Polyurethane Foam
Polyurethane foam, also known as PUR foam, is a versatile synthetic foam produced through the reaction of polyols and isocyanates. It is characterised by outstanding insulating properties, flexibility, and durability. Polyurethane foam is widely used across various industrial and everyday applications, including construction, furniture manufacturing, automotive, and packaging.
Physical and Chemical Properties
Polyurethane foam exhibits several notable properties:
-
Insulating properties: Excellent thermal and acoustic insulation.
-
Flexibility: Ranges from soft and flexible to rigid, depending on manufacturing.
-
Durability: Long‑lasting and resistant to wear and mechanical stress.
-
Light weight: Easy to transport and handle.
-
Chemical resistance: Withstands many chemicals and solvents.
Uses of Polyurethane Foam
Thanks to its unique properties, polyurethane foam is applied in many areas:
-
Construction: Used for insulation in walls, roofs, and floors due to its high thermal performance.
-
Furniture industry: Employed in upholstered furniture, mattresses, and cushions for its comfort and flexibility.
-
Automotive: Used in seat cushions, dashboards, and interior trim for its formability and durability.
