Keychronus

When you first dive into the world of mechanical keyboards, the sheer number of customization options can be overwhelming. But one of the most critical decisions you'll make—often after choosing your switches and keyboard chassis—is selecting the right keycap material. The material of your keycaps directly influences how they feel under your fingers, how long they last, and even how your keyboard sounds. The three most common materials are ABS, PBT, and double-shot PBT. In this guide, we'll break down each type, compare their pros and cons, and help you decide which is best for your typing style and budget.

What Are Keycaps Made Of? Understanding Keycap Materials

Keycaps are the plastic covers you press on your mechanical keyboard switches. They come in various profiles (like OEM, Cherry, SA, etc.) and materials. The material determines not only the surface feel and sound but also how resistant the legends (the printed letters) are to fading. The most common materials are ABS (Acrylonitrile Butadiene Styrene) and PBT (Polybutylene Terephthalate). Double-shot PBT is a manufacturing process that uses two layers of plastic to create legends that never wear off.

ABS Keycaps: The Classic Choice

ABS is the most widely used plastic in the keyboard industry. It's the same material found in most stock keyboards, including many from major brands. ABS keycaps are known for their smooth, slightly glossy feel out of the box. They tend to be softer than PBT, which gives them a more muted sound when typing—often described as a deeper, thockier tone. However, ABS has a notorious downside: it develops a shiny, greasy appearance over time, especially on frequently used keys like the spacebar and WASD cluster. This is called "shining" and is caused by the natural oils from your fingers wearing down the surface texture.

• Pros: Smooth feel, good sound profile (darker, thockier), affordable, widely available.
• Cons: Prone to shine and wear, legends can fade over time (unless double-shot), less durable than PBT.

PBT Keycaps: The Durable Workhorse

PBT is a tougher, more resistant plastic than ABS. It's denser and less porous, which means it resists oil absorption and maintains a matte, textured surface for much longer. PBT keycaps feel slightly rougher under the fingertips—many users appreciate this texture for better grip and a more tactile typing experience. They are also more resistant to heat and UV light, so they won't yellow as quickly as white ABS keycaps. The downside is that PBT is harder to mold, so it's traditionally more expensive and can have slight shrinkage or warping issues in complex shapes. For a premium upgrade that combines durability with beautiful aesthetics, consider the OEM Dye-Sub PBT Keycap Set - Wheat Grey, which offers a warm, neutral palette with long-lasting dye-sublimated legends.

• Pros: Very durable, resists shine, maintains texture, UV resistant, better for heavy typists.
• Cons: Slightly more expensive, can have minor shrinkage, feels rougher (some prefer smoother).

Double-Shot PBT: The Gold Standard for Legends

Double-shot molding is a process where two different plastics are injected into a mold at the same time, creating a single piece with two layers. The outer layer is one color (usually the keycap base), and the inner layer forms the legend. This means the legend is physically part of the keycap—it can't wear off. Double-shot PBT keycaps combine the durability of PBT with the longevity of double-shot legends. They are the most resistant to fading, shine, and wear. The legends are also backlight-friendly if the inner plastic is translucent. For instance, the Cosmic Galaxy - Cherry Profile Dye-Sub PBT Full Keycap Set uses dye-sublimation on PBT for vibrant, fade-resistant graphics. Double-shot PBT is often the premium choice for custom builders who want their keyboard to look pristine for years.

• Pros: Legends never fade, extremely durable, resistant to shine and UV, excellent for backlighting (with translucent legends).
• Cons: Most expensive option, limited color combinations compared to dye-sub, can be heavy (affects typing feel for some).

ABS vs PBT vs Double-Shot PBT: A Head-to-Head Comparison

Feature	ABS	PBT	Double-Shot PBT
Durability	Low (shines easily)	High	Very High
Legend Longevity	Low (fades with use)	High (dye-sub or laser)	Infinite (molded-in)
Surface Texture	Smooth, becomes shiny	Matte, slightly rough	Matte, textured
Sound Profile	Dark, thocky	Lighter, clackier	Similar to PBT
Cost	Low	Medium	High
Backlight Compatibility	Good (shines through)	Poor unless double-shot	Excellent (with translucent legends)

How Keycap Material Affects Typing Feel and Sound

Your keyboard's sound and feel are influenced by the keycap material. ABS is softer and tends to absorb more vibration, resulting in a deeper, more muted sound. PBT is harder and transmits more vibration, giving a crisper, brighter clack. The weight of the keycap also matters: double-shot PBT keycaps are slightly heavier than single-shot ones, which can make the keystroke feel more solid and deliberate. If you prefer a quiet, thocky keyboard, ABS might be your choice. If you like a lively, tactile response, PBT or double-shot PBT is better. The profile also plays a role—for example, Cherry profile keycaps (like those in the Cosmic Galaxy set) offer a lower, more ergonomic shape that many typists prefer.

Which Keycap Material Is Best for You?

Choose ABS If:

• You want a smooth, classic feel and don't mind some shine over time.
• You're on a tight budget and need affordable keycaps.
• You prefer a deeper, thockier typing sound.
• You plan to replace keycaps frequently (e.g., for different sets).

Choose PBT If:

• You type heavily or for long hours and want a non-slip texture.
• You want keycaps that will look new for years.
• You prefer a matte surface and a brighter, clackier sound.
• You want good value for money—PBT is the sweet spot for durability and cost.

Choose Double-Shot PBT If:

• You want the absolute best durability and legend longevity.
• You plan to use backlighting and want the legends to glow evenly.
• You are building a premium custom keyboard and want the highest quality.
• You don't mind paying more for a set that will last a lifetime.

Pairing Keycaps with Your Keyboard

Once you've chosen your keycap material, you need to ensure compatibility with your keyboard. Most mechanical keyboards use a standard Cherry MX stem, but some layouts (like Alice or ISO) may require additional keys. For example, if you own an ergonomic keyboard like the Keychron V10 Max (Alice Layout) QMK/VIA Wireless Custom Mechanical Keyboard, you'll need a keycap set that includes a split spacebar and possibly a 1.75u right shift. PBT and double-shot PBT sets from Keychronusshop offer comprehensive coverage for most layouts.

Maintaining Your Keycaps: Tips for Longevity

Regardless of material, proper care extends keycap life. For ABS, avoid prolonged exposure to sunlight (which accelerates yellowing) and clean with a mild soap solution. For PBT and double-shot PBT, occasional cleaning with a soft brush and isopropyl alcohol keeps them looking fresh. Never use harsh chemicals or abrasive sponges. Storing keycaps in a cool, dry place prevents warping. If you want to add a personal touch, artisan keycaps like the Smile Aluminum Alloy Artisan Keycap can be added to your Esc or spacebar for a unique accent—they're made from aluminum, not plastic, and fit standard MX stems.

Final Verdict: Which Keycap Material Wins?

There is no universal "best" keycap material—it depends on your priorities. If you value longevity and a consistent texture over time, PBT or double-shot PBT is the clear winner. If you want the most affordable entry point and a classic smooth feel, ABS is fine. For the most durable legends and premium feel, double-shot PBT is unmatched. The good news is that Keychronusshop offers a wide range of keycaps in all three materials, so you can experiment and find what suits your fingers best.
