Products Description
Insulation Diamond Dotted Paper is made of insulation paper coated by modified epoxy resin in the shape of rhombus.
In the process of coil drying,the agglutinating and solidifying of DDP can bond the coil into a fixed unit.
The bonding strength of epoxy resin is sufficient to prevent the displacement of the various layers of the winding in short circuit condition and further ensure the long-term mechanical and electrical properties of insulation structure.
Glue type: B-stage epoxy
Initial viscosity: non-sticky, only sticky after the motor is heated and melted
Curing conditions: 100 degrees Celsius
Bond strength: after heating, the layers form a solid structure to prevent the coil from loosening
| Components | Explanation | Influence on Thermal Endurance Class |
|---|---|---|
| Base Material | Generally high - quality electrical insulation paper | The heat resistance base determines the stability of the paper |
| Diamond Glue - dispensing Layer | B - stage or F - stage epoxy resin, in a B - stage semi - cured state | It cures after heating and provides bonding force |
| Composite Structure | Single - layer or multi - layer structure | The thermal endurance class can be improved through multi - layer compounding |
