poron

Poron is the trade name for a family of closed-cell polyurethane foams produced for a variety of cushioning, sealing, and vibration-damping applications. The material is valued for its resilience, lightweight feel, and durable performance across a range of temperatures and environments. A well-known variant in the Poron family is Poron XRD, a high-performance urethane foam optimized for impact protection and comfort in sports equipment, footwear, and protective gear.

Poron foams are closed-cell structures, which makes them resistant to water absorption and many chemicals. They typically maintain their shape and cushioning under repeated loading and offer good energy absorption and rebound. The foams are generally lightweight, can be cut or die-cut to shape, and are available in multiple densities and hardness levels to suit different applications. They can be fabricated as sheets, blocks, or molded components and are often bonded to fabrics, plastics, or metal surfaces through adhesives or lamination.

Common applications include footwear insoles and pads, protective padding for sports equipment, vibration and shock damping in electronics and automotive components, acoustic and thermal insulation, and various gasket and seal implementations in consumer and industrial products. Poron materials are chosen for their combination of cushioning, moisture resistance, and dimensional stability, along with their ability to be machined into complex shapes.

Limitations may include sensitivity to certain solvents and prolonged exposure to high temperatures, which can affect performance over time. Poron foams are not biodegradable and are typically considered a synthetic material used in engineered applications where durable cushioning and sealing are needed.
