LATAMID 66 H2 G/50-V0HF1: LATI’s proposal for metal and thermoset replacement in structural applications also requiring self-extinguishing properties.

Here is a new success for one of the most innovative compounds recently developed by LATI.

SELNI has chosen LATAMID 66 H2 G/50-V0HF1 for the manufacture of new brush holder arm used in electric motors, generators, and power transfer systems.

The arm is the seat of the conductive graphite element in charge of electric power transmission to the device.

The design of this component requires an extremely tough and reliable material even at a working temperature exceeding 100°C, for both obvious structural reasons and ensuring a continuous and constant contact between the graphite electrode and live parts.

Other aspects of equal importance in this particular project are the tracking resistance, which with LATAMID 66 H2 G/50-V0HF1 is 600 V, and the UL94 self-extinguishing level, V0 certified on thicknesses between 0.75 and 3 mm.

Dimensionally stable and easily convertible, LATAMID 66 H2 G/50-V0HF1 has been also chosen for its low environmental impact ensured by the formulation compliant to RoHS regulations and halogen and red phosphorus free.

The V0HF1 material is a perfect replacement for conventional brass components, which are expensive to manufacture due to the number of geometrically complex parts.

This material is also best suited as an alternative to thermosetting composites, which, by definition, are non-recyclable and problematic from the environmental point of view.

In this case, the V0HF1 proposal replaced traditional PA66 reinforced by 50% glass fibres, featuring red phosphorous as flame retardant.

A major issue was then solved, that is production of potentially hazardous compounds of red phosphorous after prolonged exposure to environmental moisture.
