Made from mica splittings bonded with modified shellac or other resins. Moulding plates are rigid at room temperature but softens when heated at temperature between 100° to 140°C. They contain relatively high level of binder content to have necessary flexibility for easily moulding into any desired shape upon heating. On cooling, they will regain rigidity and retain the shape of moulded forms.
Application : Are chiefly used for the manufacture of commutator V-rings and cones, end-caps, channels, angles, bushings, decorative lamp shades, etc.
