Polyethylene Foam

Polyethylene foam is a high-performance, closed-cell foam material distinguished by its robust durability, resilience, and anti-static properties. This premium material is engineered to meet a broad range of packaging needs, especially where static sensitivity and impact resistance are paramount. With exceptional shock absorption and anti-static capabilities, polyethylene foam provides unmatched protection for sensitive electronic devices and delicate components, ensuring secure transport and long-term storage.

Basic Parameters

The key technical specifications of polyethylene foam are as follows:

Special Properties

• Structural Integrity and Impact Resistance

Polyethylene foam's closed-cell structure offers outstanding impact resistance, effectively absorbing shocks and vibrations during transportation or handling. This cellular configuration prevents air, moisture, and contaminants from penetrating, ensuring long-lasting resilience. The foam's firmness and flexibility allow it to withstand intense pressures without breaking or fragmenting, providing consistent protection for sensitive items over extended periods.

• Anti-Static Properties

Specialized anti-static variants of polyethylene foam, such as the pink 1.7 lb density option, are chemically formulated to dissipate electrostatic discharge (ESD) effectively. This formulation safeguards electronic components from static-related damage by neutralizing static charges upon contact. Featuring a surface resistivity range of 1.00 x 105 to 1.00 x 1012 ohms (EIA 541 compliant), this foam maintains an optimal balance between conductivity and insulation. Additionally, the static decay rate of under 2.0 seconds (EIA 541 standard) ensures rapid charge dissipation, further protecting valuable electronics from potential ESD risks.

• Enhanced Protection for Sensitive Components

With its high resistance to mold, mildew, bacteria, and chemicals, polyethylene foam excels in applications requiring rigorous contamination control. This makes it ideal for industries needing sterile packaging solutions, such as medical devices and electronic components. Its oil and grease resistance provides additional security for products vulnerable to environmental contamination.

• High Buoyancy and Chemical Resistance

Due to its superior buoyancy, polyethylene foam serves effectively in flotation devices and marine applications. Its chemical resistance further adds to its versatility, making it compatible with products exposed to solvents, fuels, and oils, while maintaining integrity and functionality under extreme conditions.

Application Guidelines

When choosing polyethylene foam for packaging, consider the weight and fragility of the item. For heavier or sharper objects, harder polyethylene foam offers enhanced protection. In contrast, lightweight and smaller items benefit from softer anti-static foam layers. The correct thickness and density selection are essential in creating an effective, custom-fit barrier against static discharge and mechanical impact. The foam is also compatible with egg crate-style patterns, enhancing structural support and professional presentation.
