Packaging

1. Protective Packaging:Safeguards fragile items like electronics, appliances, and furniture during shipping.
2. Food Packaging: Used in disposable containers, coffee cups, and coolers for perishables (though some regions restrict this due to environmental concerns).
3. Medical Packaging: Protects sensitive equipment and pharmaceuticals during transport.

Construction

1. Insulation: Provides thermal efficiency in walls, roofs, and floors via panels or blocks.
2. Structural Applications: Lightweight fill in roads (geofoam) and insulated concrete forms (ICFs) for foundations.
3. Decorative Elements: Moldings, ceiling tiles, and architectural features.

Automotive

1. Impact Protection: Bumpers and child safety seats.
2. Noise Reduction: Sound insulation in doors and dashboards.
3. Lightweight Components: Reduces vehicle weight for improved fuel efficiency.

1. Sculptures/Props: Easily carved for stage sets, parade floats, or model-making.
2. Floral Arrangements: Stabilizes artificial plants in displays.

Sports and Recreation

1. Buoyancy Aids: Life jackets, surfboards, and dock floats.
2. Protective Gear: Padding in helmets and sports equipment.
3. Coolers: Insulated containers for camping or picnics.

Medical

1. Orthotics/Prosthetics: Lightweight, customizable components.
2. Temperature-Sensitive Transport: Containers for organs, vaccines, or medical samples.

Geotechnical Engineering

1. Lightweight Fill: Reduces soil pressure in road/railway construction on unstable ground.
2. Drainage Systems: Used in landscaping and erosion control.

Agriculture

1. Greenhouse Insulation: Maintains temperature for plant growth.
2. Hydroponics/Nursery Trays: Lightweight growing mediums.

Disposable Products

1. Single-Use Containers: Plates, trays, and ice chests (phased out in some areas).
2. Cooler Boxes: Temporary storage for food/medical supplies.

Marine Industry
