Anybody Ever Make Their Own Plastisol?

Recommended Posts

This is an idea I've been kicking around in the back of my head. But...I wouldn't even now where to start. As far as I know nobody sells a liquid plastic that is similar to Strike King's Elaztec? I'd like to try to come with something similar. Any Ideas for making my own plastisol?

I've played with this bio degradable recipe http://green-plastics.net/posts/84/qaa-can-i-make-bioplastic-fishing-lures/

It comes out ok and would be deadly for creating scented baits , but the shelf life is horrible and its not very cost effective , good for a few days on the water and thats about it .

you can remelt it but its very liquidy , and it takes some time to solidify , so it pours well but would be a mess to inject unless a guy can modify the recipe some to thicken it .

overall its just a fun experiment but may strike some ideas

I spent a bunch of time researching this when I poured, and found next to no information on it.  I came to the conclusion that either: 1)  what earthworm said, and/or 2) the very few who actually DO make it are not willing to share any secrets........and understandably so.

I think the real issue is back to the Elaztec.  It is not Plastisol.  River2Sea is using a similar material on the back legs of their Dahlberg Diving Frog.

 

I talked to a couple of people "in the know" and that material is so new, so secret, that it is not available to the home hobbyist at all right now.  LOL, it is not even available to most big producers right now.

 

I know that I don't have any real pull, but I could not get these guys to even tell me what class of material it was. :censored:

Anyone still working on making bioplastic lures?  I came across the link from green plastics.net and tried it myself. I decided to try it because I found the start up costs of plastisol too steep and biodegradable is a plus. I have some POP molds of grubs, a worm and swimsuits.  I tried the recipe on the website and found it the right flexibilty but not enough durablity (tensile strength) when running a jig head through it.  Any one have the same results or better?  If better would you mind sharing the trick?

I tried a few things but durability is the thing that lets you down. Also, you cannot demold in a few seconds, cooling will involve the freezer or better still a bucket of iced water.

The recipes that I haven't tried yet involve gelatin. I live in an Islamic country and because of the way gelatin is manufactured it is considered 'haram' and so no shops stock it for the tiny western community.

I do believe a gelatin solution will be the closest you can get to a functioning soft-bait. I don't have a link but there is plenty of info to be found with a Google search.

If you get anywhere with this project, be sure to report back as I have no way of obtaining plastisol at a reasonable price.

Worked for a Chem co. that has made it or its like substances."PVC "After 39 years it retired me.!!Be careful.Be Safe.Read the safe practices on these chemical's.We have/had safe work practice's to work with these chemical's!! Wear your safety equipment when using these chem .Cannot be safe enough!!

@Vodkaman  I haven't tried cooling them down. I will have to try it.  Have you heard of agar agar? It is seaweed based gelatin. I have some and have yet to try it.

Agar agar is used extensively here as a replacement for gelatin. Yes, I have experimented with it a lot. The main problem is that it tears easily. I still have more experiments to try but I haven't worked on it for a long time.

Unlike gelatin which doesn't like to be boiled, agar agar needs to be boiled for a few minutes. This fact can be used for other additions. I am thinking mainly of the addition of half a teaspoon or even less of tapioca flour. This is just an idea and I haven't tried it yet.

What happens, when tapioca flour is brought to the boil, long strings of molecules are formed like in plastics. Unfortunately, considering tapioca as a soft-bait material is out of the question, as this molecule thing happens instantaneously and you end up with a big blob of gooey mess and a pan that needs some serious cleaning out.

My idea is to introduce enough string molecules to add flex and reduce tearing, but still keeping the liquid pour-able.

I will get some tapioca flour tomorrow and give it a go, as this idea has been on my mind for some time. I have plenty of agar agar in the kitchen as I use it for making ice-cream. The tapioca idea might have some spin-offs there to. I will get back to you with the results.

I have also read about corn starch, unfortunately I have not been able to find any here in Indonesia. Yes, it is all to do with starch. Tapioca may be too strong but there are other materials to try.

I am thinking; mix the tapioca flour in cool water in a blender. At this stage it is an easy to manage liquid with no mess. Bring the agar agar to the boil (use less water than the instructions as we are not making jello), then add the tapioca liquid with an atomizer or spray bottle and keep stirring. Each tiny droplet will instantly form the strings, but will be separate from each other.

This is all theoretical. I am hoping the molecule strings remain separated, but they may still clump together. There is only one way to find out. I don't have a spray bottle and so will have to add a drop at a time.
