Polymer used in making capsules

Options

A. Poly glycolic acid
B. Poly lactic acid
C. Nylon-2-Nylon-6
D. PHBV

Answer

To determine the polymer used in making capsules, we will analyze the given options one by one:

1. **Polyglycolic Acid (PGA)**: This polymer is primarily used for post-surgical devices. It is known for its biodegradability and is often utilized in sutures and other medical applications, but not specifically for making capsules.

2. **Polylactic Acid (PLA)**: This polymer is widely used in biomedical products, including drug delivery systems and tissue engineering. While it has applications in the medical field, it is not the primary polymer used for making capsules.

3. **Nylon 2 Nylon 6**: This polymer is mainly used in the textile industry for making fabrics. It is not suitable for making capsules, as it does not possess the necessary properties for such applications.

4. **PHBV (Poly β-hydroxybutyrate-co-β-hydroxyvalerate)**: This polymer is specifically mentioned as being used for the preparation of capsules. It is a biodegradable polymer that can also be used for capsule preservation.

Based on the analysis of the options, the correct answer is:

**Option 4: PHBV (Poly β-hydroxybutyrate-co-β-hydroxyvalerate)** is the polymer used in making capsules.
