am bringing this debate over from the Sonic Foam thread because that thread was hijacked (yes Louise, this sometimes happens), and it really isn’t the proper place for someone looking for information later on to find the merit of the discussion, or more likely debate.
TDI= Toulene Di Isocynate
MDI= Methyl Phenol Di Isocynate
When ave you most likely used a isocynate other than blanks? Probably if you broke something and got out the Super glue.
Whereas there is huge and diverse use for isocynates, let’s keep it simple for starters and say that the debate involves the merits of MDI being more environmentally friendly than the big bad TDI that is purportedly killing all of us.
In the Sonic thread it is stated by an experienced shaped I know that TDI is killing all of us in the industry. I find that very interesting knowing that the statement was made by a fellow shaper (and now owner launching his new MDI, soy based blank company after earlier launching Homeblown Foam). Now this shaper has shaped thousands and thousands of TDI blanks, like myself, Terry Martin, Al Merrick, Rusty, Linden, Robert August, Greg Noll, Hap Jacobs, Wayne Rich, Yater, Bing, Brewer, Mike Daniel, Stretch, Steve Coletta, Glem Minami, Barnfield, Bruce Jones…well, you get the point.
Yeah, gazillions of TDI blanks, and guess what? We are still around. Do I have respiratory problems or am I shaping from a wheel chair with an oxygen tank?
Okay, so I hear about how great MDI technology is for the planet and the merits of the foam, and I’m open minded, so I get some soy based foam, I get some Cane foam, I put my hard earned money down on foam that my customers are relying upon ME to provide them the best possible product.
Well, to make a long story short…don’t worry, I promise there will be many other storiesfrom others on this thread to read…I’M NOT BUYING IT!
I do not believe MDI foam is as good as TDI based foam, and now any of you out there professing that it is will have to PROVE IT to me and quite a few others. The best results I had was with the Cane based from Ice 9, and some of the results were actually good. BUT, I also had some yellowing that I could not conclusively pin down to it being cane. The foam seemed to be less consistent than ‘good ol’ Clark Foam (TDI), and it didn’t hold a candle to the Walker Ice 9 Mowses foam…not for shaping and the strength to weight ratio of the Ice 9 Mowses kicked ass all over the Cane and Homeblown MDI foams.
So I guess the claims and postulating, ponitificating, and general gesturing will begin soon enough, but if I were advising a newbie what to do regarding foam, I would say this:
"Use an established blank company. Who? Someone who has been around consistently since Clark’s closure. Someone with a track record. Walker went to Ice 9 and they created Mowses…great foam…easy to shape, really good strength to weight ratio. Surfblanks. Midget Farrelly has been providing foam in Austrailia for decades…okay so Andrew is doing it here and the factory i south of Ensenada…big deal, good foam with lots of blank availability.
I don’t mean to slight other people that Greg Loehr or some others might suggest, but these are the folks that I have used and can honestly recommend. I won’t get into the EPS story here other than to say there are some very good suppliers and I will be submiting some utility blank designs to White Hot in the near future. So I guess that means I must feel EPS has a lace in the industry. Stretch knows where I’m coming from on that one.
But this thread is about TDI vs MDI, and so I just want to finish by saying that I personally do not give a flying shit that the foams I suggested above are TDI…they are BETTER THAN ANY MDI that I have used. Unless someone can prove to me otherwise, that’s my story and I’m sticking to it.
This isn’t spell checked, but you get the picture.
