below the overhang

[34ck]

What is the material that covers the bottom of the overhang on a fifth wheel called?

34CK -- I beleive it is covered with a sheet of 1/16' plastic. At least that is what it feels like to me when I clean that area

[34ck]

thanks, but what is the sheet of plastic called? overhang is made up of sidewalls, front cap, king pin etc. is it the overhangs underbelly or something else?

When the factory repaired mine they called it TPO white. .090 X 91 X 96. Vendor Part: 0909196 wtpo-c. That's all I know. It's some kind of plastic.

thanks, do you know what TPO stands for?

I am not sure what TPO stands for but I tried to wax it with a fiberglass approved wax and it streaked it. I won't say it melted it but it did do "something" to it. I just wash it now.

From Wikipedia.......Thermoplastic PolyOlefin (TPO) is a trade name that refers to polymer/filler blends usually consisting of some fraction of PP (polypropylene), PE (polyethylene), BCPP (block copolymer polypropylene), rubber, and a reinforcing filler. Common fillers include, though are not restricted to talc, fiberglass, carbon fiber, wollastonite, and MOS (Metal Oxy Sulfate). Common rubbers include EPR (Ethylene propylene rubber), EPDM
(EP-diene rubber), EO (ethylene-octene), EB (ethylene-butadiene), SEBS
(Styrene-ethylene-butadiene-styrene). Currently there is a great variety
of commercially available rubbers and BCPP's. They are produced using regioselective and stereoselective catalysts known as metallocenes. The metallocene catalyst becomes embedded in the polymer and cannot be recovered.

Now there's a mouthful !!

No wonder they call it TPO. There's some salt in it too. That sheet was costly.

Referringto you list of terms, cap, kingpin etc. the TPO is simply called a membrane.

Coroplast is also being used. The corrugated laminated plastic.
