What is that you do with this material?
Well you may or may not have heard of this hobby... its called "Airsoft". Which is in practice similar to paintball... SIMILAR.... The primary difference being that the guns used are 1:1 replica's of real firearms. Some are simply spring powered, some are electric and spring powered... others are "gas powered". The projectiles are bbs made of polystyrene and a biodegradable adhesive.
You fill a reservoir in each magazine with gas... there are three main gasses used, depending on where the GBB (Gas Blowback) pistol is made. One is CO2, but the replicas that use CO2 are not the best quality, then there are the models that use HFC134A, which is lower in pressure and power than Green Gas... then there is Green Gas.
Guns made in Japan are designed for use with HFC134A
Guns made in Taiwan (usually cheaper than Japanese models) are designed for use with Green Gas
Guns made VERY cheaply in Taiwan, Korea or China are designed for use with CO2.
So what this means is... the gas is released in small quantities with each shot, by a valve activated by the trigger mechanism. The chemical reaction caused when the semi liquid pressurized gas hits air behind the bb causes more pressure to build pushing the bb out the barrel.

He has the scans on his site, however.. he currently has his site "down for maintenance" So I could not find direct links to the scans.
The problems is though, I could not say with certainty that this guy actually tested green gas... and even if he did, he may have tested ONE brand of green gas... or tested several and picked one that was actually propane or CONTAINED propane. There are many brands.
What I still wonder though, I myself, and several others have brought this issue up to the EPA... last year, and yet the green gas is still being allowed to be imported. If it truly IS propane, then its being shipped in unsafe containers. Green Gas cans are NOT designed to hold the pressure of propane.
This is really no "skin off my back" because I use a Japanese made replica... but I want this argument to finally be over.
