What material is used for Chopping Boards?
 

What material is used for these white kitchen Chopping Boards?
I'm guessing it's a though material that can be used for blocks? hehehe :D
What do u think guys OK to use for blocks?

i think the material is called HDPE (high densite poly euthelne (meh cant spell))

i my opinion its rather soft to use for a waterblock, so for a simple design it would be ok. But dont try to do something small and complex.

The chopping boards are v good imo for blocks, and are the opposite of brittle, so overtigthning wont happen and so they wont leak from cracking like acrylic.
The plastic I used was low density polyethylene.
The only annoyance about chopping boards is they normally have a textured surface which needs to be lapped off so that you can get a good seal. the board I got was £8 and is enough for about 30 blocks :D
