DURAPONTEX^® eN35 Insole Provides Unmatched Cushioning and Rebound for High-Impact Sports

PORTLAND, Ore., March 28, 2025 /PRNewswire/ -- Dahsheng Chemical (DSC^®), a global leader in performance foam manufacturing, marks its 80th anniversary with the debut of its latest insole innovation: DURAPONTEX^® eN35. Utilizing DSC's advanced supercritical fluid foaming technique, the cutting-edge DURAPONTEX^® eN35 is engineered to withstand the demands of high-impact and jump-dominant sports while delivering ultra-lightweight performance. With the launch of DURAPONTEX^® eN35, DSC continues its 80-year legacy of innovation, pushing the boundaries of material science to redefine what's possible in athletic footwear.

Dahsheng Chemical celebrates 80th anniversary with the launch of DURAPONTEX® eN35, a revolutionary supercritical fluid foaming insole.

"We designed the DURAPONTEX^® eN35 for the athlete who demands high-energy return in a lightweight package," said Fennie Wei, COO of Dahsheng Chemical (DSC^®). "By leveraging our own proprietary DURAPONTEX^® N-Series supercritical fluid foaming technology and specialized formulation, the DURAPONTEX^® eN35 exhibits a significant advancement in lightweight technology. This new material offers powerful energy rebound, yet in an even lighter form, which the elite athlete craves."

DSC was the first brand to utilize supercritical fluid foaming technology in the development of an insole at scale with its DURAPONTEX^® N-Series. Supercritical fluid foaming has revolutionized performance footwear, offering superior energy return, lightweight comfort, and durability. Through rigorous testing and precision engineering, DSC has optimized its supercritical fluid foaming technique to deliver an insole that provides a balance of resilience, responsiveness, and comfort—setting a new benchmark in performance footwear. DSC's supercritical fluid foaming process has redefined what performance and support underfoot feels like, and is one of the most sought-after technologies for the elite athlete.

DURAPONTEX^® N-Series is DSC's specialized closed-cell foam compound, crafted with DSC's unique supercritical fluid foaming technology, infused with carbon dioxide (CO2) or nitrogen (N2). The sophisticated process requires consistent high temperature and pressure control. Carbon dioxide or nitrogen gas emissions are infused, leading to an innovative transformation. As a result, a soft foam cell is made with evenly spaced microscopic bubbles and air pockets, creating an ultra-lightweight insole that delivers unparalleled resiliency and responsiveness.

As part of the DURAPONTEX^® N-Series, DURAPONTEX^® eN35 is designed to deliver resiliency and rebound for high-impact and jump-dominant sports including basketball, volleyball, and tennis, among others. DURAPONTEX^® eN35 is ultra-lightweight with a low-density performance and 100% recyclable foam. The high-rebound insole is designed to adapt to a wide range of stresses without compromising its structural integrity and deliver consistent high energy return.

DSC's proprietary supercritical fluid foaming compound was tested, refined, and optimized last year through DSC's Athlete Engagement Program at the Portland Track Festival. Participants tried on the DURAPONTEX^® N-Series and DSC received positive feedback on the foam's lightweight comfort, durability, and powerful energy return. This valuable feedback drives DSC's commitment to continuous innovation, ensuring that every product meets the demands of high-performance athletes.

Since its founding in 1945, Dahsheng Chemical (DSC^®) has been a leader in foam innovation for the sports and bedding industries. Known for its premium comfort and performance foam DURAPONTEX^® and DREAMCELL^®, DSC partners with top brands and footwear manufacturers worldwide.
