What is a soft TPU case?
Asked by: scraper | Last update: August 28, 2026Score: 0/5 (0 votes)
A soft TPU case is a phone cover made of Thermoplastic Polyurethane—a hybrid material that is flexible like silicone but tougher than rigid plastic. It is highly prized for its shock-absorbing qualities, sleek profile, and ability to easily snap onto your device without scratching the edges.
Are soft TPU cases good?
Why TPU is ideal for phone cases. Phone case manufacturers love TPU for several reasons. Its flexibility allows the case to absorb shocks from drops, protecting your device better than rigid materials. TPU's soft texture provides a comfortable grip, reducing the chance of accidental drops.
Are TPU cases better than plastic?
TPU cases excel in impact resistance and offer flexible, shock-absorbing protection, making them ideal for users who prioritize durability. Plastic cases, on the other hand, deliver sleek, minimalist designs while maintaining adequate protection against scratches and everyday use.
What is the difference between soft and hard TPU?
Shore A (commonly used for TPU filament specifications): 60A–70A: very soft / “gummy”; can be hard to feed; often needs direct drive and slow speeds. 80A–88A: flexible but printable on many setups. 90A–95A: “stiffer TPU”; easiest flexible to print; still bends but less spaghetti-like.
What are the disadvantages of TPU cases?
The disadvantage is that it is too soft. Furthermore, due to the nature of the material, there is also the disadvantage that it is prone to dust and stains. Because of this, you may end up changing cases quickly.
Rubberized Hard Case vs. Silicone vs. TPU
What is the best TPU hardness for a phone case?
TPU filament vary in softness, often described by Shore hardness. Most phone cases use TPU in the 85A to 95A range because it offers a good mix of flexibility and durability.
Do all TPU cases turn yellow?
Just because clear cases made of polymers (e.g., TPU and silicone) all turn yellow over time due to things like UV light doesn't mean you can't still enjoy a clear phone case. You just need the right clear phone case.
What is the safest type of phone case?
The "safest" phone case depends on your specific needs, but top industry performers balance extreme drop resistance, grip, and material safety.
How long do TPU phone cases last?
TPU cases are popular because they are transparent and do not interfere with the design of your smartphone. They look nice at first, but over time they harden and change color. They last about 1-2 years. If you often pick up your phone or keep it in your pocket, you may want to consider replacing it sooner.
What does a soft TPU feel like?
85A (Soft Rubber): Best for comfort and grip. Feels like a shoe insole. Requires a Direct Drive extruder and slow speeds.
Which is better, TPU or silicone case?
TPU excels in elasticity, abrasion resistance, and chemical resistance, making it suitable for flexible, durable products. On the other hand, silicone boasts superior heat resistance, flexibility, and chemical inertness, making it a preferred choice for heat-resistant, soft-touch applications.
What TPU should I use for a phone case?
The best TPU (Thermoplastic Polyurethane) for phone cases is generally rated between 85A to 98A Shore hardness, with 95A being the most popular choice for 3D printing due to its balance of flexibility, durability, and ease of printing. This material offers high shock absorption and abrasion resistance, making it ideal for protection.
Do TPU cases interfere with wireless charging?
Polycarbonate/TPU Cases
Another reason wireless charging works with these cases is that they're nonconductive, which means they won't interfere with the charging process, whether you're using an iPhone 16 Pro or a Samsung Galaxy phone.
Are TPU phone cases safe?
In summary, TPU is generally considered a safe material for 3D printing and everyday products. Its unique chemical structure allows it to be both flexible and durable, while also exhibiting low toxicity.
Does TPU release microplastics?
Yes. Because Thermoplastic Polyurethane (TPU) is a synthetic elastomer derived from petrochemicals, it degrades over time and fragments into microplastics.
What are the cons of TPU plastic?
Disadvantages of TPU
Solvent-based finishing products might not bond well. In terms of longevity of the finish, flexibility might work against you if the finish is rigid. In worst-case scenarios, it might even cause cracks and peeling.
Is TPU a rubber or plastic?
TPU or Thermoplastic Polyurethane are a category of plastic created when a polyaddition reaction occurs between diisocyanate and one or more diols. They can be used as a soft engineering plastic or as a replacement for hard rubber.
How to remove yellowing from TPU case?
Step 1: Start by mixing the baking soda and water in a bowl. Step 2: Put your phone case into the mixture and let it soak for 30 minutes. Step 3: Remove the case from the mixture. If there are any stubborn yellow spots, sprinkle some more baking soda onto them, then scrub with the toothbrush.
Are there truly non-yellowing clear cases?
Crystal Guard Non Yellowing Case
True to its name, this non yellowing clear case did not show even a hint of yellowing.
Is hydrogen peroxide safe for clear cases?
Fill a container with hydrogen peroxide with enough space to cover the case and put the phone case in it for 2-3 hours. Rinse the case well with water after soaking. Dry the phone case completely before refitting it to your phone.
What case is stronger than OtterBox?
Are There Cases Better Than Otterbox? Exploring the 5 Best Otterbox Alternatives
- 3.1 Beeasy Case: MIL-STD-810G Certified Protection.
- 3.2 Casetify Case: Trendy Yet Protective.
- 3.3 Spigen Tough Armor: Dual Protection with Air Cushion Technology.

Which is softer, TPU 90 or 95?
TPU 90A is softer than TPU 95A. TPU hardness is measured on the Shore A scale. Lower numbers indicate a more flexible, rubber-like material, while higher numbers mean the plastic is stiffer and holds its shape better.
What is the best softness for TPU?
For stable printing, TPU with a hardness of 85A or higher is recommended. Softer TPU (such as 83A or 80A) bends easily during feeding, which can cause filament buckling, tangling, or unstable extrusion.
