Weinheim, Germany, October 26, 2023. Freudenberg Performance Materials Apparel (Freudenberg), a leading provider of innovative technical solutions in the apparel industry, is pleased to launch two advanced thermal insulation products made from low-level Bisphenol A (BPA) recycled PET fibers (rPET) into the global range of comfortemp®, Freudenberg’s thermal insulation brand. The introduction of DOWN FEEL WA 150LB and FIBERBALL WB 400LB underscores Freudenberg’s commitment to innovation and sustainability.

The additions of DOWN FEEL WA 150LB and FIBERBALL WB 400LB to the comfortemp® global range serve as high-quality and ecologically-minded alternatives to down, enhancing the comfort and sustainability of your garments. DOWN FEEL WA 150LB is an extremely-lightweight, loose fiber thermal insulation with a super-light loft, while FIBERBALL WB 400LB uses clusters of extra-fine fibers to offer optimal breathability, maximum comfort, and minimal clumping after washing and drying.

GRS-certified and OEKO-TEX® STANDARD 100 Class I certifications

Both products are crafted using Freudenberg’s advanced technology, utilizing 100% GRS-certified rPET fibers, customizable to your desired fill levels. Additionally, these new products not only comply with but significantly surpass the stringent OEKO-TEX® STANDARD 100 Class I certifications (the strictest requirements, suitable for babies). While OEKO-TEX® categorizes low-level BPA as less than 100 parts per million (ppm), these new products contain less than 1 ppm BPA, a testament to Freudenberg’s unyielding standards.

“Our commitment to customers and sustainability aligns with market expectations for safer, responsible products while maintaining quality and performance,” said Merry Chen, Head of Global R&D and Product Compliance, Freudenberg Performance Materials Apparel. “The DOWN FEEL WA 150LB and FIBERBALL WB 400LB products exemplify this commitment, providing innovative thermal insulation that prioritizes performance and customer well-being as we grow our House of Sustainability.”
