Soft, springy piSpring® mattress topper with Desmodur® white
The new piSpring® aliphatic foam mattress topper from Holyfoam unites softness, high elasticity, and high sleep comfort. This ‘360-degree dynamic micro force feedback’ is enabled by the Desmodur® white hardener. The piSpring® aliphatic foam product is now used by several major global bedding brands.
Holyfoam, a manufacturer of flexible polyurethane (PU) foams known for its success in the appliance & lingerie industry, has expanded its product range to include a mattress topper. Mattress makers are on a permanent quest to increase sleeping comfort by balancing body pressure release and rebound support in their mattresses, along with haptic performance and breathability to assure a good night’s rest. Holyfoam turned to us when they needed a material solution for their new piSpring® mattress toppers.
When it comes to mattresses, polyurethane foams often mean a compromise between two aspects of comfort. The softer or more viscoelastic the PU foam, the less rebound performance it tends to offer. In contrast, PU foams with high elasticity and recovery often mean a harder surface feel. A new material was needed that could solve this core dilemma while also ensuring a hygienic, colorfast product that resists yellowing.
Our Desmodur® white hardener creates a new category of aliphatic PU foams that combine softness and elastic rebound in the piSpring® mattress topper, labelled ‘360-degree dynamic micro force feedback’. Flexible molecular chains in the foam are matched with highly crosslinked segments that allow the molecules to quickly regain their original position in the foam structure. This enables PU foams that are soft and flexible at the same time, with attractive colorfastness for the bedding industry.
Covestro’s Desmodur® white product enabled our piSpring® mattress topper with unique properties of softness and resilience, delivering ‘360-degree dynamic micro resilience’ that provide excellent user experiences on pressure relief and calm sleep.
