Answer the following questions :
Why is teflon used as a tape for sealing purpose?

Explanation

### Step-by-Step Solution:

1. **Understanding Teflon**: Teflon is a synthetic polymer known for its unique properties. It is a type of fluoropolymer, which means it contains fluorine atoms in its structure.

2. **Properties of Teflon**: Teflon has several important properties that make it suitable for sealing purposes:
- **Chemical Resistance**: Teflon is resistant to many chemicals, which means it does not react with substances it comes into contact with. This is crucial for sealing applications where chemicals might be present.
- **Non-Stick Surface**: Teflon has a very low friction coefficient, which gives it non-stick properties. This means that substances do not easily adhere to it, making it easier to maintain seals.
- **High Temperature Resistance**: Teflon can withstand high temperatures without degrading, making it ideal for applications where heat is a factor.
