The properties of the insulating material are affected by which composition

We can not leave acetate cloth tapes in our lives, insulation materials in the harmful gases and wet dust and other conditions will be affected? Let's talk about the knowledge of insulating materials.
1. Resistance, resistivity:
   Resistance is the reciprocal of conductance, the smaller the conductive material, the greater the resistance, the higher the resistivity the better.
2. Sealing degree:
   On the oil, water quality seal cut off better.
3. Ignition resistance:
   People on the insulation of the fire resistance requirements are getting higher and higher, the higher the fire resistance, the better the security,
4. Resistance to arc:
   Insulation material of the surface composition of the electrical layer to determine the insulation of the arc-shaped material. The greater the time value, the better the arc resistance.
5. Tensile strength:
   Insulation material mechanics of the tensile strength of the most extensive, the most representative of the implementation.
6. Voltage, electrical strength:
   Insulation material breakdown voltage, the higher the electrical strength the better.
