Fiber Matrix

Hi,  We're looking for a company that manufactures Fiber Matrix material to be used in an agricultural application.  The closest product I've been able to find it the roof ridge vent material made by GAF.  However, it contains aluminum oxide which can harmful to our application, and we can only purchase it in small quantities.  It has worked well for our tests, but we need to purchase this material in bulk.

Could someone point me in the right direction?  Thanks!
