What Are Polymers?

Polymers are large, complex molecules made up of repeating structural units called monomers. These materials have a wide range of physical properties and uses, making them vital in industries such as automotive, packaging, electronics, and healthcare.

Main Types of Polymers

Thermoplastics

  • Overview: Thermoplastics are polymers that become soft when heated and harden when cooled, allowing them to be reshaped and reused multiple times.
  • Examples: Polyethylene (PE), Polyvinyl Chloride (PVC), Polypropylene (PP).
  • Applications: These materials are widely used in packaging, automotive parts, and consumer goods.

Thermosets

  • Overview: Thermosetting polymers undergo a curing process that forms irreversible bonds, making them durable and heat-resistant.
  • Examples: Epoxy resins, Phenolic resins, Polyurethane.
  • Applications: Thermosets are used in electronics, adhesives, and coatings.

Elastomers

  • Overview: Elastomers are polymers with excellent elasticity, capable of stretching and returning to their original shape.
  • Examples: Natural rubber, Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR).
  • Applications: Used in seals, gaskets, tires, and flexible hoses.
