What Types Of Foam Can You Cut?

Foam is used in many different ways throughout our homes.

It can be used as insulation, for example, or even as packaging for food products.

Whatever the case may be, you can use these foam cutters to help you achieve the results that you want.

The following list contains some of the most common types of foam that you might encounter while working on projects.

Insulation Foam

You'll find this type of foam in almost every home.

It's often found wrapped around pipes and electrical wiring, helping them stay cool during the summer months.

You can also use it to insulate walls and ceilings. It helps keep heat inside your house, keeping it warmer than without it.


Melamine foam is commonly used as an alternative to wood. It's extremely durable, but it's also lightweight, making it easy to transport.

It's great for creating furniture, such as tables and chairs. If you need something to sit down on, melamine foam is a good choice.

Future Foam

This type of foam is often used for packaging purposes as well as crafting.

It's usually made out of polystyrene, making it both light and resilient.

This stuff is used to make puppets and small toys.

It's also recyclable, so you don't have to worry about throwing it away after you've finished using it.

Plastic Foam

These types of foams are typically used for craft projects, like building models and sculptures.

It's incredibly versatile, which makes it ideal for just about anything.

It's also quite sturdy, which means that it can withstand a lot of abuse.

Open Cell Foam

This type is similar to plastic foam, but it's not as dense. Instead, it's more open-ended, giving it a sponge-like quality.

This kind of foam is great for crafts because it absorbs water really quickly. It's also very soft, making it ideal for cushioning items.

Closed Cell Foam

This is the opposite of open-cell foam, meaning that it's denser and less absorbent.

It's perfect for applications where you need a hard surface, like when you're making boxes or crates.

Buyer's Guide

When you are looking for a decent foam cutter, there will be a few features that you will definitely be looking for.

You should make sure that you have plenty of features, good handling and precision cutting.

Here are a few things you should be looking for:

How Durable Is It?

One of the first things that you will notice about any foam cutter is how durable they are.

The best ones will last you a long time, even through years of heavy usage.

Items such as the Hercules 12-inch Foam Rubber Cutter Kit, the Hercules Hot Wire Foam Cutter Table and the Dominox Foam Cutter Electric Styrofoam Hot Knife Kit are industrial-strength tools that are built to last for years.

What Cutting Abilities Does It Have?

Another thing that you will want to look at is what abilities the tool has.

There are two main categories here: precision and speed.

Precision refers to how accurate the foam cutter is when it comes to cutting.

A good foam cutter will be able to cut straight lines with ease, and it won't leave behind any burrs.

The Dominox Foam Cutter can reach high speeds, using intense heat to sear through the foam, which is great if you are working with thicker material.

Does It Handle Well?

The next thing that you will want in a foam cutter is whether or not it handles well.

Some tools are designed to handle heavier materials, while others are meant for lighter jobs.

A good foam cutter will be comfortable enough to hold onto without getting tired.

It shouldn't feel too heavy either, since some people find it difficult to use them for extended periods of time.

Again, the Slim Pen Cutter and the X-Acto knife set are manual cutters that handle better than other models.

The second one comes with a range of sizes that will help you achieve different shapes.
