That's interesting that HDPE and HDPP can be solvent welded. It will be especially nice for your customers if they can screw your products together and inject #3 or #4 along the seams. I may have to cut up my cutting board and go experiment with that. LOL. *****
Chris #3 IPSweld are for acrylics only not the hdpe&pp materials
Regarding the weight of the HDPP, that's impressive that a 5'x8' sheet only weighs 66 lbs. That works out to 53 lbs per standard 4'x8' sheet which is online with 1/2" standard-core plywood.
Yep thats why i use it its not as light as 1/4" plastics but the extra weight in my opinion does have its place in cages where larger snakes come into play as it can help iliminate the cage being moved by a tail grab etc , and to me the weight is only a issue when initial set up ofthe cages etc are done as normally the things are moved around like furniture lol
Some questions regarding HDPP:
1) Is the quality generally pretty good or are there a lot of products that are warped, etc.?
if you are reffering to the material warping in use ? as with any plastics depending on the load spread on it when stacked tec they can warp if the weight isnt distributed equally . As far a sheet materials being warped or prone to it the answer is it will warp up in direct sunlight when laid out or if leaned on a wall etc but it doesnt per say form amemory to it where it cant be reversed easily.
2) How does the price compare to Expanded PVC from a given supplier? I realize comparing 5x8 to 4x8 sheets is not straightforward.
Well my suppliers XPVC(sintra) in 1/2" is a 4x8 and is about $25 or so less then the hdpp, i was going to use the XPVC but with the center core being " foamed" it has a softer inside core therefore a mechanical screwing can be done but can also strips easier and has ALOT more flex to it i built a arboreal cage with it as a trial cage when using it as a test and it was unbeleivably flimsy so i chooseto stay with the HDPP
3) How is the rigity or how well does it span across longer lengths?
On a 8ftx30x18 cage on the length of 96" there is a small deflection in the length of the cage maybe 1/2" but with a solid machined face it allows the structure of the front to stay rigid and not have any sagging to hamper door movement /operations. On the width of 30" deep there is some deflection but again it doesnt have ill effects to the cage and with a installed rail support frontto back it will provide ample support to the cage itself ian all i think its one of the most rigid plastics to use for rigidity over pvc and similar products due to the compound in the plastic.
4) Is it offered in colors other than white? You use a black or a dark blue, correct?
I use black , grey & white. there are some other colors such as a "seafoam" and similar shades but when you get into the more custom colors likethat the price range increases greatly.
5) Do you know of any national suppliers of 1/8" perforated polypropylene? I have found US Plastics but their products tend to run on the high side.
i think my supplier carries it i think i had asked several months ago as iwas planning to make like a FB style rack and was going to use that as venting for the top of the racks over a full screen opening as it would keep humidity in alot better and heat also thats still in the works as it will be made with aluminum modular racks etc so they can be a multi use rack and not limited to one size tubs for it .
Oh yeah, I did mention Sintra in my post under PVCX.
take care
