2025 Bumpers

I’m curious as to peoples thinking about the bumper rule changes for 2025.

The memo indicates that two new materials will be allowed/recommended for cushioning in bumpers:

  1. Solid Polyethylene (PE) closed cell foam with density between 1.5 and 3
    lb/cu ft.

  2. Solid Ethylene-Vinyl Acetate (EVA) closed cell foam with density between
    2 and 6 lb/cu ft.

Is there any good reason to believe that one of those two materials is superior to the other from a robot protection standpoint? Based on a little looking around, it appears that the PE closed cell foam is less expensive and maybe easier to obtain (Home Depot sells 1" thick sheets of 2 lb/cu ft material)

Looks like it’s time to rebuild bumpers.

There’s a lot of discussion about it here:

Please continue the discussion there.
