Dow Corning siloxane
masterbatches and siloxane
powders can:
-
Significantly reduce friction
-
Increase the lubricity of molded plastics
-
Increase the mar and scratch resistance of molded-in-color electronic
components
These polymers also serve as processing aids:
-
Improve mold flow to permit the production of thin-wall housings for small
electronic components, for example.
-
Increase fire retardance of housings and components used in electronic
components.
Designers of components and formulators of materials used within the
telecommunications and electronics industries use siloxane masterbatches and
siloxane powders for a number of diverse applications. A typical application
includes gears that must function with little or no external lubrication. In
such applications, the ultra high molecular weight polymers improve lubricity
and slip, reducing the coefficient of friction in the gear assembly.
Pelletized formulations containing 50% siloxane dispersed in nylon, for
example, have outperformed fluoropolymers in side-by-side evaluations.
