bass4cache Posted April 6, 2012 Report Share Posted April 6, 2012 This is what I exeprienced with one vendors plastic being heated in the microwave. Took about 10-12 minutes to get it to a usable state. It may work great for some people but this is my experience with it. I'm not hear to bash this plastisol but people talk about bubbles and I dont ever recall seeing actuall photos of the froth. I have experienced bubbles, foam and froth numerous times from numerous plastisol vendors so I am very familiar with them and how to work with them. I could go on and on but I just wanted to share these pictures of the various states of one cup of plastic without any additives. If you would like to know anymore you can PM me. https://plus.google....153812558868065 Quote Link to comment Share on other sites More sharing options...
jeff@mf Posted April 6, 2012 Report Share Posted April 6, 2012 Number one on the list it looks like moisture or water to me hope it is not from my supplier me. There are many ways to introduce moisture into your plastics. I guess first is your microwave and measuring cup clean? Jeff@MF Quote Link to comment Share on other sites More sharing options...
Travis Posted April 6, 2012 Report Share Posted April 6, 2012 (edited) It had tons of bubbles before even heated by the looks of the string of pics. Did it just get shipped? That is a lot of bubbles and it looks like you cooked it to boot trying to get them out. Just going by the second picture since the froth/bubbles already look light yellow/tan in the center portion. Calhouns shouldn't even get that tinted when heated. That would be one I just dumped if microwaving but chuck it into a presto pot maybe not as of an issue. I have wanted to run some of these plastics at work and see what the volatile composition and percentages are of these "bad" batches. This is about the worst I have had bubbles in many years. 4 oz plastic, shaken in jug with nuts/bolt set up, heated in microwave, stirred with metal spoon.

gone2long Posted April 6, 2012 Report Share Posted April 6, 2012 Wow yeah something is not right but I've read to recover that condition that guys will torch the bubbles of the top and proceed as normal, but that looks like another player at work for sure.

bass4cache Posted April 6, 2012 Author Report Share Posted April 6, 2012 Not from MF. No water and a clean cup. Just delivered and tried it out. So whatever the problem is it came like this from the vendor. Like I said I've been doing this long enough to know that it's not my method, rather the wrong product for Microwaving or just an inferior product. The pics are in order of cooking. 1st one is cooking after 2 minutes, the second one after a couple of stirs and a few more zap at 30 seconds and the last picture is letting it sit for about 5 minutes. That kinda cooking and waiting time just isn't going to work for my applications. The torch trick does work but not in this case, the froth was from top to bottom and the worst I had ever seen, I've accidentally cooked plastic with some water in it and it wasnt even this bad. You can cook moisture out slowly. But these bubbles just hung on forever. I would complain to the vendor but I would think that any company that ships this stuff out would have at least quality tested it at some point before releasing it. Maybe thats the wrong attitude, but I've learned over the years just to write stuff like this off and move on. Just another lesson on what products I like and which ones I dont.

carolinamike Posted April 6, 2012 Report Share Posted April 6, 2012 (edited) bass4cache, you told for how long you heated the plastisol but you didn't say whether or not your microwave has a heat setting. And from the times that you gave, it sounds like you were heating real fast, some plastisols will tolerate fast heating in the microwave better than others, but all plastisols do better when heated low and slow. Also I'm a little confused you also said you had bubbles from top to bottom, on the third picture that you show, you can easily see all the way through the plastisol, and it looks like a couple of dips with a tablespoon to take the bubbles off the top and you're good to go. And I also don't understand why you wouldn't contact the vendor if your're having a problem. Since you've already stated that it's not Jeff's plastic, and let's just say for example that it was, I'm sure Jeff as would all other vendors feel like they deserve a chance to make it good. Everyone has problems now and again, but since we're being careful not to name names, if it was the plastisol that you already know that some people are having trouble with bubbles, then you understood you were taking a chance in the beginning. I don't mean to be a smart a** but I think every vendor, no matter who it is, deserves the chance to make the product good. I know most vendors that if you're just completely dissatisfied with the product, almost always offer refunds. You should have contacted the vendor and if they didn't handle things to your satisifaction, then yes I myself would have probably posted about it. Every company deserves a chance to stand behind their product. If they don't do it, then that's a whole different ballgame. Also if it is the company that some people have had a problem with bubbles in the microwave, they offer free samples if you ask, I think it's only 8 ozs. but it should be sufficient enough for you to know if this is a product you want to use or not.

Largehead Louie Posted April 6, 2012 Report Share Posted April 6, 2012 (edited) Simple answer....Heated TOO FAST. I NEVER have bubble issues, but then I leave my microwave on 75% when heating. Edited April 6, 2012 by Largehead Louie Quote Link to comment Share on other sites More sharing options...
jeff@mf Posted April 6, 2012 Report Share Posted April 6, 2012 (edited) Let it set overnight without shaking or stirring, if the plastic weighs more than water the water will be at the top assuming water is the issue and vice versa if it’s a floating plastic. It looks like the perfect storm for it being water(mostiure) to me, or it is contaminated with another chemical by accident. Or it could be one of those freak things going on with the microwave, I have seen them go crazy and heat at extreme high heat more than once.

carolinamike Posted April 7, 2012 Report Share Posted April 7, 2012 Jeff, it's definitely not a moisture issue. For the cheaper microwaves that don't have heat settings it just doesn't work well. Works great in a Lee pot or Presto pot and microwaves that heat low and slow, but speed heating seems to produce microbubbles. But, if it is the company that people continually keep commenting about the microbubbles, the company has openly acknowledged that their plastisol is not for use with everyone's microwave and this same bubble issue comes up repeatedly over and over. That is the reason the company gives samples out for folks to try to see if it will work out for their application. Whether it makes bubbles, smells strong, has sediment in the bottom or is a little tacky when you take it out, but cures out fine after sitting overnight does not mean it's junk or bad plastisol. It just means it's not working in the application that you would like for it to. It always boils down to personal perference. Quote Link to comment Share on other sites More sharing options...

I’ve actually got an infection in my surgery area and still not up to par. The only reason I keep saying moisture as this is the only way I have seen any brand plastic do this is to have moisture in it, pretty strange. Bass 4.. OK, so it’s not moisture why not try another way of heating your current plastic, like a pan and stove top. This would help explain to me more about this product. I thought I have tried every brand of plastic, except CC but I haven’t seen so much foam before other than one customer kept his 55 gallon drum out in the elements and by water sprinkler and we stress to everyone not to get any moisture in any plastics, colors ect…… At this point I would call the person you bought it from, that would be your best bet.

Frank Posted April 7, 2012 Report Share Posted April 7, 2012 If I heat it fast it does that everytime. It is worse with harder compounds. If I heat in a presto it does not do this at all. To be real honest I just deal with it, but only if I am injecting. If I am pouring baits there are ways of skimming the top to get the bubbles off. Or just let it set and peel the skin off the top. If you are injecting suck up the plastic from below the bubbles. At the same time you will realize the bubbles clinging to the injector which helps out the rest of the plastic. This plastic does not do this on reheats which sound funny but it doesnt. Clear baits are a bit of a challenge with this plastic so just heat slower. All plastic have there ways about them.

Basscandy92040 Posted April 8, 2012 Report Share Posted April 8, 2012 I too have learned to deal with the same type of plastic. I heat at 50% power to start and I still seem to get them...but after putting it my lee pot they rise to the top in no time... Quote Link to comment Share on other sites More sharing options...
ROWINGADUBAY Posted April 9, 2012 Report Share Posted April 9, 2012 wouldn't a vacuum pump cure all of this if you pulled vacuum on heated plastisol ? Quote Link to comment Share on other sites More sharing options...
bass4cache Posted April 9, 2012 Author Report Share Posted April 9, 2012 UPDATE: This post was mostly to show what bubbles look like and it seems to have taken a different path. I could care less how to fix the problem with this paricular product but I decided to mess around with it a little more. Used less power and more time n the microwave. It helped a lot but still you get bubbles that will eventually disipate. It took about 5 times as long as Im used too. Like I said in my previous post this may be the perfect plastic for some, but as for me I'm going back to what works best for ME. Quote Link to comment Share on other sites More sharing options...

Frank Posted April 10, 2012 Report Share Posted April 10, 2012 Understandable, most would at least give it a try. But this is a learning board and most of us thought you wanted help, thus the reason you got such responces. Frank Quote Link to comment Share on other sites More sharing options...
