Use of Metal Sulfides

Friction Materials Chemetall Ges.m.b.H. has been engaged in the research, development and manufacture of solid lubricants for the friction lining industry for many years. Specifically sulfides of various metals have proved to be the most versatile and effective additives for this application to reduce wear and comfort problems. These products are used by our business partners throughout the world as friction coefficient stabilisers and comfort additives. Especially for use in antimony-free friction linings, new solid lubricants based on synthetic sulfides such as tin sulfide were developed.

Lubricants Solid lubricants of Chemetall Ges.m.b.H. based on metal sulfides allow to improve the friction coefficient and the wear characteristics in lubricating greases, lubricating oils, lubricating pastes and bonded lubricants. Decisive progress can be achieved especially under extreme loads such as resistance to galling. Synthetic metal sulfides of Chemetall Ges.m.b.H. are suitable as substitutes for molybdenum sulfide.

Abrasive Materials Chemetall Ges.m.b.H. has been a world leading company in the supply of additives and filler systems for the abrasives industry for years. These active fillers are mainly used in resin bound grinding wheels and cutting wheels and decisively improve the grinding process and the grinding pattern. Our abrasive additives are mainly metal sulfides and complex chlorides which are suitable for all forms of grinding and cutting such as precision grinding, rough, cold and hot cutting.

Powder Metallurgy Metal sulfides of Chemetall Ges.m.b.H. are employed in powder metallurgy. Synthetic sulfides such as tungsten or tin sulfide as well as multi-phase sulfides in various particle shapes and sizes decisively improve the machinability of sintered parts. Sintered parts are used in high-performance applications where resistance under maximum loads and temperatures is demanded.

Plastics Solid lubricants of Chemetall Ges.m.b.H. based on metal sulfides can improve the coefficient of friction, abrasive characteristics, impact strength, modulus of elasticity and other mechanical characteristics in plastics. Especially for applications where dry operation is desired, high-performance solid lubricants prolong the lifespan and increase the tribological characteristics of plastics. Synthetic metal sulfides of Chemetall Ges.m.b.H. are suitable as substitutes for molybdenum sulfide.
