The Perils of Cycling in the Rain: Why Riders Need to Look Out for Their Phones

TPU shockproof cases for the Samsung Galaxy S23, including those distributed by Anbima, provide impact resistance using thermoplastic polyurethane. This material combines the flexibility of silicone with the durability of hard plastic to protect the device’s glass surfaces from drops and environmental hazards.

Thermoplastic polyurethane, or TPU, is a linear copolymer that functions as a bridge between hard plastic and soft silicone. According to technical specifications for shockproof accessories, TPU is chosen for smartphone cases because it absorbs kinetic energy during a fall, reducing the likelihood of the internal hardware or the external glass screen shattering upon impact.

What is TPU and how does it protect the Galaxy S23?

TPU provides a balance of rigidity and elasticity. While a hard polycarbonate case might crack under pressure and a soft silicone case may stretch or slip, TPU maintains its shape while absorbing shock. This makes it a standard choice for “anti-urto” or shock-resistant cases designed for devices like the Samsung Galaxy S23.

The material is also resistant to oils, grease, and abrasion. For users operating devices in wet conditions or high-activity environments, these properties prevent the case from degrading quickly. The Anbima listing emphasizes the utility of these cases in scenarios where a phone might be dropped during a commute or in inclement weather.

How do TPU cases compare to other materials?

Different case materials offer varying levels of protection and ergonomics. TPU differs from other common options in the following ways:

• Polycarbonate (PC): Hard plastic that offers high scratch resistance but can crack upon heavy impact.
• Silicone: Highly flexible and grippy, but often attracts lint and lacks the structural rigidity to protect corners from high-velocity drops.
• TPU: Offers the impact absorption of silicone with a higher structural integrity closer to polycarbonate.

Because TPU is more durable than silicone and more flexible than PC, it is frequently used in hybrid cases where a hard back plate is paired with TPU bumpers on the corners to maximize shock absorption.

Why is protection still relevant for the S23?

The Samsung Galaxy S23 features a glass front and back, making it susceptible to cracks from impact. Despite the release of newer iterations in the S-series, the S23 remains a widely used device in the secondary and primary markets, sustaining a demand for protective hardware.

The availability of TPU cases from third-party providers like Anbima ensures that users can maintain the physical integrity of the device without needing to replace the entire unit. This is particularly relevant for users who prioritize device longevity or intend to resell the hardware in the future.

Industry standards for “shockproof” certifications typically involve drop tests from specific heights onto hard surfaces. TPU’s ability to deform slightly and then return to its original shape allows it to dissipate the energy of a drop more effectively than rigid materials.
