Cross-Linked Polyethylene (XLPE) Foam
Fine cell structure, exceptional cut quality, chemical resistance, and moisture impermeability - XLPE is the premium closed-cell foam for medical, aerospace, cleanroom, and high-specification industrial packaging where standard PE won't meet the requirement.
Properties
Key physical and performance characteristics of this foam grade.
Density Options
Choose the right density based on product weight, fragility, and retention requirements.
| Density | Firmness | Best For |
|---|---|---|
| 2.0 lb/ft³ | Medium | Light instruments, cleanroom trays |
| 4.0 lb/ft³ | Firm | Most medical and aerospace applications |
| 6.0 lb/ft³ | Very Firm | High-precision retention, heavy components |
When to Use It
Industries and use cases where this foam type performs best.
Medical Devices & Instruments
Sterile and non-sterile packaging where chemical resistance and cleanliness are required.
Aerospace Components
Precision parts requiring tight tolerances and resistance to aerospace fluids.
Cleanroom Packaging
Semiconductor, optics, and pharmaceutical components in controlled environments.
Defense & Mil-Spec
MIL-spec packaging calling for chemical-resistant foam with precise cut tolerances.
Marine & Outdoor Equipment
XLPE's moisture impermeability makes it ideal for equipment exposed to water.
High-Precision Optics
Lens, mirror, and optical assembly packaging requiring zero particulate contamination.
How APG Works With Cross-Linked Polyethylene (XLPE) Foam
XLPE is specified when standard PE doesn't meet chemical resistance, cleanliness, or cut tolerance requirements. The premium cost is justified in medical, aerospace, and cleanroom applications where the foam quality directly affects product integrity and compliance.
