Description

PORON® 4701-40V0 polyurethane foam is a high-performance elastomeric solution engineered to provide reliable sealing, cushioning, and vibration management in demanding industrial applications. Designed with a fine microcellular structure, this foam combines softness with durability, offering consistent mechanical properties across a wide range of operating conditions. It delivers excellent compression set resistance, ensuring long-lasting performance even under repeated stress, while its stable dimensional integrity makes it a dependable choice for precision applications.

With a density of 176 kg/m³ (11 lb/ft³), PORON® 4701-40V0 offers a Shore OO hardness of 32, providing both resilience and comfort in sealing and gasketing environments. Its flammability rating meets UL94 V-0, FMVSS 302, and CSA Comp V0 standards, making it an ideal choice for applications requiring flame-retardant materials. The foam also exhibits low outgassing, high electrical resistivity, and thermal stability, with recommended continuous use up to 90°C (194°F) and intermittent resistance up to 121°C (250°F). Tested for tensile strength, tear resistance, and elongation, PORON® 4701-40V0 stands out for its balance of flexibility and toughness.

Whether used in electronics, transportation, or industrial equipment, PORON® 4701-40V0 delivers reliable sealing and protection with enhanced safety and material integrity. Its superior resistance to compression and environmental factors makes it a trusted choice for manufacturers seeking long-term durability and compliance with stringent flammability requirements.
