Product details

Polyurethane foam for cushioning, gap filling, sealing and protection.

Polyurethane foam material application PU Foam

PU foam is soft, elastic and highly effective for cushioning. It is suitable for shock absorption, gap filling, sealing and protection in electronic products, home appliances, instruments and general industrial products.

Typical applications

  • Electronics: internal cushioning pads for phones, tablets and laptops, battery compartment gap filling, and display frame sealing.
  • Home appliances: panel vibration damping, internal component fixing and door-seal gap filling.
  • Instruments: shock protection for precision components and housing sealing.
  • General industry: equipment foot cushioning, enclosure gap filling and transport packaging protection.

Available formats

  • Sheets and rolls
  • Die-cut parts
  • Adhesive backing
  • Slitting and rewinding
  • Splicing and thickness stacking

Optional properties

  • Density and hardness adjustable by requirement
  • Flame-retardant, conductive or thermal-conductive modification
  • Single-sided or double-sided adhesive
  • Can be laminated with PET, release film and other materials

Microcellular polyurethane

Rogers PORON® Foam

Rogers PORON polyurethane foam is a material family for cushioning, gasketing and vibration control. For compact assemblies, selection starts with the gap to be filled and the force the components can tolerate when the foam is compressed.

Model reference
Our directory includes PORON 4701 and 4790 series, along with thin ShockPad references. Use the complete part number to identify a candidate material.
Typical uses
Electronic housings, component cushioning, die-cut pads and contact gaskets.
Selection focus
Review thickness, compression force and compression set for the specific grade; validate the assembled part under its operating conditions.

Cushioning and recovery options

INOAC Polyurethane Foam

INOAC foam provides a range of cushioning responses for applications that need flexible contact between parts. Our PU foam directory groups INOAC models by their listed characteristics so you can begin with the required softness, support or recovery behavior.

Model reference
L-24 / L-32, H-24 / H-32 / H-48, HH-48 / HH-48C, FH-48C, LE-20, ML, MS and SR-S models are included in the reference table.
Typical uses
Gap-filling pads, equipment cushioning, protective liners and converted contact parts.
Selection focus
Compare hardness and recovery behavior against the assembly load. Confirm thickness and grade-specific properties before final selection.
