Resin vs. Polymer: What's the Difference?
Edited by Harlon Moss || By Janet White || Published on January 21, 2024
Resin is a natural or synthetic compound often used as a base for plastics, while polymer is a broad category of macromolecules formed by linking monomers.
Key Differences
Resin can be either natural, derived from plants, or synthetic, created through chemical processes. Polymer refers to a larger class of materials that includes a variety of substances formed by linking smaller units called monomers. While all resins are polymers, not all polymers are resins.
Natural resin is typically secreted by plants and is a complex mixture of compounds, used historically in varnishes and adhesives. Polymer, encompassing a wider range, can be natural like DNA or synthetic like nylon. The diversity of polymers exceeds that of resins, covering a vast array of materials with different properties.
Resin in its synthetic form is used in the production of plastics, adhesives, and coatings, prized for its adhesive properties and durability. Polymer materials, which include synthetic resins, can vary from flexible to rigid, with applications in everyday items like plastic bottles to high-tech applications in aerospace. The versatility of polymers encompasses a broader spectrum than resins alone.
When used in manufacturing, resin often refers to a viscous substance that hardens into a solid form, utilized in composite materials or as a binding agent. Polymers, by contrast, can exist in various states - solids, liquids, or gels - and their properties are defined by the types of monomers used and the nature of their bonding. This makes polymers more diverse in terms of physical states and applications.
In terms of chemical structure, resin can be a complex mixture of organic compounds, often with an amorphous structure. Polymer structures, on the other hand, are characterized by their long chains of repeated monomer units, which can be arranged in various ways to create different types of polymers. This structural difference underpins the varied applications of polymers compared to resins.
