ABS sheet is an emerging material in the sheet industry. Its full name is Acrylonitrile / Butadiene / Styrene Copolymer Sheet, commonly known as ABS (Acrylonitrile-butadiene-styrene). It is currently one of the most widely produced and widely used polymers. ABS combines the properties of PS, SAN, and BS, offering a well-balanced combination of toughness, hardness, and rigidity with excellent overall mechanical performance.

What Are the Characteristics of ABS Sheets?
Excellent Mechanical Properties ABS sheets have outstanding impact strength and can be used even at very low temperatures. They offer good wear resistance, excellent dimensional stability, and oil resistance, making them suitable for bearings under medium load and speed. ABS has better creep resistance than PSF and PC, but lower than PA and POM. Its bending and compressive strength are relatively lower among plastics. The mechanical properties of ABS are significantly affected by temperature.
Chemical Resistance ABS is resistant to water, inorganic salts, alkalis, and many acids. However, it is soluble in ketones, aldehydes, and chlorinated hydrocarbons. Exposure to glacial acetic acid, vegetable oils, and similar substances may cause stress cracking. ABS has poor weather resistance and degrades easily under ultraviolet light; after about six months of outdoor exposure, its impact strength can be reduced by half.
Processing and Performance Advantages ABS sheets feature excellent impact resistance, good dimensional stability, easy coloring, and excellent molding and machining performance. They offer high mechanical strength, high rigidity, low water absorption, good corrosion resistance, easy bonding, and are non-toxic and odorless. ABS also has good chemical resistance and electrical insulation properties. It resists heat deformation and maintains high impact toughness even at low temperatures. ABS is hard, scratch-resistant, and not easily deformed, with low water absorption and high dimensional stability. Standard ABS sheets are not very white, but they have excellent toughness. They can be cut with a shearing machine or processed by mold punching.
Thermal Performance The heat deflection temperature of ABS sheets ranges from 93–118°C, and this can be increased by about 10°C after annealing. ABS maintains a certain level of toughness even at -40°C and can be used within a temperature range of -40°C to 100°C. Transparent ABS sheets offer excellent clarity and polishing performance, making them an ideal alternative to PC sheets. Compared with acrylic, ABS has much better toughness and can meet the requirements for fine and detailed machining.
