[Chemical Knowledge]：Interpretation of PBT: the world's most popular mechanical keyboard key cap material

Read： 736 Time：17months ago Source：Transform the World with Simplicity

PBT(Polybutylene Terephthalate) is a plastic material made of polyester. It is a high-quality, high-durability keycap material, often used in mechanical keyboards, especially for high-end mechanical keyboards. In contrast, ABS(Acrylonitrile Butadiene Styrene), a common keycap material, is made from styrene, butadiene, and acrylonitrile. The advantages of

PBT keycaps

1. Higher durability: PBT keycaps have higher durability than ABS keycaps, and can withstand more use and friction without wear and fading.

2. More intense color: PBT keycaps are saturated in color and usually stay beautiful for a long time without fading or darkening.

3. feel more comfortable: PBT keycap compared to other keycaps, more hard, so the hand feels more calm.

4. better gloss resistance: PBT key cap texture and texture compared to ABS texture to be more rough, will not appear excessive reflection luster.

5. good thermal stability: PBT material stability in high temperature environment is very good, making the mechanical keyboard even after long-term use, still will not deteriorate or even melt.

the disadvantages of PBT keycap

1. higher cost: compared to other materials, the cost of PBT keycap is higher, mainly because the use of PBT material level is higher.

2 is more difficult to manufacture: PBT material is relatively hard and requires high pressure manufacturing, so it is more difficult to manufacture keycaps than using ABS. How do

choose PBT keycaps?

1. Consider color: PBT keycaps are rich in color, you can choose the color according to your preferences, and PBT keycaps often do not fade or darken.

2. Consider the pattern: PBT keycaps are not only monochrome, there are a variety of patterns, some keycaps and even carving and other processes, can increase the beauty and atmosphere of the chopping board.

3. Consider accessories: Compatibility and matching between keycap diameter, height, and accessory size is still very important.
PBT keycaps in the field of
mechanical keyboards not only have excellent quality performance, but also play a very important role in keyboard operation experience, but also constantly develop and improve, providing more e-sports enthusiasts and keyboard players with better keyboard experience, and becoming the choice of more and more players.
