Final answer:
Polyethylene (PE) and Polypropylene (PP) are thermoplastic polymers commonly used in packaging and various other applications. They are derived from petrochemicals and can be recycled to minimize environmental damage.
Step-by-step explanation:
Polyethylene (PE) and Polypropylene (PP) are both types of thermoplastic polymers commonly used in various applications. Polyethylene is the most common plastic and is primarily used in packaging, such as plastic bags and containers. It can have different properties depending on the length of the polymer chains.
Polypropylene, on the other hand, is used in rope, binder covers, plastic bottles, and non-woven fabrics. It is produced from the monomer propylene via chain-growth polymerization. Both polyethylene and polypropylene are derived from petrochemicals and are not biodegradable, making them candidates for recycling to minimize environmental damage.
