Webbing formula

The styrofoam formula? The only thing I can recammend is to use a rotating spinnerette as to make the webs like a thread, as this will greatly increase it's tensile strength.

[White_widow]

I found some extra time today! Okay, here's the deal on polymer science. The styrofoam formula is weak. The only way to increase a polymer's strength is crosslinking atoms. The tensile strength is increased by dry spinning in the case of nylon. I don't know why that works. Also, I found something interesting. I found out how spider silk goes from liquid to solid instantly. http://www.rsc.org/chemistryworld/News/2010/May/12051004.asp

to put that into words, there are salts that crosslink the formula, letting it to flow like a liquid. When acidity or pressure breaks the salts, it remains the shape that it was pulled into. I don't know how to do this yet. This is beyond the basic chemistry at my school.

[Symbiote-Man]

Nice! I was looking for a strengthener because if I can find one, I might make something really, really cool. A liquid to strengthen the substance to hold my weight would be ideal, but I have found nothing like that.

[Symbiote-Man]

I almost forgot, the "substance" I was talking about is a "homemade" gum composed of: gum base, contact cement, and the strengthener. I'll use about 45% gum base, 35% strengthener, and 20% contact cement.

[Spyder]

So you dudes want to swing from gum? Are we talking bubbalicious or gummy bears? What kind of gum is symbiotr man talking bout? Is that the only one or is there like another one? What kind if formulas has this forum come up with?

[Spyder]

Also, contact cement is kinda weak.It needs time to set right?

[Symbiote-Man]

The first page has all the info on that. I hope you are joking when you mentioned the two brands.
Are you sure, contact cement is weak? If it is, super glue will substitute.

[Spyder]

sweetness. well what kind of gum is it? Contact cement is not super weak but it is like weak when it doesn't dry for what? fifteen minutes? Super glue likes to destroy things though. Like have you ever put it on a T-shirt? It catches on fire and stuff.

[JMA610]

Welcome Spyder! Ok, heres the deal with the adhesives. Contact cement is used for it's instant bonding with other objects. Based on the formula, it should solidify with the fluid itself, as the oxigen crosslink in it can bond it to the fluid. The cement also contains acetone, which is the solvent of the fluid, or what keeps it a liquid. As soon as it is shot out, the acetone leaves the fluid, causing it to harden in mere seconds. The cement will do this too. But White_widow stated on the old thread that because of all the crosslinks, super glue could be added and would make the sides hard and tacky, not skin-bonding. I am still doing research on this part of it, but my shooter is almost ready for construction. If you have any questions, feel free to PM me for any further assistance.

[Spyder]

wow so many welcoming people! thanks guys. when for krazyglue stuff if you add orange juice and vinegar and salt like what it said in the forum ww talked about it will speed and make stronger the glue. (wow me inglish real good today... im in a hurry so i can't type well.) acetone wont dry very fast. what is a crosslink? i see the word but i dont really know what that means.

[Symbiote-Man]

Now I still am looking for a strengthener. I almost forgot, welcome, Spyder!

[Spyder]

thanks bud. Um what kind of gum is ti though? I can look for agents and stuff to crosslink gum but im pretty sure that changes based on the material.

[Symbiote-Man]

If you were to compare it to something, it would be closest to chewing gum. Good luck! I'll be looking too!

[Symbiote-Man]

Ok, I'll be a little busy for the next few months, but I'll still get on and work on the fourmula, just a little less.

[Spyder]

mmmmk. Is there a name for this stuff? I hipe that i can hear from you even though you're like going away.

[White_widow]

awww, leaving so soon? I just felt like I was getting to know you. I know how busy life can be though. I shouldn't really be on right now, however like a bad habit, it seems like I just can't kick this website. Hello, Spyder, welcome to the website! I hope you'll learn alot from this forum. I've learned loads.

Also, speaking of learning, I learned something about polymer crosslinks. I found out that depending on the amount of crosslinks it changes the properties. This is obvious, however I didn't take into consideration that Many crosslinks will make the formula too strong to be dissolved. I found out that the current formula might fall under that category seeing as though every single mollecule is touching something else. It might be a good idea to experiment with how much of the linking agents as too much might make it brittle.

To symbiote man- when you say gum, are you referring to either polyisobutylene or vinyl acetate? I can do some research on that for you. If you are looking at an elastomer, the best crossing agents are things that contain sulfer and heat, so that would be perfect for you since you are working on the glue gun shooter.

[Symbiote-Man]

I still will be on probably on weekends!
White Widow, I am referring to polyisobutylene. I realized, however; I can't hold on contact cement! I need to de-stick the gloves, or de-stick the part of the web I hold on to.
Also very helpful:
Apparently, the primary contents of spider silk turn out to be two amino acids, glycine and alanine, and researchers have recently discovered that the alignment of these amino acids is the cause for the web's incredible strength. Add that to the formula, and it should turn out great.
I was looking at the movie pic for The Amazing Spider-Man movie in 2012, and the first thing I thought was expanding foam shooting out a container when something is added.

[spidey44]

If you had a hot melt adhesive and a chopped fiber such as fiber glass would that make some sort of sticky rope?

[Symbiote-Man]

It certainly has possibilities, but depending on the shooter, it might clog it, instead of coming out with it.

[Symbiote-Man]

I just did some experimenting for expanding foam and it accured to me, vinegar and baking soda is a simple expantion. I did some experimenting with what I want in mind, and the best foamy acid and base combo is vinegar with lime juice, and baking soda with soap. That was very informative!

[White_widow]

Nice symbiote man. Good job doing the experiment. The contact cement should be good as because if you don't use that, the fiber will be hard to hold onto being so thin. Alanine and glycine are hard to get a hold of in their pure form though if you want to try you most certainly can.

The whole thing about the hot melt adhesive is certainly plausible once it cools, but all it would do is create a stronger glue stick. if you mixed the microfibers well.

[Symbiote-Man]

Good point, White Widow, but then will I be able to let go? I don't want to hang on a building for hours while someone calls the fire department!

[spidey44]

I was thinking of baking soda and vinegar for a web similar to silly string.

[Symbiote-Man]

So you add the vinegar when you want to shoot it? I really suggest just trying the formula I had. It turns out nice results and you can get soap and lime juice at your local supermarket.

[spidey44]

No. To make it foam.
