Question:
Which of the following properties is not correct for silicones?
Which of the following properties is not correct for silicones?
Show Hint
Silicones are widely used in high-voltage insulation due to their high dielectric strength and thermal stability.
Updated On: Jun 5, 2025
- Bio-compatible
- High thermal stability
- Low dielectric strength
- Water repelling in nature
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding Silicone Properties
Silicones are polymers with Si-O-Si bonds, giving them unique characteristics:
- Bio-compatible: Used in medical implants, safe for biological applications.
- High thermal stability: Can withstand extreme temperatures.
- Water-repelling: Used as coatings due to hydrophobic nature.
Step 2: Evaluating Dielectric Strength
Silicones possess high dielectric strength, making them excellent insulators in electrical applications.
Thus, the statement that they have low dielectric strength is incorrect.
Conclusion
Thus, the correct answer is:
\[
\text{Low dielectric strength}
\]
