Ice Ring FAQs

How does the ice ring work?

The ice ring features a TPU surface filled with PCM (phase change material).

This material has the ability to absorb and release heat, providing a cooling sensation when worn.

It stays cool at 28 °C or 82.4°F, making it perfect for hot weather, exercise, or working under high temperatures.

How does it freeze under tap water?

It freezes under tapwater because typically tap water is less than 28 °C or 82.4°F, and at that temperature, the PCM inside will solidify.

Please ignore if you have boiling or really hot tapwater… In that case you should try cooling it with ice water or in a fridge

How do I use the ice ring?

Using the ice ring is simple. Place it anywhere with a temperature of less than 28 °C or 82.4°F. Once cooled into a solid, wear it around your neck for instant cooling relief.

Who is it for?

The ice ring is suitable for individuals who want to stay cool in hot weather, during exercise, or while working in high-temperature environments.

It can be beneficial for outdoor enthusiasts, athletes, workers in hot climates, or anyone seeking relief from the heat and a cooling sensation around the neck area.

Is it even cold?

Yes, the ice ring is designed to provide a cooling sensation. The temperature of 28 °C or 82.4°F is perfect because it’s not damaging to your skin, yet it’s lower than your body temperature so you would still feel cool.

Anecdote: Sometimes your hands are cold, and you would feel a cold sensation if you touch your face with your cold hands. It’s kind of like that, so it’s not freezing cold yet still cool enough.

How long does the ice ring stay cool?

The ice ring's cooling effect can last for a significant duration, depending on the surrounding temperature and usage.

On average, it provides cooling relief for approximately 1-3 hours.

Why is this better than just any plastic tube?

PCM is like a special material that is really good at staying cool. It needs a lot of heat to make it change its temperature.

That's why it can stay cold for a longer time and help you feel nice and cool when you wear it. Other materials don’t work the same way and doesn't stay cool for as long.

Does it soak your shirt due to condensation?

No, it usually does not have condensation. The only exception is if you have just taken it out of the freezer.

It is not recommended to use it when it’s cooled to a temperature of under 10 °C or 50 °F.

Is the ice ring reusable?

Yes, the ice ring is reusable. After each use, simply cool it with tap water for it to regain its cooling properties.

It can be used again and again whenever you need relief from the heat.

Is the ice ring adjustable?

Yes, you can bend the ice ring slightly outwards. However please be careful not to over bend it.

Is the ice ring safe to use?

Yes, the ice ring is designed with safety in mind. The TPU and PCM used in the product is non-toxic and safe for use against the skin.

However, it's important to follow the instructions provided and avoid wearing it for an extended period or if you experience any discomfort or allergic reaction.

Can I use the ice ring for medical purposes?

While the ice ring provides a cooling sensation, it is not intended as a medical device.

If you have specific medical conditions or concerns, it's recommended to consult with a healthcare professional before using the ice ring or any other cooling products.

Can children use the ice ring?

The ice ring can be used by children, but adult supervision is recommended, especially for younger children, to ensure proper usage and prevent any mishaps.

The ice ring should not be used by infants or children under 8.

What is TPU?

TPU is used for the surface of the ice ring. TPU stands for thermoplastic polyurethane.

It is a flexible and durable material commonly used in various applications due to its excellent physical properties, such as high elasticity, resistance to abrasion, and chemical resistance.

What is PCM?

PCM is used to fill the ice ring. PCM stands for phase change material. It is a substance that can absorb or release thermal energy when it undergoes a phase transition, such as changing from a solid to a liquid or vice versa.

In the case of the ice ring, the PCM inside it absorbs heat from the body, providing a cooling effect.

Would I be allergic to it?

If you are known to be allergic to TPU or PCM, please do not use it.

If you experience any discomfort during use, please stop use immediately and consult a doctor.
