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
Generally,we use 20kg's bag or 500kg's bag to load the mica.
15 tonnes can be loaded into one 20FCL?
?
?
Packing: 25kg/Bags or 50kg/Bags or 1Ton/Bags or as Customer requirement
