HDPE

Who makes the HDPE for the FRC scoring platforms?

Re: HDPE

HDPE is a fairly universal plastic, so it's unlikely that they have a specific manufacturer.

Re: HDPE

I don't think the manufacture matters. HDPE is basically the same no matter who makes it.

High Density PolyEthylene. As stated, very common plastic.

Re: HDPE

HDPE is the stuff that plastic milk gallons are made of. Imagine a bunch of those melted down and formed into a sheet. It's lightweight and relatively strong. Team 20 used HDPE on our 2013 shooter to give the frisbee a slick surface to move on while in contact with the shooter wheel.

The HDPE surface of the scoring zones will probably be comparable to the lunacy surface.

But don't plan on melting a pile of milk bottles!:eek:

HDPE has been used often in previous years' games.

They make great fire starters for your fireplace or wood stove. Crumple them up and use a paper towel for a wick. HDPE burns virtually smokelessly and with no odor.

Re: HDPE

McMaster-Carr has sheets of HDPE in various thicknesses and areas. For example, a 4' x 8' sheet 3/32" thick is about $60 (8619K78). Shopping around a bit should find a better price.

So HDPE is a slicker plastic surface then? Will the crates slide easily on it? Too easily? We gotta get some of this stuff in to practice with.

Most 5 gallon buckets are HDPE and usually say it. Play around with them until you get some sheets.

Yes HDPE is a slippery surface. It has been used in some previous FRC games -- one notable use was the top of the ramp in 2003, where it made for quite a challenge to hold a KingOfTheHill endgame position.

I expect totes to slide more easily on HDPE than they will on the smooth side of Masonite board, which is what the low-cost scoring platform drawings call for.

Re: HDPE

HDPE is very slippery to standard FRC tread. However, colson wheels get absolutely amazing grip on it. Like legitimately amazing.

Re: HDPE

HDPE comes in more than one finish, and therefore friction coefficient, including smooth and starboard (not as smooth). The game drawing only says "Material: HDPE, .25" Thick, White". It would be nice to know which finish.
