Are you wondering whether to choose ABS or PBT keycaps for your keyboard? This guide will break down the main differences in durability, texture, and cost to help you decide which best suits your needs.

Understanding ABS Keycaps

ABS keycaps are made from acrylonitrile butadiene styrene (ABS), a thermoplastic polymer known for its durability and flexibility. This combination of properties makes ABS keycaps popular for many keyboard manufacturers. The acrylonitrile component provides chemical resistance and thermal stability, while butadiene enhances toughness and impact resistance, contributing to the overall flexibility of the keycaps.

Some of the standout features of ABS keycaps include:

• Smooth texture

• Wide variety of vibrant color options

• Lightweight design, which can enhance the overall typing experience by reducing finger fatigue during extended use

• It can be manufactured in various intricate shapes thanks to the flexibility offered by the injection molding process

ABS keycaps come in different designs, including single-shot and double-shot styles. Single-shot keycaps are made from one layer of plastic, while double-shot keycaps are made from two layers, ensuring that the legends remain vibrant and do not fade over time.

Advantages of ABS Keycaps

One of the most significant advantages of ABS keycaps is their affordability. The simpler manufacturing process makes ABS keycaps cheaper to produce, which is why they’re commonly found on many keyboards. Despite their low cost, ABS keycaps offer a smooth and somewhat glossy texture that many users find appealing.

Other notable benefits of ABS keycaps include:

• Impact resistance, making them less prone to breaking under stress.

• High clarity and sharpness in colors and lettering, enhancing visibility and aesthetics.

• Clear illumination, making them ideal for backlit keyboards where visibility in low-light conditions is crucial.

Disadvantages of ABS Keycaps

While ABS keycaps have many advantages, they also have some drawbacks. One of the most common complaints is that they tend to become shiny and slick over time due to wear, making them less comfortable to type on than when they were new.

Another significant disadvantage is their relatively short lifespan. ABS keycaps wear out more quickly than other materials, which can lead to the inscriptions wearing off completely, affecting overall usability.

Understanding PBT Keycaps

PBT keycaps are made from polybutylene terephthalate (PBT), a material renowned for:

• Durability and resistance to shine

• Maintaining a matte finish that prevents glare and enhances the typing experience (unlike ABS)

• Rigidity and durability

• Excellent chemical resistance

These qualities make PBT a high-quality choice for keycaps.

PBT keycaps are often found on high-end keyboards, reflecting their premium status in keycap materials. The material has a high melting point of 223°C (433°F), which means it can withstand significant heat without deforming.

In terms of texture, PBT keycaps offer a grainy or smooth feel that many users find pleasant to type on, enhancing grip and contributing to a more satisfying typing experience. Compared to ABS keycaps, PBT keycaps tend to retain their original texture and appearance for a longer time.

Advantages of PBT Keycaps

One of the most significant advantages of PBT keycaps is their increased durability. They are more resistant to UV light, which helps them maintain their color over time, unlike ABS keycaps that can fade.

PBT keycaps also typically feature a matte finish, which reduces glare and offers a more premium aesthetic. The textured surface of PBT keycaps enhances the typing experience, providing a more tactile and satisfying feel compared to the smoother ABS keycaps. These qualities make PBT keycaps a favorite among keyboard enthusiasts who prioritize durability and a premium typing experience.

Disadvantages of PBT Keycaps

Despite their many benefits, PBT keycaps do have some drawbacks. They can be nearly twice the price of ABS keycaps, making them a far more expensive option. This is due to the need for specialized materials and more complex manufacturing processes. For budget-conscious users, the price difference can be a significant consideration.

Additionally, PBT keycaps tend to have limited options for vibrant colors and intricate designs. Fewer manufacturers produce PBT keycaps because of the expensive materials and processes involved.

Comparing ABS and PBT Keycaps

When comparing ABS and PBT keycaps, several factors come into play, including:

• Texture and feel

• Sound profile

• Cost and value

• Availability and design options

These aspects can significantly impact your typing experience and overall satisfaction with your keyboard.

While PBT keycaps generally offer superior texture and sound characteristics, ABS keycaps are often more affordable and available in a broader range of designs. The choice between ABS and PBT ultimately comes down to personal preference and what you prioritize in a keycap set.

Texture and Feel

The texture and feel of keycaps are crucial for a satisfying typing experience. PBT keycaps offer a more tactile experience due to their grainy surface, which maintains a matte finish that enhances grip.

In contrast, ABS keycaps become glossy and slick over time, losing their original texture. While they start with a smooth feel, the wear-resistant properties of PBT make them a more durable choice for those who type frequently.

Sound Profile

The sound profile of keycaps can significantly affect the typing experience. PBT keycaps often produce a richer, more muted sound compared to the louder, clickier sound of ABS keycaps.

On the other hand, ABS keycaps generate a louder and clickier sound, which may appeal to users who enjoy pronounced audio feedback while typing. The sound produced by keycaps is generally a significant consideration for typists, affecting their overall satisfaction with their keyboard.

Cost and Value

When it comes to cost and value, ABS keycaps are generally more affordable than PBT keycaps. However, the mechanical keyboard community often views the higher price of PBT keycaps as justified due to their durability and longevity.

While ABS keycaps offer a cheap, low-cost option, the long-term value of PBT keycaps can make them a worthwhile investment.

Availability and Design Options

ABS keycaps are widely available in various designs and profiles, making them a versatile choice for many users. The manufacturing process for ABS keycaps allows for a wide range of vibrant colors and intricate designs, appealing to those who prioritize aesthetics.

In contrast, PBT keycaps are less common due to manufacturing challenges and higher production costs. Fewer high-quality double-shot PBT keycap options are available, and they often come with a more limited selection of colors and designs, despite their high demand.

However, dye sublimation PBT keycaps allow for intricate and vibrant designs, making them a popular choice among enthusiasts seeking aesthetic customization.

Special Types of Keycaps

Special types of keycaps, such as double-shot and pudding keycaps, offer unique features and benefits. Double-shot keycaps are made from two layers of plastic, ensuring that the legends remain vibrant and do not fade easily.

Pudding keycaps are double-shot keycaps designed with a translucent outer layer that allows RGB lighting to shine through, creating a unique optical effect. These keycaps are available at various prices, making them accessible to many users who want to enhance their backlit keyboards.

How to Upgrade Your Keycaps

Upgrading your keycaps can be a straightforward process if you have the right tools and follow some simple steps. To start, you’ll need a keycap puller, which can be a wire or ring type, to easily remove the existing caps. If you don’t have a keycap puller, you can create a DIY version using a paper clip bent into a ‘J’ shape.

Before you begin, it’s a good idea to photograph your keyboard layout to ensure you reinstall the keycaps correctly. When installing new keycaps, start with the larger keys needed to provide ample space for handling the smaller ones.

Compatibility with the keyboard switches stems is crucial, as mismatched stems can hinder the fitting of new keycaps. If you experience resistance while installing a keycap, it may indicate misalignment or incompatibility with the keyboard.
