Slow Rebound PORON 4790-92 Series Extremely Soft Foam Material

• Ultra Soft Cushioning - Extremely low stiffness for applications that require a comfortable fit (e.g. headphone ear cushions, wearable devices).
• Energy Absorption - Effectively disperses impacts and protects delicate components (e.g. cell phone/tablet shock pads).
• Long-term stability - Resist permanent deformation, long service life (better than ordinary EVA or memory foam).
• Customized Processing - Can be die-cut, stamped, and back-glued to suit different structural needs.

Consumer Electronics

• Headphone/earbud cushion (enhances wearing comfort)
• Smartphone/tablet cushioning (reduce drop impact)
• Smartwatch/bracelet cushioning (conforms to skin and resists perspiration)

Medical & Rehabilitation

• Orthopedic shoe cushions (cushioning and pressure reduction)
• Wheelchair cushions (reduce long-term compression)
• Medical sensor cushioning (improves fit)

Automotive & Industrial

• Automotive seat comfort layer (reduces long distance fatigue)
• Precision instrument shock pads (anti-vibration shock)
• Battery cushion isolation sheet (prevents extrusion short circuit)

PORON 4790-92 Processing and Customization Options

• Die-cutting - Precision cutting into complex shapes (e.g., shaped seals).
• Adhesive Backing - Acrylic or silicone adhesive systems are available to enhance adhesion.
• Composite lamination - can be combined with non-woven fabrics, PET films, etc. to enhance structural strength.

Frequently Asked Questions (FAQ)

Is PORON 4790-92 suitable for high temperature environment?

• No. It is suitable for long-term use up to 70°C, and can withstand 100°C for short-term use (e.g., short exposure during reflow soldering).

What are the advantages of PORON over memory foam?

• PORON has lower compression set, longer life, and is less prone to moisture absorption, making it suitable for precision electronics and medical applications.

Are there any environmental certifications?

• RoHS and REACH compliant, and some models support bio-based materials (customized).
