plastic turning yellow

Recommended Posts

I have had this problems also, made about 100 pearl white 5" senkos, put them away in a my tackle box, two weeks later they look like they chain smoked! I have also had this problem with trying to make large batches 2+ cups. Start off white, end up with ivory when were done. Temps never get over 375?

We also made a bunch of black skirts, worms and senkos. We bought a 55 gallon tank to test some prototypes. Calhouns color faded almost to white if they are left in over night. MF & Lurecraft no fading.

Del thinks I got a bad batch of plastic from Calhouns, the thing I am curious about is, if I got 2.5 gallons of hard plastic from the bottom of the 55 gallon drum, what did the other 52.5 gallons of plastic come out like for other customers :?:

If plastic is turning yellow and this is pretty much all plastics its generally because of over heating. Try A capful or heat stabilizer in what ever brand you are using.

Like senkosam said reheats are really prone to turning yellow mainly cause the stuff doesnt get stirred enough while heating.( its very hard to mix also)

if your going to remelt cut it up very fine and if you still have the problem add a very small amount of heat stabilizer to it.

I tried everything with Calhouns. Here was my process, from the original plastic we purchased that poured correctly. Maybe people could tell me what I did wrong:

1. Pour two cups of room temp (65-70) calhoun plastic into pyrex cup.

2. Heat in the microwave for 2 - 3 minutes, stirring every 45-60 seconds.

3. Once plastic turned clear (usually around 300 degrees) add color, 10 drops of heat stabilizer, salt, glitter and stir.

4. Heat in microwave for 45 seconds, stir and pour senkos.

5. I could usually get 2 pours in a 4 cavity mold without reheating.

6. The "funnel shaped" over poured plastic I would through back into hot plastic and stir, letting it sit for minute or two.

7. Reheat for 45 seconds stir and pour again.

When I lay the senkos on the cooling rack they start off pearl white and end up couple shades off, more like ivory, similar to what bradshaw is talking about. We even had a couple that were swirled ivory and white??

I thought like senkosam that this is the way it is, then we got samples of Lurecraft and MF and I personally have not had these problems with either of these. I am still using dels colors with lurecraft plastic so I am pretty sure its not the colors. I also tried just white, pearl powder and white, and various glitters. Anything with pearl powder was more prone to changing color but they all still changed.

James,

Keep in mind if you cook it very long ( like it a hot pot) that the heat stabilizer will burn off. same thing with reheating over and over.

I believe heat stabilizer burns (evaporates ) the fastest. so if your useing a hot pot and its sitting for a while you might want to add heat stabilizer a few times every 1-2 hours?

Del, have you been able to test the latest batch of Calhoun's plastic?

Any microbubbles or suds?

Any change from clear to amber over 350 degrees, on the first pour?

Softness pretty much like the original batches we got 2 years ago?

I still lean towards Calhoun's, but won't take a chance unless you or April tested it.

James:

What is the overheat temperature???? Did Calhoun's give you a number in degrees?? I'm curious as I am sure many should be.

I can say that I have some Calhoun plastic sticks from at least a year ago in pearl white and they are still pretty good...no significant yellowing or fading...

From what I have been told by both the company and users is that they can go just past 400? ,

375 being optimal. I never used a thermometer.

According to calhoun the heat stabilizers burn off first, so keeping it heated for a long time is not a good thing unles you add more stabilizer, this would go for any plastic BTW.

Ryan I dont think you need to worry, James buys it in bulk Direct and I am sure its a differnt batch number than what you recieved. But I did check to ease your mind. They will let me know in the AM.

Frank

Yes we had no problems with our last batch, we have more coming monday.

in the microwave

there are some slight bubbles just after it gels and they burn off when it gets to pouring temps. its pretty clear.

on the stove I dont have any problems either way and the plastic is alot clearer. this goes with any plastic its really nice cooked on the stove.

jmik26

you told me on the phone that you couldnt get it to pour thin, ie it was very thick, came out in clumps, so how did you pour stick baits with that? Like I told you on the phone there was only 5 people who got that problem and all was taken care of( franks buddy was one of them) so the rest of the drum didnt get sent out. Just thought I would let you know again incase you had forgotten our telephone coversation.

If your still using it to pour stick baits or have used it to pour stick baits then it obviously pours fine.

Please dont get me wrong, if there is plastic that isnt useable we will take care of it we always have and always will with any of our products, just like lure craft and m-f and the other companies selling products.

But when I read about these problems on the internet and no one says anything to me on the phone how the heck am I suppose to know what is going on.

its come down to one or 2 people bashing calhoun plastics, for what ever reason. These people wait 2-3 months to contact the seller, and will bitch up a storm on the internet before they even notify the seller.

Personally I dont care if you bash calhoun lure craft or m-f or anything else for that matter it makes no difference to me. If something is wrong with something we sell we take care of it.

what does tick me off is people who will tell half truths and not give out the whole story, Better yet not call and say HEY I HAVE A PROBLEM, but instead talk smack. Why I have no clue, maybe its to look cool in front of a few freinds, they didnt get there products fast enough, I couldnt make a custom mold fast enough for them and at there price range, I have know Idea and I really dont care, I think its about time Companies respond back to negitive stuff from buyers, why Other companies dont stick up for there products I could never understand. If something is bad most people know I am the first to say so if I have been told.

BTW out of 3+ years in doing this with 1000's of gallons sold,Less than 20 people we had to replace plastic too. less than 10 ever said they were unhappy with it. and only 2 keep on bitching on the internet but have yet to send me the bad plastic.

I didn't ask them about temp this time, but I will call them again tomorrow and talk about temp. I have had the pearl white start to turn yellow at 330 deg. I monitor the temp in the pot with a thermocouple, so I know that temp reading is accurate! I try to run at 300 to 320 if possible. The plastic is constantly stirred! They told me that if you had plastic before sometime last fall, then you could get the fading and yellowing from exposure to light. That's not to say that all of your pearl white baits are going to fade and or turn yellow. I have some that haven't turned yellow!

In the past Calhoun has stated to me that their plastic will take 350 deg

But remember most of the glitter and colorant doesn't like 350 deg for very long. The green, purple, copper and gold have been the most touchy with heat for me. I will post what I find out tomorrow!

Del, still have not received the email with address to send the plastic to :( But thats OK, I have taken my losses and moved on to a better product. However I feel a need to share this information with others that may experience the same problems, ie... 4 weeks to ship out "in stock orders", not contacting or responding to customers, sending bad products, posting on TU when paying customers are waiting for responses :censored: You choose to respond to TU instead of emails, so here we are.

If you look at your invoices, I had three 1 gallon purchases which poured fine, and one 2.5 gallon purchase that didn't pour at all. This purchase was in beginning of November, received the plastic in December :?: Holiday activities left me no time to pour, around January I started pouring again, noticed problem right off the bat, tried for one week to make it work but it wouldn't, then contacted you, now its been around 4 weeks.

My first statement in my post was "I tried everything with Calhouns. Here was my process, from the original plastic we purchased that poured correctly." So not only do I have 2.5 gallons of plastic I can't use, I have about 350 senkos that fade, turn colors, and are hard as a brick. Total money wasted around $250, it will take me forever to recover that!

If you look through the posts you will see that it is more then two people that complain. Del look at your own web site, people are complaining about lead times and products 8O I just don't understand why its so hard for you to believe your customers when they have problems :?:

I talked with Calhoun's sales rep and he informed me that yes the calhouns would be fine at 350 deg, but I myself never intentionally run it that high. If I can I will keep it below 340, because as most of you know a lot of the glitter we use doesn't like those higher temps for very long. Also the longer you have the plastic heating the more problems you will have with it starting to burn. Calhoun has added extra heat stabilizer to the soft hand pour plastisol to help with the prolonged heating of the plastic in the pot. If you are heating the plastic in a pot for more than 30 minutes then you should add additional heat stabilizer. The heat stabilizer actually vaporizes and takes the heat with it as the vapores exit the compound. Therefor additional stabilizer would need to be added. As I said before in an earlier post, Calhouns is now adding a UV inhibitor, to remove the fading or yellowing of the plastisol. Calhouns has been very good about standing behind their product. I hope this information helps you guys to better understand the characteristics of the plastisol we are working with. Also Just for the record, I was not posting here to bash anyone or any company! I was only trying to get to the bottom of a quality problem that I was having. And I appreciate all of the help that has been given here, if it wasn't for a lot of you guys I would have struggled a lot more with issues such as the one in this post.

I make a lot of clear baits using dels on a burner, I have never had a problem with them changing a shade ot two either on the burner or after storage, the only thing that tints them slightly is the scent put on them once they are bagged, if I leave the plastic on the burnewr ofr a long time it will eventually tuen a slight color.

I was wondering if anybody received there replacement plastic, if so is it better? I am trying to salvage the calhouns that I have, tried putting extra heat stabilizer in it with no luck.

In good faith I also tried adding extra softner to it, also had no luck. Can't see messing with something that should be so simple. I guess its the price that has me trying numerous things to make this plastic work.

Maybe somebody here could use it in a non color critical situation. Is this a plastisol that requires a color additive and hardener/softener. All the plastic I ever bought was premix so I have no experience with mixing. How much do you have and what would it cost if you were to sell it?

I could use some hard plastic for making masters so let me know...and how long of a shelf life does it have?
