HD Foam typically refers to High-Density Foam, which can be made from PU, PE, or other polymers. It offers superior strength and load-bearing capacity.
EPE (Expanded Polyethylene) Foam is a lightweight, flexible material with excellent shock absorption. Common in packaging for electronics, medical devices, and fragile goods.
HDPE (High-Density Polyethylene) Foam is a rigid, durable foam resistant to chemicals and UV radiation. Used in automotive panels, marine structures, and industrial packaging.
Closed-cell PU foam is waterproof and used for flotation devices or insulation. Open-cell PU foam is breathable and absorbs moisture, ideal for cushioning.
PU stands for Polyurethane Foam, a versatile material available in flexible, rigid, or sprayable forms.
Specialty foams are high-performance foams designed for extreme environments. Examples include:
- Silicone Foam: Heat-resistant (up to 300°C), used in aerospace.
- Fluoropolymer Foam: Chemically inert for corrosive settings.
- Aerogel Foam: Ultra-lightweight with superior insulation.
Applications span industries such as:
- Automotive: Seats, dashboards, and noise reduction.
- Construction: Insulation panels, sealants.
- Packaging: Protective inserts, anti-static trays.
- Marine: Buoyancy aids, flotation devices.
- HVAC: Thermal and acoustic insulation.
- Electronics: Vibration damping, EMI shielding.
Major types include:
- Polyurethane (PU) Foam: Flexible or rigid, used for insulation, seating, and packaging.
- Polyethylene (PE) Foam: Lightweight and moisture-resistant (e.g., HDPE, LDPE).
- Expanded Polyethylene (EPE) Foam: Shock-absorbing, used in protective packaging.
- Polystyrene (PS) Foam: Includes EPS (expanded) and XPS (extruded) for insulation.
- Melamine Foam: Fire-resistant and sound-absorbing.
- Specialty Foams: Silicone, fluoropolymer, or aerogel-based for extreme conditions.
Industrial foams are lightweight, cellular materials created by trapping gas bubbles in a solid or liquid matrix. They are engineered for specific properties like insulation, cushioning, buoyancy, or structural support. Common materials include polyurethane (PU), polyethylene (PE), polystyrene (PS), and specialty polymers.
