Very thick HDPE blocks

I need very thick HDPE blocks (6", 8", 10" thickness). Please could someone advise who sells this kind of HDPE. The exact sizes are:

1) 1 Pc. 150 mm thickness x 480 mm x 600 mm or 5.9" Thickness x 18.89"x 23.62"

2) 1 Pc. 250 mm thickness x 340 mm x 700 mm or 9.84" Thickness x 13.38" x 27.56"

3) 1 Pc. 205 mm thickness x 210 mm x 700 mm or 8.07" Thickness x 8.27"x 27.56"

4) 1 Pc. 150 mm thickness x 700 mm x 990 mm or 5.9" Thickness"x 27.56"x 38.98"

5) 1 Pc. 20 mm thickness x 1005 mm x 2010 mm or 0.79" Thickness x 39.57"x 79.13"

6) 2 Pcs Axel 240 Diam. x 1220 mm or 9.45" Diam. x 48.03"

Thank you for the help,

Those are some massive blocks. The closest that I am aware of is HDPE lumber, some of which can be as large as 6"x6"x___', or maybe even

6"x8".

The challenges in manufacuturing such large blocks are many. Removing the heat from a material with low thermal conductivity is never fun. In addition, HDPE shrinks as it cools from the molten to the solid (with further shrinkage as the solid cools).

Depending on your mechanical needs, could you consider building up these blocks out of smaller pieces? (As if adhering HDPE is trivial. NOT!).

If you could use UHMWPE instead of HDPE you could try a company called Perplas based in Bacup (UK). I came across them whilst doing my PhD and if my memory serves me correctly, they produce large slabs of material that are then cut into smaller blocks for use in medical implants (primarily). I think the slab material might well meet you size requirements.

Their web address is:

Eddy: We finished a project recently with a company in California using thick profile extruded HDPE that required Flame Retardancy. This is a construction material and pigmented blue. So, we know this is available on the market.
