The term “polymer” refers to a large class of materials made up of long chains of repeating molecular units called monomers. These materials can be natural or synthetic and are characterized by their unique properties, which can vary widely based on their chemical structure and composition. Here are some common types of polymers:
1. Natural Polymers :
Cellulose : Found in plant cell walls, used in paper and textiles.
Proteins : Made up of amino acids, found in living organisms (e.g., silk, wool).
Natural rubber : Sourced from rubber trees, used in tires and elastic products.
2. Synthetic Polymers :
Polyethylene (PE) : Used in plastic bags, bottles, and containers.
Polypropylene (PP) : Commonly used in packaging, textiles, and automotive parts.
Polystyrene (PS) : Used in foam products (EPS) and containers,it can be recycled by EPS granulator.
Polyvinyl Chloride (PVC) : Used in pipes, flooring, and electrical cable insulation.
Polyurethane (PU) : Used in foams, elastomers, and coatings.
Polytetrafluoroethylene (PTFE) : Known as Teflon, used for non-stick coatings.

3. Elastomers : These are flexible polymers that can stretch and return to their original shape, such as natural rubber and synthetic rubber.
4. Thermoplastics : These polymers can be melted and reshaped multiple times, such as polyethylene and polypropylene.
5. Thermosetting Plastics : These polymers harden permanently after being shaped and cannot be remelted, such as epoxy and phenolic resins.
Polymers are widely used across various industries due to their versatility, durability, and ability to be engineered for specific applications.
