Sustainable TPE Materials for Aroma Diffusers 

The scent of pine, florals, fruits or aromatic wood is just an olfactory experience away with aroma diffusers - nifty home fragrance devices that release essential oils mimicking nature-identical scents. With declining indoor and outdoor air quality, aroma diffusers have become personal and household essentials. Moreover, renewed interest in natural and holistic wellness practices has driven market growth, broadening applications from stress relief to sleep therapy. Contemporary smart diffusers feature app interfaces, setting controls, and other advanced functions to enhance the user experience.

A high-quality aroma diffuser displays both functionality and design. The use of engineering polymers like thermoplastic elastomers (TPE) provides the material properties needed to achieve the desired value.

KRAIBURG TPE, a global manufacturer of TPEs and customized solutions for various industries, offers the THERMOLAST® R series with optimized mechanical properties and recycled content as a key advantage, providing manufacturers with sustainable aroma diffusers material option that can reduce their products’ carbon footprint.
