Acetal Topped DD Maze4 GPU
So wandered through DangerDen's site this morning while I had nothing to do and noticed they were making blocks with a top out of a material I had never heard of before.
Upon further investigation I found this helpful description on MatWeb. http://www.matweb.com/reference/acetal-polymer.asp What worries me the most is that DD did not pick a substance resistant to corrosion, yet again. The document clearly states that the material breaks down under basic OR acidic conditions, and I'm pretty sure that water is naturally slightly basic... Sure, it's durable, it won't break because you drop it, it won't crack or shatter (something i'm thankful dangerden DID address if some of you remember my posts about the two cylindrical reservoirs they have sent me.) But I'm not too sure I'd want little flakes of this coming off and getting into my lines. =\ Personally I like shiny things anyway... Go brass and chrome! -Zoson

About time a mfg makes a delrin topped block, acetal and delrin is virtually the same thing.
It is quite smart that they finally made one, I bet they rip through those tops 10x faster than they did with the aluminum ones. but I had the first acetal topped gpu block! Jon |

zoson as j fettig stated acetal and delrin are the same thing, incase you havent noticed cathar's new g4 blocks are delrin topped.
aslong as they are black delrin there shouldnt be any problems with uv related degradation, also im pretty shure pure water (read distilled) has a ph of 7 (neutral) so shouldnt be a problem. plus i believe most water additives that ppl use in thier loops are alakaline in nature. i think i mucht grab one of those in the future to replace the clear top on my rbxif they start making those in delrin. also i no longer have a reason to not get a maze4 GPU instead of a cyclone fusion HL

Does anyone know the respective pH's of water wetter and other additives? Someone needs to make some all copper blocks including barbs for paranoids like me. =P I've seen too much galvanic corrosion and leeching in my watercooling lifetime to trust any of this mix and matching of alloys, metals, and polymers. -Zoson Edit - one more thing, just because cathar uses something doesn't mean that it's 'the best' he has to make production sacrifices also. As you stated, and as I imagined, acetal and derelin are easier to mill = less time on the mill = less cost. I do respect his decision to use derelin, but we haven't seen it used before, nor have we seen any long term installations. Hell it took the enthusiast community years to stop mixing al and cu. in fact we're still doing it.

Do you even have numbers to how much delrin breaks down at what pH? How is it affected exactly, cause I'm pretty sure it doesnt just dissolve away.
Do you trust plastic parts in your pump? I'm sure many pumps are made of this or similar materials but handle everything fine. Tubing? I'm sure at some pH, tubing will begin to degrade. So you dont even want solder in your radiator coming in contact with the water? Irrational fears.

pH - can we award dunce caps to some of these guys ? assuming that they do not wish to be known as such (???) try the frontal lobes with that wire |

When materials sheets say "sensitive to acid or base" they often mean the material is not suited for the EXTREMES. Since water in our systems is not going to be pH 1 or pH 13 then it's not really an issue I don't believe.

buy a college intro text describing plastics, learn about the types
google extensively on the corrosion resistance of plastics understand the types of (ASTM) corrosion testing (for plastics) and the intended use of the data it is something of a black art for some plastics in severe service, not for our app though -> THEN you can say "Well there you have it folks, derelin is not a safe compound for your system." that you have declared yourself an incompetent fool is your concern when you start posting stupid shit, like your 13 yr old ?, then I will call you a fool who cares if foolish incorrect info is posted "respectfully" ?; better by far to have not put up the bogus finding zoson has reproached me for namecalling by using the word "fool" not so, people are characterized by their actions consider it a considered description Last edited by BillA; 01-13-2005 at 12:34 PM. |

I wish I had the delrin top for my maze 4, it is one heavy beast.

Sorry zoson, I'm going to have to side with Bill on this one (many heads shaking yet?!?).
It's easy to get mislead with technical information, like MatWeb. If you had compared the substance with others that you are familiar with, it might have given you an idea of the extent of the corrosion resistance. Specifically, try comparing iron with acetal, and see how different they are. then check a few other substances in between (copper, alu, nylon, silicone) for a clearer picture. I'm going through the same exercise to identify a good insulation material (also through MatWeb) for my heat die. |

Ben
let me know if you find anything better than phenolic for the die itself I'm needing some for more dies |

it is the interweb. the interweb knows everything. if you ask google. it will tell you everything you want to know.
there is not excuse for ignorance. if you dont know something, dont post something as if you do. |

What with millions of cars on the road, we could be looking at incredible problems. This is just a total DISASTER!! How could have all the senior engineers at so many companies have gotten it so wrong all this time? The horror! The humanity! /me weeps and sobs inconsolably at the very thought of the scale of the world-wide disaster that is about to happen any moment now! |

ah Scott, I live with that thought every day
- because I violate that maxim daily but it seems so right at the time . . . . . its corollary BTW is "Children should be seen and not heard." obviously an English upbringing |
