PBT Backlit Keycaps for Cherry MX Switches UK ISO QWERTY - BlackPBT
PBT (short for "polybutylene terephthalate") is one of the hardest, most durable materials for keycaps. It is more resilient against heat and chemicals than ABS, but its properties also makes it more difficult to mould, which makes it more uncommon.
Legends on PBT keys are often laser-etched or dye-sublimated but only very rarely double shot moulded. PBT does not turn yellow from exposure to ultraviolet light, like ABS does. The resilience against heat makes it a good candidate for dyeing in a hot dye bath.
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
Double Shot Keys.
