I have only seen it from Quilter's Dream. I used it and LOVE IT. The batting seemed to be more even in texture, did not have any bearding or lint from it in my machine.
It is less flammable than polyester or cotton batting. Where I live, we can burn trash. Whenever I need to make sure to get a good fire going I get my trash bin from my quilting. That goes up FAST and burns a long time.
When we got the recycle batting we did a burn test. When the recycle batting burns the "waste" is a very fine ash. There are some minute hard particles in the ash but it did burn MUCH slower than polyester, cotton/poly blend or cotton batting.
