why phone case turns yellow, anti-yellow phone case India, best transparent phone cover

Clear cases are popular because they show off the original phone design. But yellowing is the biggest complaint among users.

The Science Behind Yellowing

Most transparent cases are made from TPU. When exposed to:

• Sunlight (UV rays)

• Heat

• Sweat & skin oils

• Pollution

The material oxidizes, leading to discoloration.

How to Avoid Yellowing

✔ Choose anti-yellow coated materials
✔ Look for UV-resistant claims
✔ Avoid ultra-thin low-cost TPU cases
✔ Choose hybrid hard-back + soft-frame designs

High-quality transparent cases are engineered to slow down oxidation significantly.

If clarity matters to you, material selection matters even more.
