What is TPU material? What are its benefits? Introducing recommended TPU smartphone cases

There are many different types of smartphone case materials, and one that has recently been gaining attention is TPU (thermoplastic polyurethane). However, many people may be wondering, "What kind of material is TPU?" and "How is it different from other cases?" In this article, we'll take a closer look at the characteristics and benefits of TPU material, how it differs from other materials, and clearly explain who it's suitable for.

What is TPU material?

As its name suggests, TPU (thermoplastic polyurethane) is a flexible material that changes shape depending on the temperature. Originally used in industrial applications, this material is now used in a variety of products, including smartphone and iPhone cases , due to its excellent elasticity and durability. TPU has properties somewhere between plastic and rubber, making it a highly shock-resistant and abrasion-resistant material that provides excellent protection for your smartphone.

The flexibility and strength of TPU: TPU is as soft as rubber, yet retains a certain degree of hardness, making it ideal for protecting your smartphone from everyday drops and shocks. It also resists deformation even after long-term use, making it ideal for those who frequently remove their case.

One of the features of TPU is its high transparency, which allows it to show off the design of the smartphone itself. This makes it a great choice for those who want to enjoy the design of their smartphone as it is as a clear case. There are also a wide variety of colors to choose from, from transparent to matte and vibrant colors, so you can choose one that suits your preferences and needs.

Advantages of TPU material

TPU has many advantages that make it ideal for smartphone cases . Below are some of the main reasons why you should choose a TPU case:

Excellent impact resistance
TPU material is flexible and resilient, so it easily absorbs shock when your smartphone is dropped. A TPU case will give you peace of mind knowing that your smartphone will be well protected even from minor drops.
Grip that fits comfortably in your hand
The softness and moderate hardness of the TPU creates a comfortable grip that fits in your hand. The case is less slippery, making it easier to hold and reducing the risk of accidentally dropping your smartphone.
Transparency that doesn't impair the design
Another attractive feature of TPU material is its high transparency. If you want to show off your smartphone's beautiful design, we recommend a clear TPU case. Because it's highly transparent, you can still enjoy the original design of your smartphone even with the case on.
Lightweight and thin yet highly durable
The major advantage of TPU cases is that they are lightweight, thin, and durable. They are durable enough for everyday use, yet easy to carry and handle.
Good cost performance
TPU is also cost-effective and often reasonably priced for its durability, making it a great choice for those looking for a case that offers solid protection on a budget.

Disadvantages of TPU material

Although TPU has many advantages, there are some points to be aware of when using it. However, these points are not a major problem under normal use and do not significantly impair the convenience of TPU.

Caution required in high temperature environments
TPU is sensitive to heat, so if you leave it in a car or other high-temperature environment for a long time, it will easily lose its shape. It's not a problem for normal use, and you only need to be especially careful in extremely high temperatures.
Yellowing of transparent TPU
Clear TPU cases may yellow slightly over time, but they can be kept in good condition with simple care, such as wiping off dirt frequently.
It is easily stained with dirt and fingerprints
Because TPU material has a soft texture, it tends to attract oils from hands and fingerprints. However, many recent TPU cases have been treated with anti-fingerprint and anti-fouling coatings, which make them less likely to attract fingerprints and easier to wipe off. This allows you to keep the case clean for a long time.

Comparison of TPU phone cases with other materials

To understand the advantages of TPU phone cases, let's compare them with other phone case materials. By looking at the properties of each material, we can see how TPU is a well-balanced choice for phone protection.

Comparison with silicone cases
Silicone cases are also flexible and feel good to the touch, but TPU material is more durable than silicone and is less susceptible to dirt and dust. TPU is also a little harder than silicone, so it has the advantage of being easier to operate for people who frequently put on and take off their cases.
Comparison with PC (polycarbonate) cases
PC cases are hard and very durable, but their shock absorption is not as good as TPU's. On the other hand, TPU is flexible and effectively absorbs shock when dropped, protecting your phone. TPU is also lighter than PC, making it easier to hold and less slippery, making it suitable for everyday use.
Comparison with leather cases
Leather cases have a luxurious feel and attractive designs, but are expensive. On the other hand, TPU cases are more economical than leather, have better water resistance, are easier to maintain, and have stain and water resistance functions. TPU is also more shock-resistant than leather, making it a practical material for preventing drops.

Compared to silicone, PC, and leather, TPU material offers a good balance of durability, feel, and protection, making it a very practical choice for everyday smartphone use.

Key points for choosing a TPU phone case

TPU smartphone cases are a well-balanced material that offers excellent durability, feel, and cost performance, making them suitable for a variety of uses. When choosing a case, first consider how you will use it and the design of your smartphone, and then focus on the features and style that best suit your needs.

For example, if you carry your smartphone around a lot and often accidentally drop it, we recommend a shock-resistant TPU case. These cases have reinforced corners and a non-slip surface, so they will protect your smartphone from minor everyday shocks. The soft feel and moderate hardness of the TPU also give you a sense of security when holding it.

If you want to show off your smartphone's design, a transparent TPU case is a good choice. Highly transparent TPU protects your smartphone from scratches and dirt while maintaining its beautiful appearance. Many recent TPU cases are treated to prevent yellowing and fingerprints, making them attractive because they will stay beautiful for a long time without any special care.

A simple TPU case is ideal for those on a budget. TPU is affordable yet durable, making it perfect for those who value value for money. Plus, it's lightweight and thin, so it doesn't take up much space when you're carrying it around and fits easily in your pocket or bag.

Choosing a TPU case that suits your lifestyle will keep your smartphone safe and comfortable. As such, TPU cases offer a wide range of options to suit your needs and applications, making them an excellent choice for everyday smartphone cases.

The evolved version of the TPU case: TORRAS dual-material case

While TPU cases offer excellent flexibility and shock absorption, transparent TPU tends to yellow and can lose its shape under high temperatures. TORRAS cases use a PC back panel with excellent hardness and yellowing resistance, and TPU on the sides for a comfortable feel. This TPU section has been specially treated to make it less prone to yellowing than pure TPU cases.

TORRAS' dual-material case is an improved case that maintains the softness of TPU while pursuing durability and aesthetics, making it an ideal choice for those who want to keep their smartphone looking beautiful for a long time.
