Crystal Clear Plastisol Issue?
« on: 12/20/14 14:33 UTC »
We had an issue with our last 20 gallons of plastisol.  The best way I can describe the issue is the baits look splotchy.  Some areas are shiny and others are very dull and almost sticky to the touch.  I will explain what we do when injecting.  All plastic is rotated and mixed before adding colorant.  We heat up the plastic to 365 degrees and stir thoroughly. We then inject the baits and lay them on a table to cure.  After about 24 hours the baits start to change the way they look and after 48 hours are very splotchy.  It would seem like they are not being heated enough but the plastic is being brought up to well above 350 degrees.  We will have an occasional batch that turns out good and consistent as far as being shiny and not tacky.

This happened on the last 20 gallons (regular) so we moved to another company for the last 80 gallons of plastic.  Now I ordered another 10 gallons of CC plastisol to see if it was any better and we are having the same issue.  What I have noticed since the issue started is this plastisol has very few bubbles.  There were always less bubbles than other plastisols but these last batches with the issues have ZERO bubbles and shot great.  Only problem is when they cure they look horrible.  I have some soft plastisol from about a year ago that I go through the same process and it cures perfect every time so I know something is up I just can't figure it out.  We are on the West Coast and the temp has been in the 60s.  It was the same in the summer when it was 80 degrees outside as well.  Any ideas?

Any pictures that show the splotches on the baits? Perplexing....

Haven't experienced this. Is your thermometer reading correct???

I will take some pictures tomorrow and post them.  I have two thermometers and both are reading within a few degrees of each other.

My first thought is that the plastisol isn't getting mixed well enough before heating.  The crystal clear needs heavy shaking to mix well in my experience.  Maybe someone else will have other thoughts.

The new essential series settles more but seems to mix up better.  Give it a try when you order plastic next.

Here are a couple of images showing the issue.  You can see in the first image how the worm is shiny and smooth towards the front but lower down on the worm you can see it get a matte look and its no longer shiny.  Its hard to capture with a camera and the sun won't come out so that doesnt help the image but I think you can get the idea.





Like I said before I have soft CC from about a year ago that works great and stays nice and shiny.  The medium I have has this issue.  We shake the box and rotate it many times just like we have always done and heat it to 365 degrees.  It would appear that something has changed recently.  Any other ideas?  Thanks.

I can see the place you are talking about.

If you do a full batch, do they all look that way? Is there a pattern to where the "splotch" shows up?

If you put them in a bag with worm oil does the splotch go away?  Stay away?

i would also wipe down the mold really well with worm oil to see if somehow the finish on that part of the mold looks different.

Do you get the splotch with all colors you make?

I was going the same place Andy. I was thinking the mold cavity.

This was just one of about 300 worms from 15 different molds in three styles.  They all have a similar look.  Some batches are completely cloudy.  The problem we have is we use a lot of bright fluorescent colors and if we heat it up much higher than 370 degrees we have issues with the color changing or yellowing.  Not sure what else I can do unfortunately.  Do it asked for a lot number the last time I had the issue but never replied with any info or it others where having similar issues.

The color change is predictable for every fluorescent color. I used to my flo bubblegum and cook it enough to get a "dreamsicle" color. Kinda pink but plenty of orange. All manufacturers colors will do that.
Seems this is some type of plastic issue. Do-it will get it I imagine.

If some are completely cloudy that really points to the plastic did not get hot enough...what kind of thermometer are you using?

Or...The plastic was not mixed well...once...and now you working with a box with wacked chemistry. That happened to me with a gallon of another plastic that I thought it was mixed well enough (just got it in the mail!) ...it looked ok...but the baits I made were terrible. Cloudy and sticky and super soft.

I let the plastic sit until two days later and I noticed that it had completely settled into 3 layers. I ended up throwing away the gallon of plastic because I had altered the chemistry on the first use!

Do you take the box off so you can see the plastisol Andy?

Most don't remove the box so it is tough to see if the plastisol is mixing completely. I saw some residue sticking to the plastic bag more than I thought when I used the CC. Caused me issues for sure as a result of inadequate mixing.
