Mica's main advantages are insulativity and heat resistance, which are perfect:
1). If mica's thickness reaches 0.015mm, its average breakdown voltage would be 2.0—5.7kV, puncture strength would be 133- 407KV/mm.
2). When mica is heated by temperature of 100-600°C, its elasticity and surface properties will not change.
4. Packing&Loading
