Polyurethane foam is an essential component of many products on the market. From furniture upholstery to insulation, polyurethane foam is available in different forms with various functions. Whether you need spray polyurethane foam, flexible polyurethane foam or rigid polyurethane foam, a form exists to meet your unique needs.

If you are a distributor of polyurethane foam materials or need to use a type of polyurethane foam in your business, learn these important polyurethane foam key terms for a well-rounded knowledge of the material.

Spray polyurethane foam or SPF

Spray polyurethane foam, also called "SPF," is a type of polyurethane foam that is applied as a liquid and then it expands as a foam. This type of foam is used as an insulating material.

Flexible polyurethane foam

One of the most widely used forms of polyurethane foam, flexible polyurethane foam or "FPF" provides a flexible cushion in a variety of products. Furniture upholstery, carpeting and packaging materials are a sampling of the products that use flexible polyurethane foam
Try: Polyurethane.org offers extensive information on flexible polyurethane foam.

Rigid polyurethane foam

Rigid polyurethane foam is a type of foam that is durable, strong and energy efficient. Used as a form of insulation, rigid polyurethane foam can come in spray form or can be shaped to fit any need.
Try: The Polyurethane Foam Association offers more information on rigid polyurethane foam.

Microcellular polyurethane foam

Microcellular polyurethane foam is a high-density, energy-absorbing class of foam used to line protective helmets. This type of foam is also used to make steering wheels.

Elastomeric polyurethane foam

Elastomeric polyurethane foam is a closed-cell class of polyurethane foam that provides an excellent barrier against moisture. This type of foam is widely used in insulation and is also a material used in athletic shoes.
Try: Insulation.org provides more in-depth information on elastomeric polyurethane foam.

Viscoelastic or memory foam

Viscoelastic polyurethane foam, better known as "memory foam," is a high-density type of polyurethane foam that reacts to temperatures. Used in mattresses, pillows and chairs, viscoelastic foam is molded by pressure but returns to original shape once the pressure is removed.
