API’s engineers use advanced designing and foam cutting technology to create the ultimate cushioning system solutions for your precision, impact sensitive equipment. But what are those custom foam inserts made of? Keep reading to find out!

Charcoal Foam

Charcoal foam is great foam for custom foam inserts which might come in contact with frequently used equipment. They are long-lasting and resistant to dirt, so they will maintain a professional appearance over time. Charcoal foam is an open-cell foam, giving it great air flow properties.

Anti-Static Foam

Anti-Static foam is a specially-designed foam used in the cushioning and transportation of electronic parts and equipment. The foam is unique, in that it allows for the slow dissipation of electro-static charges than can be given off by the electronic components inside the case, or even the human operators during the transport process. Anti-Static foam is perfect for custom foam inserts designed for cushioning sensitive circuit boards, computer chips and other electronics.

Polystyrene (EPS)

Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam that can be used for many applications, including packing material (think packing peanuts!) for cushioning fragile items inside boxes. It is light-weight, rigid, and easily formed to fit your custom foam insert needs.


Polyethylene foam is a strong and resilient closed-cell foam, ideally suited to absorbing shock and vibration. This makes it the perfect custom foam insert material for items that may be treated roughly during shipping. It is also found in flotation equipment and other marine products due to its incredible buoyancy.

Eggcrate Foam

Eggcrate foam, also known as convoluted foam, is visual reminiscent of its namesake. The eggcrate pattern can be cut from almost any type of flexible foam, and it retains the characteristics of the foam it was cut from. Eggcrate foam also provides more surface area for objects to rest on, which improves the air filtration of your custom foam insert.
