Vycom Seaboard High Density Polyethylene Sheet, Matte Finish, 1/2" Thick, 12" Length x 24" Width, Polar White

Ordered 12" x 24". The piece I received is 11 5/8" x 24"It say plus or minus 1/8" not 3/8". Big difference

Worked great for my project. Used it to make a wake shaper for a boat.

I was melting down my own recycled HDPE from Milk jugs to make molds to cut on my CNC Machine, but I sometimes ended up with air pockets that will ruin a mold. So I purchased a sheet of this. Excellent stuff and I don't have to worry about voids. I guess I will have to find something else to do with the milk jugs to keep them out of the landfills because this stuff is awesome!

Exactly what I was looking for to use on my boat dash for an instrument cluster. This is the real stuff, not the junk you see out there and the price is fantastic. Package arrived on time, well packed and worked perfectly for my needs.

Great for making parts for the boat. Works well with woodworking tools and holds up against the harsh saltwater enviornment

This arrived with a spot of dirt on the surface that doesn't wipe off. There was a protective film on the face, but something broke through the film and left a smudge. Otherwise, as far as I can tell it is as advertised.

This is great to build custom dividers and support pieces on a boat. It is easy to cut and drill for any application.The 1/2 is very rigid and strong marine board. I could have easily used 3/8 or even down to 1/4 width board.

made resin molds out of it. Resin did not stick to it
