ABS vs. PBT: The Difference in Keycap Materials for Gaming Keyboard
When selecting a mechanical keyboard, the choice of keycap material can often be a perplexing one, with many individuals doubting between ABS and PBT keycaps. This article aims to delve into the specific characteristics of both materials to assist you in making an informed decision.
ABS and PBT are two widely used materials in the production of keycaps, each possessing unique properties in terms of touch, sound, and appearance. Generally speaking, ABS keycaps are renowned for their affordable price, smooth surface, and pleasant texture. However, after prolonged use, the surface may begin to acquire a shine. Conversely, PBT keycaps, despite their higher cost, stand out due to their superior quality, unique texture, and remarkable durability. The surface of PBT keycaps is less prone to oil buildup, ensuring a consistently fresh feel during use.
ABS Keycaps
ABS keycaps are the most common material used for keycaps. Its chemical name is Acrylonitrile Butadiene Styrene plastic, which is one of the five major synthetic resins. It offers excellent impact resistance, heat resistance, low temperature resistance, chemical resistance, and electrical properties. It is also easy to process, ensuring stable product dimensions and a good surface gloss. Its surface can be easily painted, colored, and subjected to secondary processes such as surface metal spraying, electroplating, welding, hot pressing, and bonding. Therefore, ABS keycaps are a popular choice among keyboard manufacturers. Its strong plasticity, combined with a pleasant texture and light weight, makes it a preferred material for many keyboards.
However, ABS keycaps also have some limitations. One of the main drawbacks is their poor wear resistance. Over time, the surface can become increasingly shiny, and the lettering may fade.
PBT Keycaps
PBT keycaps, on the other hand, are made from a high-heat-resistant material known as polybutylene terephthalate. It offers exceptional toughness, fatigue resistance, self-lubrication, and low friction. PBT is one of the most resilient engineering thermoplastic materials available. It is a semi-crystalline material with excellent chemical stability, mechanical strength, electrical insulation properties, and thermal stability. These properties make it highly suitable for a wide range of environmental conditions.
Compared to ABS keycaps, PBT keycaps offer superior wear resistance and greater hardness. These attributes come with a higher level of production complexity and cost, which results in PBT keycaps being less common on the market. Keyboards equipped with PBT keycaps often carry a higher price tag due to their exceptional durability and longevity. Despite this, many mechanical keyboard manufacturers have begun to favor PBT keycaps due to their exceptional wear resistance and extended service life.
In conclusion, the choice between ABS and PBT keycaps ultimately depends on personal preferences and budget considerations. If you prioritize a keyboard with a luxurious feel and a long-lasting finish, PBT keycaps are likely the better choice. On the other hand, if cost-effectiveness and a pleasant texture are more important to you, ABS keycaps may be a more suitable option. Nevertheless, regardless of your choice, it is essential to maintain cleanliness and replace the keycaps regularly to ensure your mechanical keyboard remains in top condition for years to come.
