Overview

ALS Tape supplies Rogers PORON microcellular urethane foam for industrial gasketing, sealing, cushioning, and vibration management applications. PORON is an engineered polyurethane material built for durable long-term compression performance — it resists compression set far better than conventional foams, which means gaskets and seals maintain their sealing force over the product lifetime without permanent deformation. The material contains no plasticizers and no residual chemicals that outgas, fog, or corrode metal contact surfaces, making it suitable for optical, electronic, and precision equipment enclosures. Inherent flame retardancy (without additives) meets UL HBF and MVSS 302 standards. The wide modulus range (2–90 psi at 25% deflection) and available thickness from 0.012" to 0.500" (0.43 mm to 12.7 mm) support a broad range of design requirements. PORON die-cuts cleanly and works with a broad range of adhesive systems.

Key Features

Excellent Compression Set Resistance — Maintains sealing force and gasket geometry over long service life without permanent deformation. Critical for enclosures, connectors, and assemblies that must seal reliably over years.

Low-Outgassing, Non-Fogging, Non-Corrosive — Contains no plasticizers or residual chemicals. Will not fog optical surfaces, contaminate electronic devices, or corrode metal contact areas.

Inherent Flame Retardancy — Meets UL HBF and MVSS 302 fire standards without the use of flame-retardant additives, avoiding contamination concerns common in additive-treated foams.

Wide Modulus Range (2–90 psi @ 25% deflection) — Engineered urethane formulations span from very soft to firmer grades, supporting cushioning-critical and sealing-critical designs within the same material family.

Thickness Range 0.012" to 0.500" (0.43 mm to 12.7 mm) — Available across a broad thickness range to match compression gap and housing geometry in tight-tolerance assemblies.

Die-Cuts Cleanly — Compatible with precision die-cutting, works with a broad range of adhesive bonding systems, and supports laminated adhesive constructions for direct assembly use.
