Types of Polyurethane Foam Box Liners
1. Open-Cell Foam
Open-cell foam is characterized by its porous structure, allowing air and moisture to pass through. This type of foam is ideal for applications requiring sound absorption and cushioning, making it suitable for electronics packaging and protective inserts.
2. Closed-Cell Foam
Closed-cell foam features tightly packed cells that do not allow air or moisture to pass through. This makes it excellent for thermal insulation and waterproofing applications. Industries that benefit from closed-cell foam include marine, automotive, and construction.
3. Rebonded Foam
Rebonded foam is made from scraps of foam that are bonded together, resulting in a cost-effective and environmentally friendly product. It is commonly used for upholstery and cushioning, offering decent durability at a lower price point.
4. Memory Foam
Memory foam is a type of viscoelastic foam that conforms to the shape of an object when pressure is applied. This unique property makes it popular for bedding and cushioning applications, providing comfort and support.
5. High-Density Foam
High-density foam offers superior support and durability, making it suitable for industrial packaging and protective cases. This type of foam can withstand heavy loads and is often used in military and aerospace applications.
