It almost always comes down to money as the chief reason... |

Perhaps. Celluloid table tennis balls have been around since 1901. Don't know why all of a sudden they're a problem and certain people have to make up a fake worldwide ban to justify moving to an inferior ball. I've yet to see a ball burst into flames in the middle of a table tennis match.

I would not be surprised that the new ball will eventually cost manufacturers a LOT less to make in the long run than the traditional 2-piece ball... So imagine charging the same to the public for something that will cost a lot less to make, hmmmm... |

I'd rather they ban Cellulite. |

The noticeably different bounce properties don't look promising. |

Worked for me except for one thing...I couldn't understand anyone but Adham....correction...I don't think I've ever really understood Adham either Were they saying the plastic ball bounces longer than the normal ball? So while the world is banning cellulose (presumably for its flammability), India is now exchanging Asbestos for Cellulose in their housing materials!!! http://banasbestosindia.blogspot.com/20 ... place.html |

Wooden table tennis blades are flammable too. Also the ITTF Handbook is highly flammable. |

Did a little searching myself and while any actual articles on a ban on cellulose are not apparent, I did find some chatter on car paint forums back in 2006 and 2007 talking about it (in the UK I think). Seems cellulose was banned in paint after 2008, cellulose having been stopped in manufacture around 2006 (not sure if this is UK only). Here are the links to the discussions I found so far: http://retrorides.proboards.com/index.c ... read=12592 http://www.driftworks.com/forum/technic ... paint.html |

I find fire danger a poor excuse. I know of not one fire "caused" by ping pong balls. They do not self ignite. I have had some in a car in the sun that got VERY hot and they did not light. While 12 ping pong balls caught in a fire would flare up for a few seconds, they will not be the "reason" for a fire. A small can, 4 ounces of paint thinner, nail polish, some paints or thinners would cause hundreds of times the release of energy of 12 ping pong balls. Some things "will" self ignite, like a linseed oil soaked rag. I have seen this myself. Linseed oil has not been banned by the world governments. ( I banned it's use in a large company after two fires in the machine shop) No one knows what the new material is going to be. Most plastics burn. Most give out much more heat than celluloid when they burn. Maybe they will add a fire retardent to the plastic. If the new balls do burn, what is the difference between the old and new material if neither has caused a spontanious fire since 1903? Since the ITTF has been talking about changing the ball since 2003, I think the ban they talk about is a smoke screen again for something else. I really don't care if they come up with a new ball if it is not alot more expensive. I don't care if it bounces higher. I don't care if the speed of the ball is similar to the old. No seam will be nice, that is where most cracks start. What I am concerened with is if the cost goes way up. I have been supplying balls for a grade school and a college at "my cost". Maybe the new methods of production will allow cheaper costs, maybe, but there is going to be new equipment required. We will pay for that at first. Wish I could get my hands on some of the new balls, (and the real reason to change). |

While not totally explaining the reason for switching away from celluloid, this webpage does have some interesting info on it: http://www.lashingguitars.com/celluloid/care.html I think the most interesting thing it says is celluloid is not illegal, just obsolete for just about everything but guitar picks and ping pong balls. Perhaps having found a way to make ping pong balls from a different substance has now just rendered it obsolete for this too? |
