Mee(ukkraine) Posted November 18, 2008 Report Share Posted November 18, 2008 Can you say to me what polyurethane is good for harshly grind? Where I can buy it in the web? Quote Link to comment Share on other sites More sharing options...
Krisboats Posted November 18, 2008 Report Share Posted November 18, 2008 It differs slightly from each manufacturing company. Your best bet would be to get in touch with some local suppliers and ask for some small samples. Quote Link to comment Share on other sites More sharing options...
Mikee Posted November 18, 2008 Report Share Posted November 18, 2008 (edited) It may bit a bit of a dumb question but what is the polyurethane for? Or what does it do? Edited November 18, 2008 by Mikee Quote Link to comment Share on other sites More sharing options...

psycholist Posted November 19, 2008 Report Share Posted November 19, 2008 (edited) There's a wide range of hardnesses available for the plastics listed there. If you have some brake pads you like, then getting them hardness tested and buying polyurathane in the same hardness would be a plan (If there's a university near you try the materials department). Here's a rough guide to the Shore hardness scale: http://en.wikipedia.org/wiki/Durometer - it's not absolute, but is a convenient way to compare plastics/rubbers. 90A sounds about right for brake pads.If you just want something that works for cheap I find these to be very good (Though they get eaten quite quickly on very harsh grinds): http://superstar.tibolts.co.uk/product_inf...;products_id=88or http://superstar.tibolts.co.uk/product_inf...;products_id=39The reds have slightly more bite I think, but there's very little to pick between them, so I'm using greens for colour coordination reasons ...

Alex Dark Posted November 19, 2008 Report Share Posted November 19, 2008 the durometer depnds on which supplier you visit....for example...one companies 90a might be abothers 87a....so its best to get a rough idea then ask for some samples Quote Link to comment Share on other sites More sharing options...
