Technical Data Sheet

MATERIAL SAFETY DATA SHEET (MSDS)

Application:

SW-COMMUTATOR M & P sheets are hard, dense mica plates used in segments, separators and spacers. They exhibit good electrical & thermal properties and mechanical strength. SW-COMMUTATOR M & P sheets can be sawed, sheared and punched into customized shapes. Its superior uniformity enables automatic feeding and stacking within high speed assembly operations. SW-COMMUTATOR M & P sheets are used within a wide range of small and medium size commutators for all kind of household applications, industrial equipments and power tools.

Composition: SW-COMMUTATOR M & P sheets consist of minimum 90% Muscovite alternatively Phlogopite impregnated with a specially developed epoxy resin.
Supply form: Thickness: 0.20 – 2.00 mm
Size: 1000 mm width, 600 mm or 1200 mm lenght
Customized strips or punched parts according to customers’ drawings and/or requirements.
Processing: SW-COMMUTATOR M & P sheets can be easily punched, or sheared. Tools for punching precise parts should be provided with spring loaded hold-down plates.
