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

The most common in art handling is PolyPlank LAM 220, with a relatively medium density of 2.2 lbs/ft^3 in a 2” natural tint(white) sheets at 108x48” or 108x24” planks.
'''Other Sizes and Densities'''
Laminated units are available in the following densities:
* PolyPlank LAM090 = 0.9 pcf
* PolyPlank LAM120 = 1.2 pcf
* PolyPlank LAM170 = 1.7 pcf
* PolyPlank LAM220 = 2.2 pcf
They are typically manufactured in 1/2" - 3" thicknesses, and 108 x 48" sheets, but other dimensions can be custom ordered.
PolyPlank EXT is the same formula as PolyPlank LAM, but extruded in one piece rather than laminated, and at a slightly higher price. It is available in the following densities:
* PolyPlank EXT170 = 1.7 pcf
* PolyPlank EXT220 = 2.2 pcf
* PolyPlank EXT400 = 4.0 pcf


* PolyPlank EXT600 = 6.0 pcf
''Produced in molded bun form.''


* PolyPlank EXT900 = 9.0 pcf
'''Density range:''' 2, 3, 3.8, 6, 8, 12 and 22 pcf.


They are typically manufactured in 2 x 108 x 24" planks, but other dimensions may be available for custom order.
'''Bun sizes:'''


'''Other Variations'''
* 2, 3, 3.8 pcf: 4 x 48 x 72”


PolyPlank LEL is formulated with less than 10% LEL (low explosive limit) VOC, which meets military and other low residual blowing agent specifications.
* 6 pcf: 3 x 48 x 72”


PolyPlank Renew is made with 40%-60% pre-consumer recycled material.
* 8 pcf: 1.78 x 32 x 67”


PolyPlank SFT is formulated with finer cells for a softer surface texture.

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]

Synonyms and Related Terms
