    Default Bubbles in plastisol


    Still very new to making my own baits and am having a problem with air bubbles in the plastic. I heat it in a Pyrex cup in a microwave. I've tried slow heating anywhere between 15 and 30 second intervals to 1 minute intervals. I don't use a thermometer I just eyeball it until it gets to a viscosity I want to shoot. But it doesn't seem to matter as the bubbles appear well before it's ready or even close to 350. I make these in my garage with the door open and live in central IL so whatever the temp and humidity is outside is what it is where I'm making. Anybody got a solution I could try?

    for you beginners getting into plastic you never ever want to shake a gallon of plastic if you have to pour it out into a different container and use a metal rod to mix when you put it in the microwave do not over mix it and if you are getting bubbles heat in a short period of time what's the time the bubbles will come to the top and and burst I will not get into different companies of plastics this is unfair to them I use a wide variety from different companies and they are all different one way or the other . So you'll have to decipher which is better for you by a small a quality from each manufacturer and try it out for your self.

    Posting a picture of a water cooler that I put my plastic in that way you can stir without putting too many bubbles you can get the coolers in different sizes I believe this one here is a 3 gallon and you'll notice a button down at the bottom of the cooler for to get your plastic out into your Pyrex cups it makes it real handy.
