Title: UHMW
Post by: Dmaxshawn on August 17, 2009, 03:41:00 PM
Ultra High Molecular Weight polyethylene.  Just wondering if this stuff can be used to in risers or as tip overlays?  Heres a link to some info.  Would like to know if any have tried this before I go down the wrong path.  Thanks

I am pretty sure that no glue will stick to it. It is just a heavy piece of slippery plastic. I could be wrong but if it's what I am thinking of, it will not work.

Two Tracks is correct: you can't glue to UHMW polyethylene.  It's like teflon in that respect.  Also like teflon, polyethylene plastic creeps (i.e. constantly deforms under load) badly, so if you made a riser out of it and kept the bow strung the riser would deform over a number of hours - especially on a hot day.  Oh yes, and it's not very strong or stiff compared to wood.

Good I'm glad I didnt buy it.  The guy told me it was like phenolic.  I said ok and went on my way.

I work with that mat'l a few times a year....it makes a good cutting board though! I got a 2'x5' piece for just that purpose!
  The other guys are telling it right....not even close to phenolic. You should find a new salesman!

The only way you can glue it is to etch it with some expensive special etching solution, then there is a specific glue. rkmnt2 is right. Not even close to phenolic. It's tough for what it gets used for, but it's not hard enough for overlays anyway.

They use it on the bottom of drift boats to keep the rocks from damaging the bottom of the boat.
