Resins

文檔

Resins are convertible into polymers, and there are many different types of resins. Other materials that fall under the category of “resin” include acrylic, cellulose, and alkyds. Gel coat resins also exist, which are combinations of additives and base resins. Every resin has a unique purpose and properties that make it valuable across numerous industries. Most resins are flexible, versatile, strong, and resilient – making them important in manufacturing, automotive, construction, aerospace, and a number of other industries.

Common products that utilize natural resins include: plastics, medicine, flavors, aromas, varnishes and coatings, printing inks, adhesives, insecticides, insulation, and stimulants.

Synthetic resins have similarities to natural ones but with different chemical makeups. Synthetic resins and plastics are often interchangeable. There are two types of synthetic resins: thermosetting and thermoplastic. Thermosetting resins retain their shape permanently after the heating process. Thermoplastic resins, on the other hand, remain fluid after heat treatment and can undergo reshaping as necessary. Examples of synthetic resins include polyester, epoxy, and polyurethane.
