Heat removing plasticizers from bowling balls?
« on: February 22, 2008, 01:21:48 AM »
A while back, I used hair dryers, heat lamps, hot water, and ovens to extract oil.
I did experiments on a couple of NIB balls, that had never touched a lane.

Found that heat lamps, hot water, and hair dryers, ALL made something come out of the ball. Some balls released more liquid than other.
Thought that it couldn't be OIL, so guessed that it was plasticizer.

Do you think bleeding out plasticizer is a problem?

Yes. It is what turns urethane into reactive resin.

So when you leach out the plasticizer you end up with a urethane ball (of sorts, w/a strong core)?

This is an interesting topic. If it is plasticizer, is it left-over plasticizer that is not needed?

No.  Heat eventually kills reactive bowling balls, whether it is friction from throwing the ball or heat from baking.  Adding "baking" to friction just accelerates the process dramatically.

This topic has been discussed in the past and if I remember correctly, it is said that bleeding out the plasticizers will weaken the ball drastically and start reacting like the urethane base. There is a safe way to bake a ball to extract oil only. I believe the heat has to be controlled and can not get over 135-145 degrees. I could be wrong on those exact temperatures though.

as someone who has used brunswick bowling balls since 1995 i firmly believe in the methods of oil extraction that they recommend for their products. i regularly use the rejuvenator to extract oil from the ball and the ball keeps it's "like new" roll and performance. i wouldn't even think of using another method to extract oil from the ball. it's not worth the risk.

Although I don't doubt what Duke's experience is, years ago when our shop first got the Revivor we put two new bowling balls in for 4 hours without anything coming out - not anything!
 
It may affect some coverstocks differently than others, but I agree with Greg Hoppe on this one. Brunswick actually recommends the process for their coverstocks. We've been putting every brand imaginable in it over the years with positive results. You choose. Try the process, or keep on buying new balls prematurely.

What happens to the ball when it soaks up enough oil that it isn't working well anymore? It sits in a locker, and gets replaced eventually... What have you got to lose if the ball is "dead"?  Are you afraid to kill it more?

A Pro Shop here in Sweden did the same thing for about 8 hours and nothing came out..

Its b/c those revivors are set to temperatures that are within safe standards. Using other methods like hair dryers and heat lamps put to much heat on them. Not to mention they heat the ball unevenly. A revivor or bucket of hot water would heat the ball evenly. You would just have to keep the water temp within a safe range.

Totally agree.  I think the max temp to only get oil out of the ball is 150-160 degree's.  Not exactly sure about the temp but remember reading about it.

I use the HOT WATER BATH method and have great results from it.  I'm sure the revivor would work really good as well.  It's just a lot cheaper for me to use hot water at my house.

USBC did a test on this, they tested the liquid coming out of the ball. It was something like 99.995% lane oil.

Doesnt say to much, if we dont know the amount of plasticize in a bowling ball, those 0.005% can be a big amount..
The Platicize may sweat out of the ball if the temp is above 60 degree celcius. A rejuvenator proabaly >50 degree C, so the plasticize wont be extracted.
Have anyone tried baking a Nib ball in temperatures above 140F/60C? I bet something will extract from it.

Th theory goes that if you keep the temperature below 150 degrees Fahrenheit, it will be lane oil that is removed. When you go above 150 degrees, it is plasticizer that comes out.

I have a total nv with 1000 games on it. I rejuvenate it with heat sometimes for 2 to 3 hours to get all the oil out of the ball. Give it a fresh surface and the ball is like new again. If you watch how its made you will see that they put the balls in a huge oven to cure the resins. Why would they do that if it would cause harm to the ball. Yeah you cant be stupid and put it in a 200 degree oven or something like that or even get it a 100 degrees then dunk it in cold water or take it out to your car and let it sit in the cold it will prolly crack just use your brain and it will be fine. I have actually put nib balls in to see what would happen and nothing at all came out period.

Interesting topic and experiment.  I have wondered about this myself.
