Polyethylene (PE) Foam
Polyethylene (PE) foam is a strong, resilient, closed-cell foam known for its excellent shock absorption and vibration-damping properties. It’s lightweight, non-abrasive, and resistant to moisture and chemicals, making it a versatile choice for protecting a wide range of products, from delicate electronics to industrial components. PE foam is also available in various densities and colors to meet specific packaging needs.
📦 Key Features of PE Foam:
- Excellent shock and vibration absorption
- Lightweight yet durable
- Moisture and chemical resistant
- Non-abrasive surface
- Available in various densities and colors
Polyurethane (PU) Foam
Polyurethane (PU) foam is a versatile open-cell foam known for its cushioning and conformability. It offers good shock absorption and is often used for lighter-weight items or applications where a snug fit is important. PU foam is available in different densities and can be easily cut and shaped to create intricate custom inserts.
📦 Key Features of PU Foam:
- Good cushioning properties
- Conforms well to product shapes
- Lightweight and flexible
- Cost-effective option for many applications
- Available in various densities
Memory Foam
Memory foam, also known as viscoelastic foam, is a unique polyurethane foam that conforms to the shape of the object it supports and slowly returns to its original form. This makes it ideal for protecting delicate and irregularly shaped items by providing a highly customized and secure fit. It’s excellent shock absorption also makes it suitable for sensitive electronics and medical devices.
📦 Key Features of Memory Foam:
- Exceptional contouring and support
- Excellent shock absorption
- Provides a highly customized fit
- Ideal for delicate and irregularly shaped items
Expanded Polystyrene (EPS) Foam (Styrofoam)
Expanded Polystyrene (EPS), known as Styrofoam, is a rigid, lightweight, and cost-effective closed-cell foam with excellent insulation and cushioning properties. It’s often used for packaging fragile items and temperature-sensitive products. EPS can be molded into specific shapes to provide precise protection.
📦 Key Features of EPS Foam:
- Excellent cushioning and insulation
- Lightweight and rigid
- Cost-effective for many applications
- Moldable into custom shapes
Cross-Linked (PE) Foam
Cross-linked polyethylene (XLPE) foam is a closed-cell foam with enhanced properties compared to standard PE foam. The cross-linking process creates a foam with a smoother surface, increased tear strength, and improved dimensional stability. It offers excellent protection and is often used for higher-value items or applications requiring a more refined aesthetic.
📦 Key Features of XLPE Foam:
- Smoother surface finish
- Increased tear strength and durability
- Improved dimensional stability
- Excellent shock and vibration absorption
- Chemically inert and water-resistant
