Particle Composition

Post by MegaMav »

When it comes to particle balls, rarely does the manufacturer disclose what exactly the particles are made up of.

I know back in the late 90's there were glass and rubber particles being used, which some damaged the lane surface.

Due to the lane damage, have particle balls changed in terms of composition, and what has the effect on ball reaction been?

Can you give some examples of bowling balls with different types of particles?

Thanks!

Yes there are different particles used in bowling balls from Mica flake, to proprietary particles that some companies use. Unless the company tells you otherwise, usually companies use one particle for their lines and then Mica flake for pearlized bowling balls.

Thanks for the reply, do you have some examples of materials used as particles?

Some would include hollow glass spheres, solid glass spheres and some other proprietary ones....

Glass? as in the glass of windows or glass as in fibreglass?

I ask because glass is quite brittle. Why don't the pieces of glass continue to shatter as we bang the balls? And Siliconcarbide doesn't really sand or abrade glass (as far as I know). Trizact is used/needed to "sand"/abrade window glass in cars.

I though the original (1998/1999) Brunswick and Ebonite "particles" were of some other very hard substance?

Glass spheres, that's all we really know about it but I will say this. USBC did studies looking at the effect of particle on surface roughness found here that I did while there.
http://www.bowl.com/news/xmlburner.jsp? ... rmance.xml

It shows that some particles will even out surface roughness meaning the effect will be more gradual than with a normal solid reactive coverstock will mean. Meaning dull, it will perform pretty much the same as it does at 2000 or 4000 abralon.

Read that article it says a lot!

I remember hearing something about hard particles and soft particles that compress on the lane, creating a larger footprint on the lane.

Is there any truth to these old soft particles?

Meh maybe put its also incorporated into the morphology of the particle, how it fractures ect....most people still only use one kind of particle.

I know Legends/Lanemasters had been using industrial diamond dust in their particle balls for a time, and then moved to a smaller carbon based particle. I've heard many stories about ball drillers who hate to see someone coming w/a lot of LM particle balls.

I believe that L/LM had to either change fillers or cop to not using "diamond dust" per the Mohs' hardness specification for particles in the cover stock of a bowling ball circa 2005.

Correct, but the majority of their balls are still two piece construction....

Okay. I have been wondering what the difference between Pearlized and Solid coverstocks was. I had always been under the impression that there were basically 5 types of coverstocks: Polyester, Polyurethane, Solid Resin, Pearlized Resin and Particle. Is that an accurate summary?

I've also heard of hybrid coverstock. What would their composition be? I assume they're coverstocks between Pearl and Resin, but would that not make them Particle, if that is the case?

Thanks for the vote of confidence Mr Pinel, to answer the question however..

Pearlized coverstocks are the same as solid coverstocks with the addition of Mica flake which is a particle that fractures only in one direction. The Types of coverstocks are the following:
  • Polyester
    Urethane
    Solid Reactive
    Reactive with Particles
    Epoxy


Those are all the unique chemistries. But remember looping all particle balls in a category though is misleading since every particle provides a unique reaction!
I can Bold too!

Epoxy? You have my attention...

Would the C.System line fit in the Epoxy category? Where in the "reaction" spectrum would Epoxy fit, or would that be a similar situation as particle? I had always wondered what they did to solid covers to make them pealized. Now I know. :)

AFAIK, the Columbia EPX, versions T1 and A1, were the only two epoxy balls ever released.

Ask 10 bowling geeks about the EPX and be prepared for 20 different opinions. Talk about love/hate! Guys who owned them swear they "hooked on ice" but the ball suffered from cracking issues which lead to its demise. Popular "rumor" seems to be that epoxy technology wasn't quite ready and Columbia rushed the release.

The CSystem is reactive with particles, and each particle provides a unique reaction.
