Excel Biodegradable BBs - Our Favorite Click Here For More Info On Excel BBs

• Excel BBs hava 3 primary elements, Barium Sulfate, corn starch & a special patented synthetic bio-degradable plastic. Barium Sulfate is the weight component of the BB. For those of you who aren't familiar with Barium Sulfate. Barium is considered a soft non-toxic metal that belongs to the alkaline group, resembling calcium chemically. The form that people are probably most familiar with is it use as a radiopaque agent. Radiopaque, is most commonly known as the white milky stuff that doctors make people drink to use in stomach X-rays. This material is used in both the Bio & Standard BB. Corn Starch: is the accelerator component of the BBs. Once exposed to the elements over a period of time, bacteria attacks the corn starch which creates microscopic holes and tunnels in the BBs. This weakens the polymer matrix of the Bio-Plastic which helps the BB to break down. Bio-Plastic: is the filler component and is the heart of what makes the BBs bio-degradable. This plastic is mix with a special component called ECO3 made by the NOVON Japan Inc. It is a special material when combined with certain types of plastic, helps it to breakdown and make it edible to bacteria. So, how does it work? When the BBs are exposed to the elements, bacteria begin to attack the BB by feeding on the corn starch. This creates many tiny pits, holes and tunnels in the BB which weakens the polymer matrix of the BB. At the same time, exposure to the elements makes the plastic brittle, which in turn then breaks up into small particles. These smaller particles break down further, which are then digested by micro-organisms within the surrounding environment. Once this process is complete, no visible evidence of the BB remains. For more detailed scientific explanation of this process and independent verification by universities & testing labs from around the world proving that ECHO3 works, can be found at Novon's web site. http://www004.upp.so-net.ne.jp/novon/english1.html To review all the information at this web site, scroll down to the very bottom of the page and click on the "NEXT" icon to review all information. Excel has an exclusive agreement with the Novon Japan Inc. for the use of ECO3 in airsoft BBs. So, why did Excel decide to use a Bio-Plastic instead of more natural materials? The main problem with natural material is that they are generally unstable for use in BBs. This instability is useful in the fact that the BBs can degrade in a much faster time but this also causes the BBs to have a very short useful life. In many cases, other bio BBs once taken out of the bag usually have to be thrown out by the end of the day because they already started to degrade. Excel chose to use Bio-Plastic because is had a long shelf life and the BBs would not start breaking down right away even when temporarly exposed to the elements. I also allowed Excel to make a Bio-BBs that equals the performance of the Standard BBs.

• .20gram Excel Biodegradable BB's White

  
  Excel .20 gram white biodegradable BB's. The standard in airsoft bb's. Great value and quality BB's. Our 0.20g weight BB's are our most popular weight and are suited for all levels of airsoft use.

• .25 Gram Excel Biodegradable BB's White

  
  Excel .25 gram white biodegradable bb's. - For those players who are looking for that extra advantage in accuracy, most choose the 0.25g BBs. The heavier weight makes the BBs more stable in flight and thus more accurate. It is also less likely to be blown off course from wind and has better penetration power which can help you eliminate targets behind bushes and other vegetation. The only draw back is that the 0.25g BBs has a slightly shorter range compared to the 0.20g BBs because of their heavier weight.

Excel High Performance & Environmentally Friendly BBs

• When you purchase Excel BBs you are buying the best quality airsoft BBs in the world bar none.

The quality of this process guarantees that each BB is exactly 5.97mm. +/- .01mm. But there is more to this process than just being perfectly round. The material is equally important. Excel normal BBs are made with a special plastic so it will not chip or be easily dented or deformed. Furthermore, unlike some brand which use harmful materials such as lead, Excel BBs are made with inert not toxic material which make it safer for the environment.
