Abstract
A non-asbestos friction material is made by molding and curing a composition primarily comprising a fibrous base excluding asbestos, a binder, a filler, and at least three metal sulfides excluding titanium sulfide, complex metal sulfides and being free of antimony and lead compounds. This friction material has minimized metal catch and improved wear resistance, both in the high-temperature region. Absent lead and antimony compounds, the friction material is friendly to the environment.
