The Problem with Transparent iPhone Cases: Why They Turn Yellow Over Time

It's no secret that transparent iPhone cases tend to develop an unsightly yellow tint after a few weeks of use.

But this issue isn't exclusive to iPhone cases; it affects all clear cases made from a specific material.

If you haven't seen what a yellowed case looks like, take a look at the "before and after" image of a transparent iPhone case below.

Unfortunately, this yellowing isn't something you can simply wipe away with a damp cloth; it's an irreversible transformation caused by certain chemical reactions.

So, why do most transparent cases turn yellow after a while? Let's delve into the causes of this coloration in clear cases:

Material Matters:

The primary culprit behind yellowing cases is the material used.

Many clear cases on the market are constructed from Thermoplastic Polyurethane (TPU) due to its numerous advantages, such as transparency, flexibility, and good impact absorption.

However, while TPUs are transparent, they are not as crystal clear as they appear to be.

In reality, they tend to have a subtle yellowish tint, and manufacturers often make adjustments to give them that clear appearance we desire.

Under the right conditions, these cases can remain transparent indefinitely.

However, once these conditions are compromised, the case reverts to its naturally "transparently yellow" state.

The two primary conditions that lead to yellowing in TPUs and subsequent degradation are:

Ultraviolet (UV) Radiation from the Sun:

Sunlight contains UV rays, which are electromagnetic waves.

When these rays interact with TPUs, they break down the molecules, leading to degradation and discoloration.

The extent of this process depends on the intensity and frequency of sun exposure.

Moisture and Dirt:

Moisture and dirt are the enemies of transparent objects, leaving behind unsightly coatings.

Moreover, moisture from sweat and other bodily secretions, which contain salts, oil, and mild acidity, can be corrosive to TPUs.

When combined with dust, dirt, and oily residues, sweat and sunlight can accelerate the yellowing process of transparent cases.

The Solution: Anti-Yellowing Cases:

Thankfully, many manufacturers have developed solutions to combat the yellowing problem in transparent cases by utilizing premium materials and advanced technology. EnduraClear™.

Introducing EnduraClear™ Clear Technology:

EnduraClear™ is an innovative X.One UV Coating technology designed to address the issue of yellowing in transparent cases.

It combines TPU and Acrylic material to create a case that remains crystal clear even when exposed to extreme conditions like UV radiation and moisture.

This technology sets these cases apart and has been independently tested and certified by SGS, a globally recognized organization.

In a 48-hour Light Ageing Test UV conducted by SGS, X.One’s Dropguard Pro(Magsafe Compatible) series remained clear, while a case without EnduraClear™ turned yellowish under the same conditions.

Why Choose X.One Dropguard Pro with EnduraClear™

X.One has been producing clear cases for years, but the ones that are cured with EnduraClear™ is the clearest and most anti-yellowing option available.

It combines TPU and Acrylic to create a durable impact-protection case that retains its clarity over time.
