stability, chemical resistance, electrical insulating properties, and ease of fabrication. ABS is heat resistant and impact resistant even at low temperatures and has high chemical and abrasion-resistance as well as a good dimensional stability. ABS plastics are easily machined and die cut in thinner gauges. ABS can be cut with standard hand held power tools and line bent with our standard heat strips. ABS can be adhered to itself and other like plastics using weld-on adhesives.
• Easily machinable and fabricated • Tough and rigid |
ABS Applications |
ABS plastics are used in thermoforming applications where heat-induced flexibility and physical appearance are preferred. A high-impact resistance in combination with a hardcell-textured surface also makes ABS plastics ideal for consumers who are looking for an attractive faceplate. ABS plastics come in both machine and extruded grades:

Physical Properties of ABS Sheet |
|
ABS has desirable impact strength at room temperature and, in special grades, at temperatures as low as -40°F (-40°C). ABS works for some outdoor use. Overexposure to the sun may cause color deformation and decrease the durability and overall appearance of the product; in such cases, a UV protective grade is better suited. |
