Keycap Materials for Mechanical Keyboards
Mechanical Keyboards have become so popular among users owing to their robustness, customization possibilities, and enhanced typing experiences. A vital part of the customization is the keycaps, which adds a touch of style while offering smooth typing. The array of materials used for keycaps significantly determines the user’s tactile experience, the aesthetic appeal, sound, and longevity of the mechanical keyboards. The major types of keycap materials include ABS, PBT, POM, and PVC. These materials have their unique strengths as well as downsides. This article elaborates on different keycap materials, aiming to guide you in selecting the best keycap for your mechanical keyboard.
1. ABS (Acrylonitrile Butadiene Styrene)
ABS is a widely used plastic for keycaps because it’s easy to mold, possessing properties that contribute to a soft, flexible, and smooth texture. ABS material can seamlessly support double-shot injection molding, a process where two plastic elements are melded together. This enables the creation of keycaps with dual colors in a discreet piece, with characters that won’t fade even after prolonged use.
However, if longevity is a priority, ABS may not be your best bet. They are prone to “shine” over time due to finger oils which makes the keys look glossy and feel slippery to the touch. But with ABS, you’ll enjoy vibrant color options and outstanding customization choices due to the ease of printing on this material.
2. PBT (Polybutylene Terephthalate)
PBT stands as a viable alternative to ABS. PBT keycaps don’t suffer from “shine” as quickly as their ABS counterparts. This material tends to be stiffer, rougher, and more durable, well-known for its resistance to chemical and heat exposures. PBT material shrinks more while cooling, leading to warped keycaps occasionally. PBT is ideal for dye sublimation or laser marking but not as compatible with double-shot molding as ABS due to its heat resistance characteristics.
Nonetheless, PBT is a go-to choice for enthusiasts who prioritize long-lasting, sturdy keycaps. The slightly grainy texture of PBT keycaps helps combat slippage from sweaty fingers, providing a continuously comfortable typing experience.
3. POM (Polyoxymethylene)
POM, also known as Delrin, Acetal, or Polyacetal, offers properties that sit right between ABS and PBT. While retaining the smoothness of ABS, the POM is much sturdier and exhibits a unique ‘dry’ sensation. Moreover, POM is resistant to wear and tear, heat, water, and substances such as solvents and detergents.
POM keycaps possess an impressive self-lubricating feature, which offers a unique silky feel while typing. However, there’s a knack to producing POM keycaps as they can’t easily be dyed or printed on, hence they’re often seen in their natural white, black, or other neutral hues.
4. PVC (Polyvinyl Chloride)
PVC is another material found in keycaps, mostly for translucent or backlight-compatible ones due to its excellent light transmission. PVC keycaps are soft, smooth, yet durable. However, they’re not as common as the ABS and PBT keycaps. PVC is a quite affordable choice, making it a great alternative for gamers who want backlit keys.
Each material discussed offers different advantages. ABS has smoothness and brilliant double-shot color options. PBT boasts sturdiness, a grip-friendly texture, and resistance to “shine”. POM provides a unique silky feel and excellent durability, whereas PVC is best for backlighting effects.
Understanding the unique characteristics of these keycap materials helps you make an informed decision tailored to your specific needs. Whether it be for gaming sessions, day-to-day office work, or long typing tasks, the right keycap can significantly improve your keyboard experience.
