Plastisol turning orange?????

[JOHN62]

I'm trying to make a super translucent pink tube. By the 2nd melt it was orange. I'm using CC plastisol and florecent pink. How do I keep it pink?  Thanks!

Use heat stabilizer and try keeping the temps down

I did the same before I used the heat stabilizer, I put some in when I make the color and then again if I'm reheated after it has cooled.

What temperature are you heating it to?

Pink turns orange when you overheat it.  Heat for shorter intervals and stir.

I'm heating it to 350     
4oz plastisol   1st heating 111 seconds, 2nd 33sec., 3rd on 22 sec. in microwave w 700watts
Heat stabilizer:  How much?  drop, squirt?

[Botanophilia]

First heating is probably way too much.  Haven't checked the wattage on my micro, but it's ancient so I doubt it's more than 700 watts.  My first heating is a minute at the most.  I use 6 or 7 drops stabilizer in 4 oz.  It isn't absolutely necessary, I worked with it for over a year and learned very well how to not burn plastic.   But it can save you if you accidentally heat longer than you should or if a color heats up faster than you expect.  Usually 1 min, 30 sec, 20 sec if it's fairly warm outside.  This time of year with the cold, it's more like 1 min, 30 sec, 30 sec, 15-20 sec.  Stirring between each interval of course. Usually I'll add my glitter before that last 15 sec.  I usually work with 4 or 6 oz batches, but even 2 oz batches will get about the same treatment for heating.

Bringing light colors to temp. slowly, and stirring in between, is important along with the addition of stabilizer.  Adding a small amount of new plastisol to reheats of light colors also can be very beneficial.
