Acrylic tubing

[mixtizo]

If i were to use clear acrylic tubing with white coolant what are the cons that could happen?

Will there be gunk build up, will the tubes change color even tho there clear?

[Freaky_spider]

acrylic wont change color, 

 

the gunk build up obviously depends on what coolerant you'll be using...

 

id recomend mayhems pastel white

[WunderWuffle]

Acrylic tubing is better than regular tubing because of a few things. They don't stain (at least the good ones don't), they don't gunk if you're using quality coolants. Because they don't leech plasticizer unlike regular tubing, they're generally more durable in the long run.

 

I don't really see any cons other than having to bend the tubing or use a whole bunch of angled fittings.

This.

 

Acrylic is a long term tube,it will not need replacing for the life of the rig.

Get PETG tubing, much better the straight acrylic tubing. Just bought 14 36 inch tubes of it myself the other day

If only it was......

 

Its not.

What would be the negative over acrylic tubing?

Its primary used for food and medical packaging,PET is used for fluid based materials.

PETG is gas and water permeable.
 

 

PET's primary market is packaging for soft drinks, bottled water, fruit-based beverages and iced teas. PETG is chiefly utilized in food, medical and electronic packaging

 

"We foresee improvement in impact strength, service life and resistance to hot water, as well as a broadening of the size range produced, leading to new applications," said Leger regarding the market for PET.

 

 

Remember that PET is better for fluids.......not PETG. Hot water temps not given however.

See that the application list is restricted to oil bases.

 

Coupled with the fact it can be cold bent.

 It holds fluid just fine as that part has already been proven and the UV lighting would have to be very intense in order to make the tubing a yellowish color . I know that its new to the community but honestly you are the first that i have seen say something negative about it. The reason I went with it over acrylic is that it takes less time to heat, and bend, hard to crack and no kinking in the bends. This is my first time using PETG but I'm use to bending acrylic tubing and piping alike, as I was a plumber for 3 years, but there seems to be more positives then negatives over acrylic. Maybe I'm missing something, do you think fluids will eat at the PETG tubing over time and cause it to leak and thats why you think it's not as good as acrylic?

PETG is simply too new for this market in my opinion. I would be selfish to say I want you to get it and let us know how it fares in the short and long term so the rest of us can make a more informed decision.

Not selfish at all, I'm not sure if you were asking me or the OP but just the other day, i bought 14 36inch tubes, so I'm kind of stuck with it and i will be using it in my wifes build, so I will be able to keep you up to date, short and long term if you guys would like?

[VSG]

It was addressed in general but since you are set about using it, I would definitely appreciate your experiences using it- both in terms of bending/installing and maintenance over time

What about strength and rigidity? I saw this video on Modzoo awhile back, I was somewhat intrigued:

I will defiantly do that for you guys.I will make a thread just on the PETG tubing when I start the loop on my wifes build for you guys

-Snip-

Li also did a video about PETG tubing as well, and only had positive things to say about it. granted he has only been testing it for a short while too, but he has yet to find a con about it either.

Whats is this obsession with acrylic being weak? Its far from weak...there is a video in the hardlines thread showing the massive amounts of deflection and return to shape. If you think a hammer test is an indicator of anything other than impact strength then you are mistaken.

 

 

 

As for the only negative thing...well,try the modzoo site where there is a nice post about the tubing deforming because it got warm from coolant.

 

 

 

By all means try it,im not being held responsible tho.

I personally don't care about a hammer test, I just like the fact that it was proven more durable then acrylic. I dont think anyone from the community is going to start beating up their loop inside their builds anytime soon with a hammer lol.

 

I think I know now why, you did not link the modzoo link-http://themodzoo.com/forum/index.php?/topic/1338-petg-problem/ . The tubing deforming was caused by the pump not being on, the PETG tubing it's self was not the cause .At that temp even acrylic could have deformed.

 

I do see your concern though and anything new will do that to people.

[B NEGATIVE]

Acrylic would not have deformed at that temp. Where did you get that idea from?

 

The link I posted even states that PET (the liquid carrying version) has poor resistance to hot water

 

And at no point has anyone proven PETG is more durable than acrylic,that is simply not true.

 

If it is as you say more durable then please explain why block manufacturers are not all over it...they are not because it isn't.

 

Please feel free to post here http://www.overclock.net/t/1388300/acrylic-pipebending-101/0_20 If you require an opinion other than mine,there are a couple of chemists that post in that thread that also do not rate it for our use.

 

Btw,I didn't link it as im on my phone,no other reason.

 

 

 

If you are making a loop with it then by all means be the guinea pig and post your results in the hardlines thread

[ericlee30]

Acrylic would not have deformed at that temp.

 

Where did you get that idea from?

 

 I actually think I was wrong on that part, not sure, here is a quote that i found. "The maximum temperature at which acrylic plastic can be subjected to for any period of time is 180°F/82.22°C to 200°F/93.33°C. The material softens when heated to temperatures above 260°F/126.66°C. Applications subjected to high heat sources should be avoided or temperatures checked to allow for an adequate safety factor. An alternative clear plastic to use would be Tuffak Polycarbonate with a service temperature of 270°F/132.22°C." - http://forums.pugetsystems.com/threads/5781-FYI-about-Acrylic-Temperature-Tolerance

 

PETG data sheet shows that in section 9 that the melting point is 437-500°F/225-260°C. for rod or tube form. on page 2 section 9 http://www.cityplastics.com.au/site_files/687/pdf_files/pet%20msds.pdf - Site: http://www.cityplastics.com.au/materials-petg/

 

Now remind you, I am in no way shape or form a expert on acrylic nor PETG nor am i claiming to be, just reading on the differences of both, as i too have never messed with PETG ( this will be my first time with it), just have messed with acrylic.

 

Melting point:

225-260°C / 437-500°F

Section 9 Physical a

nd Chemical Properties

225-260°C / 437-500°F

Solubility in water:

Insoluble

Volatile content %:

<1%

Specific gravity:

1.33-1.43

And at no point has anyone proven PETG is more durable than acrylic,that is simply not true.

 

 

 

 

Seams more durable to me.

 

Btw,I didn't link it as im on my phone,no other reason.

Awe, ok that makes since now bro my bad

[B NEGATIVE]

Let me rephrase that,no one has proven its any more durable for our use.

 

The alcohol issue is well known.

 

The cold bending is not something you desire for a tube that is being held in place with pressure.

 

Impact strength,again not relevant.

 

Now,read this...

Acrylic always scores higher except for impact resistance.

[rjbarker]

^^^^ Been reading a lot of good info re: PETG Tubing over at both Overclockers and it seems (from 90% of what I've read), its the new preferred over straight acrylic....intersting for sure..

 

Someone mentioned a positive of acylic was "it never has to be rplaced and lasts the lifetime of your PC)...got a kick out of it....I use maybe 4.5 ft of tubing in my build @ $2 / ft and replace with an annual service

The lifetime of one of my Rigs, withiout going thur some change that is going to require new Loop is about 2 yrs/....maybe....

Hmm very interesting, there is so much on this it makes your head want to explode LOL

 

Back to the guy on mod zoo, do you think the pump, played a big factor in the PETG doing that or do you honestly think over time, PETG will naturally do that regardless if the pump fails or not?

I know that the pump was the reason but it should never of happened,even crappy normal tube wouldnt do that yet alone acrylic. The water never even got close to the melt point but the tube still deformed? Then claiming the 'superior strength of PETG' saved his loop when really its the tubes weakness that caused it..

I have serious doubts on the long term application of PETG,only time will tell.......
