Understanding the Material: TPU and Yellowing
Most clear phone cases on the market are made of a material called Thermoplastic Polyurethane (TPU). TPU is a polymer elastomer that offers elasticity, transparency, and resistance to oil, grease, and wear. These properties make it a popular choice for clear cases. However, TPU is susceptible to yellowing when exposed to UV rays, water, sweat, dirt, and other environmental factors. This yellowing is a result of an irreversible chemical reaction in the material.
TPU’s transparency allows it to showcase the design of the phone, but it also means that it is more prone to discoloration. When UV rays, which are a form of electromagnetic radiation, interact with the TPU polymer chains, they break down the molecular structure and cause the material to turn yellow over time. This reaction is irreversible and leads to the discolored appearance of clear cases. Additionally, natural oils and sweat from the skin can transfer onto the case, further contributing to the yellowing process.
To better understand the yellowing phenomenon, it’s important to delve into the material science behind TPU. TPU consists of long chains of repeating units, called monomers, which are linked together through chemical bonds. When exposed to environmental factors like UV light, these bonds can degrade and result in color changes. The extent of yellowing depends on various factors such as the quality of the TPU, the intensity and duration of UV exposure, and the presence of other substances like oils and sweat.
Table: Factors that Contribute to Yellowing of Clear Cases
| Factors | Description |
|---|---|
| UV Light Exposure | Exposure to UV rays breaks down the molecular structure of TPU, leading to yellowing. |
| Natural Oils | Transfer of natural oils from the skin onto the case can contribute to discoloration. |
