Most Popular Foam Comparison

TopGuard PE (Polyethylene)

Applications:  Good for heavier objects that need to be snugly secured in place and objects that can absorb a modest amount of shock

Surface: Smooth (similar to a pool noodle feel)

Colors Available: Black, Blue, Red, Yellow

Density: High

Cell Type: Closed

Moisture Resistance: High

TopGuard PE Foam​ is a dense closed-cell foam that is our recommended standard for most applications. It is moderately pliable and offers a secure, snug fit known for greater durability and stronger cavities. 

The top layer of a ​TopGuard PE Foam​ insert consists of a high density 1/4 inch color topper laminated to standard density Black Polyethylene foam. The top face of the foam and the top face inside of the cutouts will be in the TopGuard color of your choice. The sides of the foam and the sides of the cutouts will be black. 

ProCell (Premium Look)

Applications:  Good for heavier objects that need to be snugly secured in place with similar protection to TopGuard and a more premium look

Surface:  Smoothest (suede-like feel)

Colors Available: Black

Density:  High

Cell Type:  Fine Closed

Moisture Resistance:  High

ProCell Foam is a closed-cell, irradiated crosslink material with a high level of rigidity and stability. It is similar in density to TopGuard (PE), but has smaller cells that give it a consistent, suede-like finish and premium look. 

ProCell is available for an additional charge when purchasing foam to fit a specific case (make/model). The price is about 25% higher than TopGuard PE or Ester.

ProCell is not suitable for industrial use as the foam surface may pit or scar from rough handling; rather, it is more suitable where a professional look is required, such as for presentation or sales rep cases.

Charcoal Ester (Polyurethane)

Applications: Good for more delicate (e.g., crystal stemware) or irregularly-shaped objects (e.g., digital SLR camera) that may break on modest impact

Surface: Semi-smooth (sponge-like feel)

Colors Available: Charcoal

Density:  Low

Cell Type: Open

Moisture Resistance: Low

Charcoal Ester Foam is more spongy and pliable, exhibiting excellent shock absorption and malleability for delicate objects like glass.

It is a soft, low-density foam that requires more space between objects within, in general. As an open-cell foam, Charcoal Ester has less moisture resistance, absorbing water or other fluids.


Lid Foam Types

Convoluted (Egg Crate)

The standard for lid foam, offering suitable protection while securing case items in place. Highly recommended for designs where items protrude from the base foam into the case lid.

Alternative banner alt

Solid

Appropriate as lid foam in situations where case items all sit flush with the surface of the base.

Alternative banner alt

PrintGuard

Our print-enabled specialty foam for customizable one or full 4-color printing on the lid foam.

Alternative banner alt

Custom

Commonly used when items protrude into lid foam. Foam can be cut to perfectly form to the items in both base foam and lid foam.
