A phone case is an essential mobile phone accessory that secures your phone and enhances the look of your phone. Mobile phone is not just a device, it’s a part of your identity as well.

So, when choosing a phone case, there are some things you might look for, which are

  • Protection

But, is that it?

Definitely Not!

In this article, we will talk about an essential aspect related to TPU phone cases that one should look for. So, if you’re the one that is looking to buy a new case for your smartphone, you are at the correct place.

TPU Material Case

When choosing a phone case, the most important decision is selecting the material of the smartphone cover.

Materials can make a huge difference in how protected the phone is and that’s where the TPU phone case comes in.

A TPU phone case is a cover made from thermoplastic polyurethane, which is designed in such a way that it protects your phone from scratches. In other words, it helps you keep your phone scratch-free.

It is lightweight and durable, which can withstand day-to-day wear and tear.

It is an excellent choice to make when you are buying a phone case, as it secures your phone as well as upscales the beauty of your phone as it comes in diverse designs.

Properties of a TPU Material Phone Case:

A TPU material case has some properties which can make it a top priority for you as a phone case.

  • It is flexible as the material has a high elasticity rate, and as it is a polymer, it possesses the shock absorbent property too.
  • It is heat-resistant, which is an important property, especially when it comes to gaming phones.
  • Its liquid-resistant property makes you extra comfortable when you are carrying this smartphone. It protects your phone from oil and grease stains as well.
  • It is completely recyclable.
  • The non-slip properties of TPU material ensure a more secure grip, reducing the chance of dropping the phone.
  • It is lightweight and easy to carry
  • It comes in various designs, enabling you to personalize your device to suit your style and personality.

TPU Material vs Other Materials:

Well, let’s be real here.

TPU case isn’t the only case material in the market. There are various other material cases from which you can choose from.

Let’s have a look at some of these case materials and understand why TPU Case stands out as the best;

TPU vs Silicone Cases:

When considering a phone case for your smartphone, TPU is far better than a silicone case. They are both polymer-based materials, and they are both effortless to produce.


TPU is better than silicone because it is a hard plastic material that covers the phone from the back and sides. Unlike regular plastic cases, they are more flexible and easily get attached to your phone.

It protects your phone way better than a silicone case could. If you drop your phone with a silicone case, you might have a phone with many scratches or cracks.

Dust Resistance

Some of the pros that silicone offers is that it protects your phone from dust and other materials in the air. In contrast, a TPU material phone case can easily attract dust particles, making your phone dusty every time.

But, when it comes to protection, which is the primary function because of which a person buys a phone case, the TPU material phone case is miles ahead.

TPU vs Metal Cases:

If you’re looking for a phone case that protects your phone perfectly and provides aesthetics as well, then TPU and Metal cases can prove to be mind-boggling.

Let us dive deep into both materials and see what they have to offer.

Basic Properties:

TPU, known for its flexibility and shock absorption capabilities, provides excellent protection against incidental drops.

On the other hand, metal cases have a premium and luxurious look and are highly resistant to scratches, maintaining their pristine look over time.

TPU cases might not possess the aesthetically pleasing vibe that a metal case gives off, but it offers something more precious than that, which is securing your phone.

Case Bulk:

TPU cases are lightweight, offering less bulk, a minimalist look, and a comfortable grip. In contrast, metal cases are bulky and make your phone slightly heavier. They provide some aesthetic looks but make the device less comfortable for you to hold.


They are both durable, resistant to everyday wear and tear, and can withstand scratches and scuffs. But, a solid impact on your metal case can cause its deformation.

TPU vs Hybrid Cases

If you’re looking to armour your phone, the TPU and Hybrid cases might be your choice. But which one to select? In this case, we’ll help you as we unravel the unique features and strengths they bring.


TPU cases are made from thermoplastic polyurethane, providing unique features such as shock absorption and flexibility. At the same time, Hybrid cases are made from different materials to provide better protection and special features.


TPU case protects your phone from in and out, providing excellent protection against incidental drops. Whereas hybrid cases, made from different materials, offer protection by combining the characteristics of different materials such as silicone, TPU and others, effectively absorbing and distributing impact forces.

Flexibility and Grip:

TPU material is flexible, providing you with a comfortable grip when you are holding your phone. In contrast, Hybrid cases with TPU or silicone inner layers offer a similar level of flexibility and grip as TPU cases, providing a comfortable grip on the phone.

Maintaining and Cleaning Your TPU Phone Case

Generally, if you opt for the longevity of the smartphone case, you must maintain and clean your TPU case once in a while.

Following are some of the tips that can be helpful for you in keeping your TPU case in good shape.

Regular Cleaning:

Wiping your TPU case with a soft cloth to remove dirt, dust, and fingerprints is a must once every week. If you require deep cleaning, you can use a mild soap or detergent, but prevent the use of harsh chemicals.

Maintain Temperature:

It is necessary to maintain the temperature of your device as TPU material is sensitive to extreme temperatures. So, to prevent any damage, keep your phone and case away from direct sunlight or hot surfaces.

Gentle Handling: 

The TPU case is flexible, but due to hard plastic, excessive bending can cause deformation or weakening of the material.

Phone Cleaning:

It is recommended to take off your phone case occasionally and deeply clean your phone and case. This helps prevent the scratches that some kind of dust or debris buildup inside the case can cause on the back of your phone.

Inspect for Damage:

If you want to upscale the protection of your phone, it is advised to take off your TPU phone case and inspect for signs of wear, tears, or cracks. Replace the case if you notice any damage to maintain optimal protection.

Environmental Impact:

In today’s eco-conscious world, manufacturing the product while understanding its environmental impact is essential. In that regard, TPU cases have turned people towards themselves, not only for their flexibility, design or security but also for their relatively favourable environmental characteristics compared to different materials.

TPU’s Eco-Friendliness: A Step Towards Sustainability

TPU (Thermoplastic Polyurethane) is considered a more eco-friendly choice for phone cases when compared to other types of materials. The main property attracting people towards itself is its recyclability.

TPU can be melted down and reprocessed into new products, reducing waste. Proper recycling methods are necessary to maximize TPU’s eco-friendliness.

Moreover, TPU production generates fewer greenhouse gas emissions than manufacturing certain plastics like polycarbonate. Lower emissions contribute to a reduced carbon footprint, making TPU phone cases a better choice for environmentally-conscious consumers.


In conclusion, TPU material phone cases perfectly blend style and protection. Their flexible and shock-absorbing properties can withstand accidental drops and solid collisions and help you keep your phone scratchless.

Their lightweight and slim shape provides comfort while holding your phone without compromising protection.

Moreover, various colours and textures allow users to personalise their phone cases, adding a hint of uniqueness to their phones.

Additionally, because of their low price, they are also very pocket-friendly. And having a feature of recyclability, they also provide no harm to the environment, thus are eco-friendly.

So, when looking for a phone case manufacturer in China or a custom phone case manufacturer, consider TPU material for a perfect blend of style, functionality, and sustainability.
