The foam we use in our cushions, mattresses, and furniture is more than just something that looks good. It’s also a tool that provides support and comfort as well as durability. Nowadays, there are many different types of foam out there that can be used in various applications because each one has its own benefits and drawbacks depending on the application. Here are some types of foam you may want to consider for your next project:

Polyurethane Foam

Polyurethane foam is a plastic foam that has been used in a variety of applications. It is commonly used in furniture, mattresses and packaging. Polyurethane foam can also be found in insulation and the automotive industry.

Polyurethane foams are typically made from polyols and organic blowing agents like methylene chloride or trichlorofluoromethane. These ingredients are mixed together in a liquid phase, which then react to form the foam. The mixture is poured into an open mold at room temperature and then allowed to expand until it fills the mold completely before hardening into its final shape once it cools down again after being removed from its mold.

Polyethylene Foam

Polyethylene foam is used in packaging, insulation and cushioning. It’s a low cost, low density foam that can be cut to whatever shape you need.

  • Polyethylene foam is not recommended for outdoor use because it’s not waterproof.
  • Polyethylene foam has a high R-value (insulation rating), so it’s good for cold weather applications like refrigeration units or ice chests where it needs to keep food cold for an extended period of time.

Polystyrene Foam

Polystyrene foam is a type of expanded polystyrene that’s used as a material in a variety of products and applications because of its lightweight, strong, and insulating nature. When manufactured into blocks or sheets, it can be used for packaging applications; when melted down into beads, it can be used for thermal insulation purposes. Polystyrene foam is also commonly used in construction projects like walls or floors to add strength and thermal resistance to structures.

EVA Foam

EVA foam is a closed-cell foam, meaning it’s made of polyols and other chemicals that are reacted with each other under heat and pressure to create a solid. It forms into a skin on the top that’s impermeable to air, water, dust and other small particles. This is why EVA foams are so popular in shoe soles: they’re very light weight yet resilient enough to protect your feet from shock absorption after impact.

The main advantages of this kind of plastic are its softness (not too hard) and its flexibility (not too rigid). It’s often used in furniture, footwear and packaging industries because it offers great comfort while being durable as well! You can find EVA foam inside car seats as well as sporting equipment like tennis shoes or golf clubs!

Each type of foam has its own benefits and drawbacks, depending on the application.

Foam can be used in a number of different ways, depending on your needs. If you’re looking for some cushioning or shock absorption, foam is a great option because it’s soft and squishy. For example, an office chair might have seat covers made out of foam so that they’re comfortable to sit on all day long. On the other hand, if you want to add some additional protection to something like a shipping box or container then it might be best to use some type of rigid material instead (such as cardboard).

In the end there are many different types of foams available depending on what kind of application you’re going after so make sure that before buying any type of foam product make sure that it will meet all your needs!


Foam is a versatile product that can be used in many applications. It can add comfort and support to your mattress, it’s lightweight and easy to transport, and it helps protect electronic devices from shock damage. The four main types of foam—polyurethane, polyethylene, polystyrene and EVA—all have their own benefits and drawbacks depending on the application at hand.
