ABS vs. PBT Keycaps: Which One Should You Choose?

Mechanical keyboard enthusiasts know that every detail matters—from switch type to the material of the keycaps themselves. While most casual users might not give a second thought to what their keys are made of, the choice between ABS (Acrylonitrile Butadiene Styrene) and PBT (Polybutylene Terephthalate) keycaps can significantly impact your typing experience, durability, and overall keyboard aesthetic.

What Are Keycaps?

Keycaps are the removable covers that sit atop the switches of a keyboard, serving both functional and aesthetic purposes. They play a crucial role in protecting the delicate switches beneath them from dust and debris while defining the tactile feel and responsiveness of the keyboard. Additionally, keycaps influence the sound produced when typing, impacting the overall auditory experience. Beyond functionality, they also contribute to the visual appeal of a keyboard, allowing users to customize their setup with different colors, fonts, and designs to match personal preferences and enhance typing comfort.

What Are ABS Keycaps?

ABS keycaps have long been the standard in the keyboard manufacturing world. Made from a lightweight and relatively inexpensive plastic, these keycaps have some distinctive characteristics that have kept them popular for decades.

Pros of ABS Keycaps

• ABS is cheaper to produce, making keyboards with these keycaps more budget-friendly.
• The material takes dye extremely well, allowing for bright, saturated color designs.
• ABS keycaps are typically lighter, which can contribute to a more nimble typing feel.

The Shine Problem

However, ABS keycaps come with a notorious drawback: shine. With prolonged use, the keycap surface becomes glossy and smooth, a process keyboard enthusiasts call "ABS shine." This occurs because the oils from your fingers gradually wear down the keycap's texture, creating a slick, less pleasant typing surface.

Why Choose PBT Keycaps for Your Keyboard?

Enter PBT keycaps—a material that has gained significant popularity among mechanical keyboard aficionados for its superior durability and texture.

Advantages of PBT

• PBT is significantly more resistant to wear, maintaining its texture and appearance even after years of use.
• These keycaps have a rougher, more substantial feel that many typists prefer.
• Unlike ABS, PBT keycaps are highly resistant to the glossy wear that plagues their counterparts.

Manufacturing Challenges

The robust nature of PBT comes with its own set of challenges. The material is harder to mold and dye, which means PBT keycaps are typically more expensive and often come in more muted or limited color schemes.

How Do ABS vs. PBT Keycaps Compare in Terms of Sound and Feel?

The material of your keycaps isn't just about looks—it significantly influences your typing experience.

ABS Keycaps

• Tend to produce a higher-pitched, more "plasticky" sound
• Smoother typing feel
• Slightly lower typing resistance

PBT Keycaps

• Generate a deeper, more satisfying typing sound
• Provide more textural feedback
• Offer a slightly more substantial typing experience

Why is the Manufacturing Process Different?

The variance in keycap performance comes down to fundamental material properties. ABS is softer and more malleable, making it easier and cheaper to produce. PBT, with its higher melting point and more complex molecular structure, requires more sophisticated manufacturing techniques.

How to Choose Your Keycaps

Choosing the right keycaps depends on your specific needs and budget. For casual users and office workers, standard ABS keycaps offer an affordable and comfortable typing experience. These keycaps work well for light to moderate typing and come with most pre-built keyboards.

Budget-conscious professionals should look for mid-range PBT keycaps or high-quality ABS sets. Watch for sales and group buys, or consider partial upgrades to key areas you use most frequently.

Gamers will benefit most from PBT keycaps with gaming-specific designs, which offer superior durability and better grip and often come with aesthetic options that complement gaming setups. Look for sets that highlight crucial gaming keys like WASD.

Mechanical keyboard enthusiasts and professionals who type for long hours should invest in premium double-shot PBT keycaps. These provide excellent texture, minimal shine, and long-lasting performance. Consider sets with ergonomic profiles or unique designs that match your specific needs.

The ultimate advice is simple: match your keycaps to your usage. Consider your typing style, budget, and primary keyboard use. Don't be afraid to start small and upgrade gradually as you understand your preferences.

How to Care for Your Keycaps

Maintenance Tips

ABS Keycap Care

• Clean regularly with a microfiber cloth to slow down the shine
• Avoid direct sunlight, which can accelerate material degradation
• Consider using a keyboard cover when not in use

PBT Keycap Maintenance

• Use compressed air to remove dust and debris
• Occasionally wash with mild soap and lukewarm water (ensure completely dry before reinstalling)
• Store in a cool, dry place away from direct heat

Upgrade Strategies

• Can't afford a full PBT set? Replace most-used keys first (spacebar, WASD for gamers, home row for typists)
• Look for group buys or wait for sales on premium keycap sets
• Learn basic keycap removal and replacement to save on professional services

When to Replace

Replace keycaps if you notice:

• Significant shine on ABS sets
• Wear that affects typing comfort
• Desire for a different aesthetic or typing feel
