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:
\[
\text{Low dielectric strength}
\]
