MC-4AFDF 4.25-inch Firm Wafer Cushion Foam Disc

Detailed Product Description

The Firm Wafer Cushion MC-4AFDF is a 4.25-inch diameter, 0.25-inch thick closed-cell antistatic foam disc designed to help protect semiconductor wafers and other delicate substrates during storage, handling, and transportation. Manufactured from resilient antistatic closed-cell polyethylene foam, this wafer cushion provides reliable ESD-safe support while helping reduce the risk of abrasion, vibration transfer, and handling damage within horizontal wafer packaging systems.

Its firm closed-cell construction provides greater dimensional stability and reduced compression compared with softer open-cell cushioning materials, making it well suited for wafer packaging applications requiring additional support and controlled spacing. The antistatic material formulation helps dissipate electrostatic charges that could damage sensitive semiconductor devices and electronic components.

The Firm Wafer Cushion MC-4AFDF is suitable for contamination-sensitive environments where clean handling, structural consistency, and ESD protection are important throughout storage and transportation processes.

Practical Applications

The Firm Wafer Cushion MC-4AFDF is designed for use throughout semiconductor packaging and wafer handling operations.

• Provides ESD-safe support and cushioning for semiconductor wafers during storage and transport.
• Helps reduce scratching, abrasion, vibration transfer, and handling damage to delicate wafer surfaces.
• Suitable for wafer jars, wafer shippers, wafer carriers, and horizontal wafer packaging systems.
• Supports contamination-conscious semiconductor and cleanroom packaging applications.
