Abstract
The present invention provides an abrasion resistant composition comprising fluoropolymer and an effective amount of micropulp to increase the abrasion resistance of an article such as a film formed from the composition by at least 25% as compared to film formed from the fluoropolymer by itself. In an especially preferred embodiment, the composition also contains an effective amount of pigment to further increase the abrasion resistance of film formed from the composition as compared to film formed from the fluoropolymer by itself. The invention is especially useful for films formed on a fuser roll.
