Most keyboards in the world have keycaps made of ABS. ABS is short for "Acrylonitrile Butadiene Styrene", being a copolymer of these three monomers. ABS exists in many different formulations for different applications. (Poly)styrene is the main ingredient. Butadiene makes it more flexible and less brittle. Acrylonitrile makes it harder. ABS, and other blends with Polystyrene (PS) are some of the most commonly used plastics for computer equipment, including keyboard cases.
ABS keys is the prefered plastic to double-shot molding. That is because most other plastics shrink too much in the moulding process. Legends on ABS keys can also be pad-printed, laser-etched (burned) or laser-engraved (with or without infill). Because of the low shrinkage, some keyboards have space bars made of ABS even if other keys are made of PBT or POM.
Double-shot moulding, double-shot, dual-injection moulding, two-shot moulding or insert moulding is the process of moulding plastic around a preformed metal or plastic insert. This has been a popular process to create very durable keycaps in the past. Recently, the process has become more rare
Maximum contrast lettering: the legends are bold and vibrant and pure in tone, with smooth edges and uniform colouration.
Zero wear: the legend will never wear, as it runs right through the surface of the keycap.
Colour freedom: the keycap and legend can each be of any colour desired: this lends itself well to custom keycaps where a wide range of colours is highly desirable.
Feel: the legend and the keycap are one, and the legend cannot be felt while typing
