Hot Moulding Mica-Alkyd Vinyl

01-96 Alkyd Vinyl Mould Plate

Composition

01-96 mica moulding plate is a hot forming plate conforming to NEMA grade 2. Alkyd Vinyl resin binder in 01-96 is partially cured, it will soften under heat and facilitate good moulding. There are many different grades of 01-96 available depending on the type of mica used, binder content, surface characteristics etc.

Applications

For hot moulding of intricate parts, such as mica commutator cones, end bell insulation, slot cells, coil forms, tubes etc.

Processing

The layout consisting of the required number of layers of thin mica moulding plates (cut to definite shape), is set in a pre determined pattern. It is then heated uniformly to a temperature of 160°C – 200°C, till it becomes soft. It takes the required form when moulded under pressure. It
retains its form when cooled under pressure. The duration, temperature and pressure will have to be determined by application. These moulded parts, if required, can be fully cured under heat and pressure for several more hours to develop their full properties.
