In the world of mechanical keyboards, the quality of keycaps directly affects the typing feel and overall user experience. PBT keycaps are preferred by many keyboard enthusiasts due to their durability and pleasant texture. However, the quality of PBT keycaps available on the market varies significantly. So how can we distinguish between high-quality and low-quality PBT keycaps? This article provides a detailed guide to help you make an informed choice when purchasing.

1. Material Quality

Compared to ABS keycaps, PBT keycaps have better durability and resistance to oil. High-quality PBT keycaps are usually made from a high proportion of PBT material, giving them a dry and slightly rough texture. On the other hand, low-quality PBT keycaps may contain mixed plastics, making them smoother and more prone to developing an oily shine.

2. Keycap Thickness

Keycap thickness greatly affects the typing feel. High-quality PBT keycaps are typically thicker (around 1.5mm) and maintain consistent thickness, providing a solid keypress experience. You can check the thickness of the keycap by shining light through it—thicker keycaps are less translucent and produce a deeper sound when pressed. In contrast, low-quality keycaps are thinner, resulting in a lighter sound and a less solid feel.

3. Font and Printing

The characters on keycaps affect not only the appearance but also durability. High-quality PBT keycaps often use double-shot molding technology, where the characters are molded with different colored plastic, ensuring they do not fade or wear out over time. Low-quality keycaps may use laser engraving or ink printing, which results in blurry edges and a tendency to fade.

Characters made with double-shot molding are clear and smooth, retaining their quality regardless of usage conditions, which is particularly important for long-term users.

4. Craftsmanship and Details

High-quality PBT keycaps pay great attention to mold precision and detail processing. The edges of the keycaps should be smooth without burrs, and the mold cuts should be precise, with no excess plastic. In contrast, low-quality keycaps often have noticeable defects or inconsistencies at the bottom or edges, affecting both appearance and typing feel.

5. Sound and Feel

The sound and feel of PBT keycaps are important points of interest for many users. High-quality PBT keycaps, due to their thickness, produce a deeper and softer sound when pressed. Low-quality keycaps, on the other hand, sound higher-pitched and feel flimsy. In terms of feel, high-quality keycaps provide a consistent typing experience across the keyboard, without any uneven heights or instability during pressing.

6. Color and Oil Resistance

Color longevity is also an important criterion for judging the quality of PBT keycaps. High-quality PBT keycaps have vibrant colors that do not fade easily even after prolonged use. Low-quality keycaps may use low-cost dyes, which can fade gradually with regular use or cleaning. Additionally, high-quality PBT keycaps have excellent oil resistance, making them less likely to develop a glossy shine over time, thus maintaining a fresh look.

7. Smell Test

Sometimes, a simple smell test can also help judge the quality of keycaps. Low-quality PBT keycaps, due to the use of inferior materials, may emit a noticeable plastic odor. In contrast, high-quality PBT keycaps usually have no distinct odor, which is also an indication of good material quality.

How to Choose the Right PBT Keycaps for You

By understanding these details, you can make a more informed choice when selecting PBT keycaps. It is recommended to choose keycaps from reliable brands, especially those that provide detailed product information. User reviews and actual usage feedback are also very helpful references.

Tips

Check the material description and thickness of the keycaps before purchasing.

Prioritize PBT keycaps made with double-shot molding technology.

Choose brands with good user reviews to ensure the quality and feel of the keycaps.

Conclusion

PBT keycaps are a popular choice among mechanical keyboard users due to their excellent texture, durability, and oil resistance. However, there are various products of differing quality on the market. By understanding the key points mentioned above, you can distinguish between high-quality and low-quality PBT keycaps and enjoy a more comfortable keyboard experience. We hope this guide helps you find the perfect keycaps for your needs!
