When building or upgrading a mechanical keyboard, few choices impact your daily typing experience as much as the keycaps. The material of your keycaps determines not only how they feel under your fingers but also how long they last, how they sound, and even how they look over time. Whether you're a gamer, a writer, or a customization enthusiast, understanding the differences between ABS keycaps, PBT keycaps, and double-shot PBT keycaps is essential. In this guide, we'll break down the pros and cons of each material, explore durability and feel, and help you choose the perfect set for your setup—and we'll show you how to pair them with popular Keychron models like the Keychron Q60 Max QMK/VIA Wireless Custom Mechanical Keyboard or the Keychron Q7 QMK Custom Mechanical Keyboard.

Why Keycap Material Matters

Keycaps are the interface between you and your keyboard. They influence typing comfort, noise level, and even the longevity of the legends (the letters and symbols printed on them). While switch choice often gets the spotlight, keycap material is equally critical for a satisfying typing experience. The three most common materials are ABS (Acrylonitrile Butadiene Styrene), PBT (Polybutylene Terephthalate), and double-shot PBT—a manufacturing process that enhances durability. Let's dive into each.

ABS Keycaps: The Classic Standard

ABS has been the go-to keycap material for decades, used in everything from vintage IBM keyboards to modern gaming peripherals. It's a lightweight, cost-effective plastic that's easy to mold into intricate shapes and thin walls. Many OEM keycaps, including those found on stock keyboards, are made of ABS. The material offers a smooth, slightly glossy feel that many typists enjoy. However, ABS has a notorious weakness: it develops a shiny, greasy appearance over time due to oil absorption from your fingertips—a phenomenon known as "shining." This doesn't affect functionality but can detract from aesthetics. Additionally, legends on ABS keycaps are often laser-etched or pad-printed, which can wear off with heavy use.

Pros of ABS Keycaps

• Low cost, making them accessible for budget builds
• Wide variety of colors and profiles available
• Softer feel that some typists prefer for long sessions
• Thinner walls can produce a higher-pitched, clacky sound

Cons of ABS Keycaps

• Prone to shine and oil buildup over weeks or months
• Legends may fade or wear off with regular use
• Less durable overall compared to PBT
• Can feel slippery when hands are sweaty

ABS is still a solid choice for those on a tight budget or who plan to swap keycaps frequently. But for a long-term investment in keycap durability, many enthusiasts look elsewhere.

PBT Keycaps: The Durable Upgrade

PBT is a tougher, more resilient plastic that resists heat, chemicals, and physical wear. It's heavier than ABS, giving keycaps a denser feel and a deeper, more muted sound. PBT keycaps are highly resistant to shining—even after years of use, they retain their matte texture. This makes them ideal for daily drivers where consistency matters. The trade-off is that PBT is harder to mold, limiting design complexity and often resulting in thicker walls. This can make keycaps feel more solid but also slightly more rigid. PBT keycaps usually come with dye-sublimated legends, where the ink is absorbed into the plastic, making them virtually immune to fading. For example, the OEM Dye-Sub PBT Full Set Keycap Set - Pixel Universe offers a vibrant, long-lasting design that won't wear off.

Pros of PBT Keycaps

• Extremely resistant to shine and oil buildup
• Legends are highly durable, often lasting the lifetime of the keycap
• Heavier weight provides a more substantial typing feel
• Better sound dampening, producing a deeper tone

Cons of PBT Keycaps

• Higher cost than ABS
• Limited profile and color options due to molding challenges
• Can feel too rough or textured for some users
• Thicker walls may interfere with some switch housings

PBT is the go-to choice for typists and gamers who want a consistent, high-end feel without worrying about wear. It's especially popular in custom mechanical keyboard communities, where longevity and texture are prized.

Double-Shot PBT: The Best of Both Worlds?

Double-shot PBT isn't a separate material but a manufacturing technique applied to PBT keycaps. In this process, two layers of plastic are molded together: the outer shell (usually PBT) and the legend (often a different color of PBT or ABS). The legend is literally a separate piece of plastic that passes through the outer layer, creating a seamless, permanent marking. This makes double-shot PBT keycaps virtually indestructible in terms of legend durability—they cannot fade, rub off, or yellow over time. The result is a keycap that combines the toughness of PBT with the crisp, lasting clarity of double-shot legends. Many high-end sets, such as those available for the Keychron Q60 Max QMK/VIA Wireless Custom Mechanical Keyboard, feature double-shot PBT construction.

Pros of Double-Shot PBT

• Legends are permanent—no fading, no wear, no shine
• Extremely durable outer shell resists oil and scratches
• Excellent tactile feedback with a dense, premium feel
• Ideal for backlit keyboards, as legends can be translucent

Cons of Double-Shot PBT

• Higher cost due to complex manufacturing process
• Heavier than standard PBT, which may not suit all preferences
• Limited availability in certain profiles or colorways
• Thicker walls can reduce RGB brightness if not designed for shine-through

Double-shot PBT is considered the gold standard for keycap durability. If you plan to keep your keycaps for years and demand pristine legends, this is the material to choose.

Which Keycap Material Should You Choose?

Your choice ultimately depends on your priorities. If you're a casual user who values low cost and a familiar feel, ABS keycaps are perfectly fine—just be prepared for shine after a few months. For most typists and gamers, PBT keycaps offer the best balance of durability, feel, and price. The textured surface and resistance to wear make them ideal for daily use. If you want the ultimate in legend longevity and a truly premium typing experience, double-shot PBT is the way to go. It's the material used in many high-end custom keycap sets, and it pairs beautifully with boards like the Keychron Q7 QMK Custom Mechanical Keyboard.

How Keycap Material Affects Sound and Feel

Material isn't just about durability—it also dramatically alters the acoustics of your keyboard. ABS keycaps, being thinner and lighter, tend to produce a higher-pitched, more resonant sound. This can be desirable for certain switch types, such as clicky switches, where you want to emphasize the click. PBT keycaps, with their greater mass, dampen vibrations and create a deeper, thockier sound. This is especially noticeable on linear or tactile switches. Double-shot PBT, with its two-layer construction, adds even more mass, resulting in a solid, thud-like sound that many enthusiasts love. If you're using a wireless keyboard like the Keychron K8 Wireless Mechanical Keyboard (Japan JIS Layout), the material choice can also affect battery life indirectly—heavier keycaps require slightly more force to actuate, but the difference is minimal.

Pairing Keycaps with Your Keychron Board

Keychron offers a wide range of keyboards that benefit from upgraded keycaps. For example, the Keychron Q60 Max QMK/VIA Wireless Custom Mechanical Keyboard is a compact 60% board perfect for showcasing a custom set like the Pixel Universe double-shot PBT keycaps. Meanwhile, the Keychron Q7 QMK Custom Mechanical Keyboard offers a Southpaw layout with a full number row, giving you more real estate for creative keycap combinations. If you're building a themed setup, consider artisan keycaps like the Family Computer Aluminum Alloy Artisan Keycap to add a unique accent. And don't forget about switches—the Gateron Luciola Linear Switch pairs exceptionally well with PBT keycaps for a smooth, deep typing experience.

Care and Maintenance Tips

Regardless of material, proper care extends keycap life. For ABS, regular cleaning with a soft brush and mild soap can minimize shine. PBT and double-shot PBT require less maintenance but still benefit from occasional dusting. Avoid harsh chemicals like acetone, which can damage any plastic. Store spare keycaps in a cool, dry place to prevent warping. If you use a carry case, such as those available in the Carry Case category, you can protect your keycaps during transport.

Final Thoughts

Choosing between ABS, PBT, and double-shot PBT keycaps comes down to balancing budget, feel, and longevity. ABS is affordable but wears quickly, PBT offers excellent durability and texture, and double-shot PBT provides permanent legends and a premium thock. For most users, PBT or double-shot PBT is the smart investment. Ready to upgrade your typing experience?
