HDPE/Acrylic/Nylon/RG1000

[Roboteernat]

HDPE is cheaper than RG1000 (reground UHMWPE) about 3rd - 5th cheaper. good impact properties - used to make rubbish chutes on building sites - those yellow tube things.
The main property benefit is that its a better bearing surface, low friction coefficient, which in our game is not a necessity.
We don't have water issues... yet... so this is a null point.
They both have great impact properties, albe it HDPE iis softer therefore will take the force better than shocking, but could lead to dents.

The only real difference is do you mind eventual dents - HDPE
You want to pay less - HDPE
less dents - RG1000
Green material - RG1000
White or black - HDPE or RG1000

trying to confirm the stat about the chute material, I see both HDPE and UHMWPE are both used to make the chutes.
