Silicone vs TPU vs polycarbonate: which case material is best?

Three materials dominate phone cases, and they behave very differently. Here's the honest breakdown.

Silicone is soft and grippy, pleasant in hand, but it attracts lint, can stretch and discolour over time, and doesn't hold a printed design sharply. TPU (a flexible plastic) is the budget default: shock-absorbing and cheap, but it yellows notoriously, especially the clear versions, and prints on it tend to sit on the surface and wear off. Polycarbonate is a rigid, premium plastic — harder, slimmer, and the only one of the three that takes a UV-cured print crisply and permanently, because the pigment fuses into the surface rather than layering on top.

The trade-off is real: silicone wins on softness, TPU wins on price, polycarbonate wins on print quality, slimness and longevity. Miarobi uses a dual-layer build with a polycarbonate print surface precisely because we treat the design as the product — and a design is worthless if it fades or peels. If you want a case that still looks like the day you bought it a year later, and a print that reads as art rather than a sticker, polycarbonate is the answer. That's why every Miarobi case is built on it, backed by a 9-month print warranty.
