INUTEQ® use CrodaTherm™ PCMs in Personal Cooling

Challenge

 INUTEQ wanted to use phase change materials (PCMs) that would provide body cooling during demanding physical activities around the globe.

As the product was to be used by consumers, it was vital that the chosen PCM was safe in use with no chemical labelling.

The selected PCM was also required to be compatible with encapsulation materials long-term to provide maximum cooling effect, time and time again.

We provided a range of CrodaTherm bio-based wax phase change materials for consideration by the INUTEQ that had:   

• High flash points
• Long term stabilities
• High latent heat capacities
• No corrosive properties
• No flammable labelling
• USDA bio-based certification

Expertise

Using our industry leading technical expertise, we were able to suggest CrodaTherm materials with different melting points so that the cooling vests would perform in many different environments, cooling the wearer to a comfortable temperature, no matter the location.   

To meet all specifications set by INUTEQ, we also developed a PCM that could provide temperature control at 15°C, whilst providing other PCMs already on the product range. This allowed INUTEQ to move away from the paraffin PCMs in all their products. 

We supported INUTEQ to ensure all CrodaTherm materials were compatible with the encapsulation materials, helped verify longevity of the finished article and advised on how to colour the PCM for different temperatures. 

Result

CrodaTherm bio-based wax is the superior choice of PCM, achieving the highest standards of safety, material compatibility and performance. 

Unlike paraffin and salt hydrate PCMs, CrodaTherm is bio-based, environmentally benign and does not require flammable or corrosive labelling. 

The resulting cooling vest allows the wearer to keep cool for up to 4 hours.

INUTEQ successfully supplies cooling vests containing CrodaTherm around the world into some of the most demanding occupation and leisure activities including cycling, motorsport and construction.

INUTEQ have capabilities to make bespoke cool-pack systems for various applications that can cool to 6.5°C, 15°C, 21°C, 24°C and 29°C.
