Polycarbonate? (Cathar?)

pippin88 · 04-12-2004, 02:31 AM

I've heard mention of various grades/types of Polycarbonate.

I'm looking to grab a chunk for a GPU block I'm planning, and I want the most suitable type.

Cathar, you mentioned 3 types testing for the Cascade, can you tell me any more info on the one finally decided upon?

Also any idea of cost? I only need a bit about 50x50x30 or so, so I'll try offcuts etc.

have you considered HDPE or delrin? those are ones to consider without worrying about cracking.

In the end I just used a straight poly-carbonate.

You can get glass impregnated polycarbs (Lexan) which are a little clearer but somewhat more brittle, and you can get bullet-proof rated polycarbs (although I'm not sure of the exact difference between normal and "bullet-proof").

30mm thick polycarb may be an issue though.

Ok. May have to look at Delrin, but it's a little soft, and doesn't look as nice.

polyethelene is good. Soft = better imo, much easyer to make, only problem is there not clear.

do you guys source your materials online or through local shops? ive found no suppliers in my area so far.

mcmaster.com usplastic.com and onlinemetals.com are my main sources.
Delrin is actually pretty hard, it is softer than polycarbonate, but its still pretty hard.

i got this big of poly, 40cm x 60 cm x 1/2" clear
its like a board of metal that is light and clear.. so insane, so im looking for some thick black poly rod to make nunchakus ( i made about 12 original hexagonal wood ones with string chain thing ) and poly is perfect imo
the conclusion, dont worry what type of poly it is, as long as u got nylon barbs its good (brass wouldnt hurt it at all if u thread it properly)
