Glad it is of help Ray.
More back in the day PE stories:
PE is used on all snowboard and ski bases, best all-around friction and maintenance characteristic. The factories make large sintered “pucks” of the stuff in massive hydraulic presses which cool for days before getting skived off like veneer. The highest molecular weights cannot be extruded or melted, they break the chains down, so they have to be sintered. The plates used on docks for wear against boats are made in a similar ways.
The “fastest” material was called Electra, it was loaded with so much carbon that it became electrically conductive, reducing the static electricity of very cold snow that could cause a ski to stick and slow down. Except that it was expensive, and only one company, IMS in Switzerland made it. They made only a limited amount of it a year. Yet somehow the biggest snowboard companies claimed it on all of their production, because black plastic is hard to differentiate. IMS went so far as to make an electrical tester to demonstrate genuine product. They came to the conclusion that it was a overall win to have everyone claiming to use their material as opposed to outing everyone as ahem liars, and did not push the point.
Sometimes the hustle is one step up the chain!
