Phone cases are an essential accessory for many people as they protect their smartphones and offer a sleek and elegant design. However, when a clear phone case turns yellow it can mar the aesthetic and look of a device. This article explores the causes of this issue and offers preventative measures to help you enjoy your clear smartphone case for as long as possible.
The majority of clear cases on the market are made from TPU (Thermoplastic Polyurethane), silicone, or polycarbonate. While TPU provides a good combination of shock absorbency, scratch resistance, oil and grease repellence and durability, it is prone to yellowing when exposed to sunlight, water, sweat and other environmental factors. The chemistry of TPU causes it to degrade over time, which ultimately results in the discoloration of the plastic.
Silicone and polycarbonate, on the other hand, are more resistant to yellowing and provide better protection against scratches and drops. They also feature an anti-yellowing coating, which helps to keep a clear appearance. If you are considering purchasing a clear case, be sure to read the product descriptions and compare the materials to make an informed decision.
To ensure your clear phone case stays crystal-clear, it is important to regularly clean the surface of the case. This can be done using a mixture of equal parts water and isopropyl alcohol. Simply apply the solution to a soft cloth and gently wipe down the front and back of the case, making sure to include the corners and charging port hole. Leave it to dry completely before putting it back on your phone. Clear Phone Cases
