TPU is considered a hard plastic phone case with some soft parts too. They manufacture TPU cell phone cases to fit perfectly on your device. It is quite common to find that both TPU and silicone cell phone cases cover the back and sides of your cell phone. TPU cell phone cases are light and do not make your cell phone feel bulky at all.

TPU is typically used as an inner lining with a shell over it to protect the phone. While this offers the best in protection, it can add a bit too much bulk for users who prefer a slender case. The good news is that it doesn’t have to be an either/or type of purchase.
