Is TPU or silicone better for keyboard cover?



When it comes to protecting our beloved keyboards, keyboard covers are essential accessories. They provide a layer of protection from dust, spills, and even potential damage. However, choosing the right material for your keyboard cover can be quite challenging. Two popular options in the market are TPU (Thermoplastic Polyurethane) and silicone. Both materials have their pros and cons, and determining which one is better can make a significant difference in the overall performance and longevity of your keyboard cover. In this article, we will delve into the qualities of TPU and silicone, comparing their attributes, durability, flexibility, and overall user experience to help you make an informed decision.

The Advantages of TPU Keyboard Covers

Thermoplastic Polyurethane (TPU) is a versatile material known for its exceptional durability and flexibility. It is often used in various industries, including medical devices, automotive components, and electronic accessories. TPU keyboard covers offer several advantages that make them a popular choice among many users.

TPU keyboard covers are highly resistant to wear and tear. They can withstand everyday use while maintaining their shape and protective properties. The material has excellent abrasion resistance, which ensures long-lasting protection for your keyboard. Additionally, TPU covers provide a barrier against spills, dust, and dirt, keeping your keyboard clean and safeguarded from potential damage.

Another advantage of TPU keyboard covers is their remarkable transparency. Unlike other materials, TPU is optically clear, allowing you to see the keys clearly without any hindrance. This feature is particularly important for those who rely heavily on markings and symbols on their keyboard keys. With a TPU cover, you can have peace of mind knowing that your typing experience won't be compromised.

TPU covers are also known for their ease of cleaning. They can be easily wiped with a damp cloth or even washed with mild soap and water. This convenience ensures that your keyboard remains hygienic and free from any build-up of dirt or grime. It is important to note, however, that TPU material can be sensitive to certain chemicals or solvents, so it is crucial to avoid using abrasive cleaners or harsh chemicals that could damage the cover.

The Pros and Cons of TPU Keyboard Covers

While TPU keyboard covers offer numerous advantages, it is essential to consider the potential drawbacks as well.

One of the drawbacks of TPU covers is their relatively higher price compared to other materials. The premium quality and durability of TPU come at a cost, making them a bit more expensive than some alternative options. However, considering the long-term protection they provide and their ability to resist yellowing or discoloration over time, the investment may be worthwhile.

Another factor to consider is the slight change in typing sensation that TPU covers may cause. Due to the added layer on top of the keys, some users may find that the keys feel slightly softer or have reduced tactile feedback. Although this change is minimal, it is worth noting for those who prefer a more tactile typing experience.

The Advantages of Silicone Keyboard Covers

Silicone keyboard covers have gained popularity in recent years for their unique set of advantages. Silicone is a soft, flexible material that offers excellent elasticity and resistance to stretching. Let's explore the benefits that silicone keyboard covers bring to the table.

One of the advantages of silicone covers is their ease of installation. They are designed to fit snugly over the keys, providing a secure and precise fit. Silicone's flexibility allows for effortless application and removal, making it convenient for users who frequently switch between using a cover and going cover-free.

Silicone covers also provide a cushioned typing experience. The material absorbs the impact of keystrokes, resulting in a quieter typing sound and reducing typing fatigue for those who spend extended periods at their keyboards. This quality is particularly beneficial for individuals who work in shared spaces or prefer a more "muted" typing experience.

Additionally, silicone is a waterproof material, making silicone keyboard covers resistant to liquid spills. This feature enhances the protection level, safeguarding your keyboard from accidental spills or crumbs that may fall between the keys. Silicone covers are also effortless to clean since they can be washed with soap and water or quickly wiped with a damp cloth.

The Pros and Cons of Silicone Keyboard Covers

While silicone keyboard covers offer unique advantages, it is important to consider their potential shortcomings as well.

One of the drawbacks of silicone covers is their reduced transparency compared to TPU covers. Due to their inherently opaque nature, silicone covers may obstruct the markings or symbols on the keys, making it harder to see and use them. This can be particularly problematic for individuals who rely heavily on visual cues while typing. However, it is worth noting that some silicone covers are designed with semi-transparent or clear areas to alleviate this issue.

Another consideration is the longevity of silicone covers. Over time, silicone may begin to deteriorate due to exposure to UV rays, heat, or continuous stretching. This can result in the cover becoming sticky or developing cracks. However, with proper care and maintenance, such as keeping the cover away from direct sunlight or extreme temperatures, the lifespan of the silicone cover can be extended.

The Decision: TPU vs. Silicone Keyboard Covers

Ultimately, the choice between TPU and silicone keyboard covers depends on your specific needs and preferences. Here are a few key points to consider:

- If durability, transparency, and easy cleaning are your top priorities, TPU keyboard covers might be the right choice for you. They offer excellent protection, unparalleled transparency, and effortless maintenance, ensuring a long-lasting and comfortable user experience.

- If you prefer a softer and more cushioned typing experience, easy installation and removal, and resistance to spills, silicone keyboard covers may be a better fit. They provide a quieter typing sound, enhanced comfort, and waterproof properties, making them suitable for various scenarios.

In conclusion, both TPU and silicone keyboard covers have their own unique advantages and disadvantages. It is important to assess your specific needs, typing style, and budget before making a decision. Whether you opt for the durability and transparency of TPU or the cushioned typing experience and easy installation of silicone, a keyboard cover will undoubtedly protect your keyboard and extend its lifespan.


Choosing the right keyboard cover material is crucial for the overall protection and user experience of your keyboard. TPU and silicone are both popular choices in the market, each offering distinct qualities and advantages.

TPU keyboard covers excel in durability, transparency, and ease of cleaning. They provide long-lasting protection, clear visibility of the keys, and effortless maintenance. However, they can be slightly more expensive and may alter the typing sensation.

On the other hand, silicone keyboard covers offer convenient installation and removal, a cushioned typing experience, and resistance to liquid spills. They are ideal for individuals looking for a softer typing feel and extra protection against accidental spills. However, they may be less transparent and have a shorter lifespan.

Ultimately, the decision between TPU and silicone keyboard covers depends on your individual preferences and priorities. By considering the pros and cons mentioned above, you can make an informed choice that suits your needs and ensures the longevity of your keyboard. Remember, whichever material you opt for, a keyboard cover will undoubtedly provide an extra layer of protection and peace of mind for your beloved keyboard.
