Chemically cross-linked foam is an extremely fine-celled foam, ideal for projects and applications that require thicker foam. With a smooth, pleasant feel combined with superior physical and chemical properties, our cross-linked polyethylene 2LB foam is the solution for an array of applications that demand thicker sections of closed-cell material. With its closed-cell density, this strong and reliable foam works well commercially as thermal insulation, construction expansion joints, and industrial gaskets. It is also used as packaging and in flotation equipment, with its low moisture permeability and high buoyancy.

Colors Available!
White and charcoal are available in all sheet sizes since these are common choices. The colors blue, light green, light purple, light red, and yellow are available in full sheets only.

Custom Cutting is Available!
While we offer commonly needed sizes at the ready, we can also cut custom sizes of cross-linked polyethylene foam for any project. Please Contact Us for details.

  • Health Care: Medical packaging, orthopedic and prosthetic padding, wheelchair pads, suture counters

I was able to determine which product suited my needs by looking at the website. The foam is being used to elevate small animal dental patients to make it easier to perform their radiographs.

Excellent product and service. Intended for lining boat hull where old spray foam was removed.

The phone arrived in an intact package. Yet there was a large divot in the foam which seems to be a manufacturing defect as well as some abrasions. Fortunately I needed only a piece of the larger foam.
First purchase went way beyond expectations

I am very pleased with my first of what I am certain will be many purchases. Excellent prices. Easy to order. Excellent product. Packaging was incredible - Fitting into box as perfectly as it was done couldn't be easy. Looking forward to my next purchase.

I used a total of 60"x84" to put underneath my very tall mattress to get it higher off the wooden frame to make it easier to change sheets. This foam is absolutely perfect. Really easy to trim, doesn't squish or smell. Thank you!
Great Foam, incredible Price, Fast shipping

I was preparing to get foam from an eBay dealer who was selling 5 sheets for over $300! I asked for recommendations and got recommended to foambymail. I saved a ton of money and they shipped it really quickly.
Works perfectly

I'm part of a medieval combat society/LARP. We use this foam to pad our weapons and ensure we're not breaking each other. Works perfectly! Good hit, good foam strength, and relatively cheap!
