Description

[Volek] A registered trademark for a cross-linked Polyethylene foam manufactured by Sekisui Voltek, LLC. Like polyethylene foams, cross-linked polyethylene foams are durable and chemically stable, but are typically finer celled. ^[1] Minicel is a closed cell foam. It is an extremely fine-celled bun foam that has a smooth, consistent surface. Minicel has a tough and firm, yet elastic feel. ^[2] Minicel has good thermal insulation, strength and shock absorption. It is impervious to mildew, mold, rot, and bacteria, as well as chemical resistance. Standard colors are natural-white and black. Minicel is very buoyant and is commonly used in water recreation devices such as kayaks. ^[3]

 == Working Properties ==
-PolyPlank is easily cut with a variety of tools, can be adhered to itself and other polyethylene-based materials with heat welding or hot glue. The 2” material has a useful balance of dimensionality, stiffness, and ease of cutting. Strips/blocks cut from it can be quickly laminated into much thicker cushions as needed.
-Common Fabrication Tools according to [http://www.paccin.org/content.php?267-PolyPlank PACCIN]:
-* Knife (deli knife, extendable box cutter, specialty foam knife)
-* Foam rubber cutter (electric) - For best results, mount cutter under saw table with an adjustable fence
-* Hot knife
-* Band Saw - For best results, use a scalloped or straight blade
-* Table saw - For best results, clean table saw blade frequently
-* Heat Gun
-* Glue Gun - Suitable with hot-melt or low-melt glue sticks
