Polypropylene is regarded as one of the lightest and most versatile polymers. It is capable of undergoing a wide array of manufactured processes, such as injection moulding, general purpose extrusion, extrusion blow moulding and even expansion moulding. Although existing in three different tactic forms, commercial polypropylene is typically a mixture of 75% isotactic and 25% atactic. Demand for polypropylene is rapidly on the increase19 and consequently, it is one of the most common types of microplastic found in the marine environment.

Explanation:

Polypropylene:
Polypropylene is a lightweight plastic material that is commonly used in a range of applications, including packaging, textiles, laboratory equipment, and automotive components.
