Potting component is highly dielectric materials and is generally used in electronic and electrical devices which provide electrical insulation and protection against harsh environmental conditions such as moisture and fire flames. Whereas encapsulation is a method of assembling an electronic device with a solid compound to protect against corrosion, shock, moisture, and vibration. They are majorly used for various applications in electronic and electrical industry and these devices have capability to work under heat, stress, and attain a low outgassing performance.
