Review on Premium Seaboard Density Polyethylene Finish Length: Durable & Versatile by Mark Morrow

Mis-sold. It is a hard, high-density polyethylene. Not 1/3 lighter, no foam core. This is ordinary high density polyethylene. I have two pieces that measure 11 7/8 inches (about 1/8 inch). It is 301.625 mm on both sides. Its thickness is 9.525 mm. Weighs 825 grams. If you calculate this you get a density of 0.95 g/cm3 which is the density of standard HDPE. As for HDPE, it's nice and flat, looks good and handles well. I would give it 4 stars because the lack of size due to the cut of the blade can bite someone who needs a full 12 inches. As for Light HDPE, what it says on the product, 0 stars because it's not the same at all.
