ESD Box Foam Cushions
Precision-cut conductive and antistatic foam cushions for ESD protective boxes and SafePak™ packaging systems. Available in open-cell and closed-cell foam materials, these flat cushions help support static-sensitive electronic components, integrated circuits, semiconductor devices, and precision assemblies during storage, handling, and transport.
ESD Box Foam Cushions for Static-Sensitive Electronics
ESD box foam cushions provide cushioning, component retention, and electrostatic protection for static-sensitive electronics stored or transported in ESD protective boxes and SafePak™ packaging systems. Malaster supplies precision-cut conductive and antistatic foam inserts selected to help reduce movement and physical damage during handling, storage, and shipment.
Standard cushions are available in five footprints for Malaster ESD box series. CFS and CFF conductive cushions are 0.22 inch nominal; AFD and AFDF antistatic cushions are 0.25 inch thick. CFS and CFF are skived foams with thickness variation, so specify any required thickness limits with Malaster. Select the material and thickness together with the component height, permitted contact areas, and complete closed-box arrangement.
Available Foam Materials
- Soft Conductive Open-Cell Urethane Foam (CFS) – Soft conductive cushioning for sensitive electronic components and assemblies.
- Firm Conductive Closed-Cell Cross-Linked Polyethylene Foam (CFF) – Firm conductive foam for a more structured support layer.
- Soft Antistatic Open-Cell Polyether Polyurethane Foam (AFD) – Soft pink foam that helps reduce static charge generation while providing cushioning.
- Firm Antistatic Closed-Cell Low-Density Polyethylene Foam (AFDF) – Firm, lightweight pink polyethylene foam for cushioning and support.
Common Applications
- Integrated circuit packaging and shipping
- Semiconductor device storage and handling
- Precision electronic component protection
- Military and aerospace electronics packaging
- Medical device and instrumentation packaging
- ESD-safe inventory and warehouse storage
- Custom component kitting and organization

Why Choose Malaster ESD Box Foam Cushions?
Malaster ESD Box Foam Cushions are designed to provide reliable cushioning and electrostatic protection for sensitive electronic components during storage, handling, and transportation. Available in both conductive and antistatic materials, these precision-cut foam inserts help minimize movement, absorb shock and vibration, and support ESD control requirements throughout manufacturing and shipping operations.
- Conductive & Antistatic Options – Available in conductive and antistatic materials to support a variety of ESD control programs and packaging requirements.
- Open-Cell & Closed-Cell Foams – Choose from resilient polyurethane foams or durable polyethylene foams depending on cushioning and cleanliness requirements.
- Shock & Vibration Protection – Helps reduce component movement and absorbs impacts during storage, handling, and transit.
- Precision-Cut Dimensions – Manufactured to fit popular ESD protective box footprints for consistent and reliable component protection.
- Application-Specific Material Selection – Review component contact, cleanliness requirements, compression, and available material documentation for the intended application.
- Multiple Standard Sizes – Offered in five standard footprints, with thickness depending on the foam family. Confirm usable space inside the closed box rather than selecting by footprint alone.
- Compatible with SafePak™ Systems – Designed for use with Malaster ESD protective boxes and complete SafePak™ protection kits.
- Custom Converting Available – Additional thicknesses, materials, die-cut shapes, and custom dimensions are available upon request.
Each standard product supplies one individual flat cushion. Boxes, additional cushions, and device inserts are separate selections. Foam properties alone do not establish a finished-package shielding rating. For help comparing materials, read our antistatic and conductive foam guide.
