Post All About Derlin

-Nowadays, delrin is the shiznit, and if it is made from delrin it must be good. Why is delrin so popular though? Well, to answer that question, we need to understand why metal bolts are so unpopular, at least for impulses.

-When you buy an impulse for instance, one of the first upgrade you should by is a delrin bolt. Why delrin, what is wrong with the metal bolts? Well, the main thing is friction. Since no metal has a perfectly smooth surface, friction is created when the bolt moves (like rubbing to pieces of sand paper together, but on a smaller scale), so that means you have to use some sort of lubricant to let the bolt move smoothly. Also, since the metal doesnít have a perfectly smooth surface, it will not seal properly and will require o-rings to make a complete seal, which will, in turn, create more friction that further slows the bolt down and requires -the use of even more lube.

-So how is delrin better? Well delrin is a type of plastic that is ďself lubricating.Ē Now that statement is a little confusing, because the bolt doesnít lubricate it self or anything, what is does is that the type of plastic delrin is made from doesnít create any friction when it moves against a metal surface so that means you never need to lubricate it *. Also, since delrin has a perfectly smooth surface (actually, on a very small scale it acts like a sponge that can change itís circumference just a tiny tiny bit which enables it to expand/decrease in size to fit the bolt chamber perfectly-you wonít be able to notice this though, itís not like you can squeeze the bolt and it will squish like a sponge or anything like that), no o-rings are needed because the delrin creates a perfect seal (which means no lube, blowback, and friction). Also, since delrin is a type of plastic it is much much lighter than the stock aluminum bolt, and delrin bolts on average weight at least half as much as the stock aluminum bolt, if not one third as much as the stock bolt. That decrease in weight means that the hammer can cycle faster, partially because of the reduced weight and partially that the center of mass now lies over the hammer (which is heavier than the delrin bolt) so it has less resistance when it cycles. The decrease in wieght, on some impulses also mean that you can turn the operating pressure down which means less chopping and more shots per fill. Another plus for delrin is that since it is a softer material than metal, it wonít scratch up the interior of your impulse like the stock metal bolt will. If anything, the bolt will get scratched up, not the interior of the gun (which would you rather have to replace, a new delrin bolt for 30$ or a whole new body for your impulse for at least 300$?).

-Well, is there anything out there that is better than delrin? Yes. How could anything be better than delrin? Well, there are different variations on delrin, but most types of delrin have the ability to absorb water (for the same reason it can form a perfect seal, it kinda soaks the water up like a sponge). If you clean your delrin bolt with water for example, or live in Louisiana in the humid seasons and leave you bolt out of your gun for a while, there is a good chance that the bolt will absorb water, expand in size just a tiny bit and not fit in your gun anymore. No, that isnít a major problem, and in fact, there are no major problems with delrin, just little nit picky ones. Another little down side to delrin though is that is weaker than metal and thus wonít last as long-but like I said before, which would you rather have to replace, a new derlin bolt for 30$ or a whole new body for your impulse for at least 300$? Also, since delrin bolts weigh so much less than the stock aluminum bolts, they have the ability to throw off the internal balance of the impulse, which can result in erratic velocity and your gun acting up just in general (I do not know why this is, I mean, I would think the lighter the better, but this isnít necessarily true). For example, the stock internals of the impulse weigh 1526 grains and just by adding a delrin bolt, your internals will then weight, at most, 1177 grains. Now since, for another reason I cannot explain, all impulses act a little differently from one another, this will be a problem for some, but not for others. If it is a problem you can solve it by buying a brass hammer (which weighs considerable more than the stock aluminum hammer) for 20$.

-So tell me, what material is better than delrin? Well, their isnít one specific type of material that is better, but some companies, like FreeFlow and Bandit Bolts are starting to make bolts out of nylon composite materials (some called nylatron). They have all the benefits of delrin, they weight about the same, yet are stronger and do not absorb water like certain types of derlin. There is no down side to nylatron.

-In conclusion though, I would go with a delrin bolt for your impulses instead of a nylatron bolt though. Delrin bolts are easier to find, cheaper and now come in any color (from wermmods/imperial paintball at least).

-Nylatron>Derlin>Metal

-Hope you all could understand that, pm me if you have any questions.

* You actually shouldnít be lubing your delrin bolt on your impulse because the lube acts like glue and slows the bolt down-not to mention delrin is meant to have a dry surface and only functions best with one.

Nice work, Chief. Your an asset to PBReview. I wish I could sticky all your posts, but the problem is if we did it'd take up the whole page.

It will certainly get into the Ultimate Sticky.

I still kind of new to the pbreview.com forums, but is toothpastedog a mod yet? He should be a mod if you can make him one. If it's possible to nominate him to be a mod, I nominate him.

A quick correction. Its delrin not derlin.
A link to duponts description.
http://heritage.dupont.com/floater/f.../floater.shtml

Oh yea, since its made from formaldehyde, if its burned it releases formaldehyde gas. This isn't something that you would want to breathe in.

Toothpaste, you dont want to be a moderator. See, I use to be a lot like you back in the day. My sig was much like yours even... I got praises all the time... made many helpful threads

Than I became a moderator. Now I don't have as much time to post useful threads and information like you do. Now most of my time is spent sifting thru threads, checking all the reports I get, stickying threads, and get morons banned.

Enjoy yourself while you have no responsibilities.

Exactly, when i joined, it was my goal to become a mod, but now even before reading your post, i have come to the conclusion that i would hate being a mod (although a title like "Impulse Dictionay" wouldn't hurt, lol), i would hate not being able to help people and just spending my time stickying stuff. So thank yall, and thanks calebd2

a little trick for those worn nasty looking delrin bolts- drmeml with polishing wheel, but instead of polishing compound, try some dow 33. it will alow you to buff out most any imperfections, marks or tiny scratched sections and restore a slick finish. i have done it to my equalizer bolt and my intimidator bolt, and it has worked wonders in keeping both in top shape. if you have one of the variations in delrin that really likes to expand from grease, don't try it, but every bolt i have done it to has had no problems
