HRschuim

HRschuim, often written as high-resilience foam, is a category of flexible polyurethane foam used primarily in cushioning applications. The term is common in Dutch- and German-speaking contexts and denotes foams designed to combine high elasticity with durable shape recovery. Compared with standard PU foams, HRschuim offers faster resilience, better load transfer, and improved long-term durability under repeated compression.

Manufacturing and composition rely on the standard polyurethane process. HR foams are produced by reacting specific polyols with diisocyanates (typically MDI or PMDI) in the presence of catalysts, surfactants, and blowing agents. The formulation and cell structure are adjusted to achieve a balance of density, hardness, and elasticity that yields rapid recovery after deformation. Additives such as flame retardants and colorants may be included to meet safety and product requirements. The choice of blowing agent and process conditions influences environmental footprint and aging behavior.

Properties of HRschuim include high resilience (energy return), good support, and resistance to permanent indentation. These foams are valued for comfort and durability in seating and bedding applications, where repeated loading is common. Densities vary with intended use, but HR foams are typically chosen to optimize both feel and structural integrity over time. They may be formulated to meet relevant fire-safety standards and regulations.

Applications span upholstered furniture, mattresses, automotive seating, and office chairs. In addition to performance, considerations include lifecycle impact, recycling options for polyurethane foams, and compliance with regional fire and environmental regulations. HRschuim remains a standard option where durable, responsive cushioning is required.
