Different Types of Polyurethane Foam
Type of Foam | Characteristics | Applications |
Flexible Foam | Soft, flexible, low-density foam. | Upholstery, mattresses, packaging, automotive seat cushions. |
Rigid Foam | High-density, sturdy, excellent insulation. | Insulation in buildings, refrigeration units, pipe insulation, automotive parts. |
Semi-Rigid Foam | Offers a balance between flexibility and rigidity. | Insulation in automotive parts, gaskets, seals. |
Spray Foam |
Applied as a liquid, expands into foam. |
Building insulation, roofing, air-sealing. |
High Resilience Foam | High elasticity, quick recovery. | High-end mattresses, seat cushions, medical cushions. |
How to Choose Polyurethane Foam for Different Needs?
-
Density: affects the strength and durability of the foam. Higher-density foams are more rigid and durable, making them suitable for insulation or structural applications, while lower-density foams are better for cushioning or flexible uses.
-
Flexibility: defines the ability of the foam to bear pressure and regain its shape. Conventional flexible foams have relatively high elasticity and are suitable for cushioning applications such as furniture and automobile seats.
-
Thermal Insulation Properties: Especially important for uses where it is necessary to save energy, for example in construction, insulation, or refrigeration equipment. Low thermal conductivity rigid foam is suitable for these uses.
-
Acoustic Performance: Of particular relevance to soundproofing functions. The foams with small and closely packed cells have good sound absorption characteristics and are therefore suitable for use in walls, floors, and other sound-vulnerable applications.
-
Customization Requirements: There are also some applications where foam will have specific surface treatment (e.g., fire-resistant or water-proof). One should then ask whether these additional features are needed depending on the conditions where the foam is going to be used.
