There are many different types of polyurethane flexible foams on the market, following are a few popular varieties types for your reference:
Polyether Foam: Polyether polyols, which are produced from ethylene oxide, are used to make polyether foam. High flexibility, robustness, and great hydrolysis resistance are typical characteristics of this kind of foam. It is frequently used in bedding, car seating, and furniture cushions.
Polyester Foam: Polyester polyols are used to make polyester foam. It can be a more affordable alternative for a variety of cushioning and insulating applications because it often has a little higher density than polyether foam.
Foam with high resilience (HR): A particular variety of polyurethane foam called HR foam was made with high resilience or “bounce-back” properties in mind. It is perfect for use in upscale seating and furniture applications where support and comfort are essential.
Memory Foam: Also called viscoelastic foam, memory foam is a form of polyurethane foam with added chemicals that react to pressure and body heat. As a result, the foam takes on the contour of the user, offering excellent pressure relief and relaxation. Medicinal cushions, pillows, and mattresses frequently contain memory foam.
Combination foam: To obtain particular performance characteristics, combination foam combines various polyurethane foam kinds, such as polyether and polyester. This enables manufacturers to modify the characteristics of foam to satisfy particular needs.
HR Visco foam: High-resilience and memory foam are combined in HR Visco foam. It is suitable for high-end seating and bedding goods because it combines the rebounding qualities of HR foam with the contouring qualities of memory foam.
Conventional Foam: Conventional polyurethane foam is the most widely used and accepted type of flexible foam, providing a good combination of comfort and support. It is used in many different things, like packing materials and furniture cushions.
Super Soft Foam: Super Soft Foam is a low-density, extremely soft form of polyurethane foam. It is utilized in applications that call for more comfort and cushioning, like upholstered furniture and bedding toppers.
Filter Foam: Due to its high permeability and capacity to trap particles, filter foam is an open-cell polyurethane foam that is predominantly utilized in air and water filtration systems.
Keep in mind that the particular names and compositions of different foam kinds vary depending on the manufacturer. To choose the proper kind of foam for your intended application, you should always speak with foam suppliers or manufacturers.
