What is TPU

TPU stands for ‘Thermoplastic Polyurethane’. The material appears rubber-like, which means it is very elastic, flexible, and smooth to the touch, but at the same time, it is extremely durable and strong.

The TPU we use in our products offers high durability, food-safe and it's lab tested to be BPA free and also free of any known harmful chemicals. It also possesses excellent resistance to oils, greases, and solvents.

In addition, the TPU range also offers new possibilities for increased sustainability, by reducing carbon footprint without compromising on quality or performance. Our TPU in particular, in comparison to fossil-based TPUs, the carbon footprint can be reduced by more than 20 percent.


- TPU is 100% recyclable and biodegradable.

The TPU we use is more eco-friendly than most other plastics. It is an advanced material that is much more environmentally friendly than alternatives such as PVC or silicone since TPU is recyclable and biodegradable in 3 - 5 years.

- TPU is durable

TPU is abrasion resistant, giving it the ability to maintain appearances and physical integrity against scratches or scrapes. As one of the tougher materials on the market, TPU has a high-strength composition. This means that it is very, very tough to break in normal circumstances, in contrast, to e.g., silicone. Because of its abrasion resistance, it can also withstand impacts and is resistant to many chemicals and substences.

- TPU is a non-toxic and 100% food-safe material

TPU does not contain any chemicals that interfere with endocrine and hormone systems, nor does it contribute to PH change in food or water. It contains no dangerous ingredients according to REACH Compliance (EC) No 1907/2006.

- TPU has a high liquid resistance

TPU is also resistant to oil, grease, and stains, which makes it ideal for keeping up its appearance while safeguarding items from liquids. Further, TPU is water and moisture resistant, reducing bacterial home creation.

Why not silicone?

TPU has the same good properties as silicone, but is better for the environment, as it is both developed and can be disposed of/recycled in the best way.

The main problem with silicone is that the material is not a very ideal vacuum container. There's are bigger gaps in the material of silicone in comparison to TPU, making it unable to hold vacuum for a long period of time. Whereas with our TPU material we have tested again and again that it's able to hold vacuum for more than 3 weeks under room temperature.

Another reason to why we have chosen TPU and not silicone is durability. Silicone materials are poorer lasting. Continuous use wears silicone products out and the silicone turns gooey and sticky.

Though silicone is a great material and have some great properties, for a teether we have chosen to use TPU, that surpasses silicone in its properties and qualities.
