Rogers Foam

Introduction to Rogers Foam and Poron Foam

The core of Rogers foam is the Poron® series (microcellular polyurethane PU foam), a registered trademark of Rogers Corporation and the benchmark for engineered foam; other elastomer materials include BISCO® silicone foam. Poron is renowned for its minimal compression set, high resilience, and superior sealing/energy absorption properties. It is extensively used in sealing, cushioning, and shielding applications across electronics, automotive, and industrial sectors, particularly suited for precision die-cutting and EMI shielding composite solutions.

Core Technical Characteristics of Poron Foam (Distinguishing It from Ordinary Foam)

1. Mechanical Properties (Core Advantages)

Ultra-low permanent compression set: Exceptionally high shape retention after prolonged compression (typically < 5%)

Superior resilience: Rapid recovery with minimal performance degradation after repeated compression cycles

Outstanding energy absorption: Efficient dispersion of impact energy

Controllable density: Selectable range of 144–480 kg/m³ to accommodate varying strength requirements

2. Environmental Adaptability

Wide Temperature Stability: Operating range -40°C to 120°C

Low Outgassing & Anti-Fogging: Minimal volatile emissions, suitable for enclosed spaces

Anti-Aging & Chemical Resistance: Resistant to ozone and hydrolysis; no brittleness or cracking during prolonged use

Halogen-Free Flame Retardancy (select grades): Meets UL94 V-0 and other safety standards

3. Processing and Application Characteristics

Ideal for Die-Cutting: Precisely die-cut into any shape (gaskets, liners, sealing strips) with smooth edges and tight tolerances (±0.05mm)

Easy bonding: Excellent surface wettability allows lamination with adhesive tapes (e.g., 3M, Nitto), compatible with automated application

Superior sealing performance: Achieves waterproof sealing even with perforated structures, suitable for IP protection designs

Functional lamination: Can be combined with conductive layers (copper/nickel plating) or thermal materials to integrate “shielding + thermal management + sealing + cushioning” functions
