Resins may be biological or synthetic in origin, but are typically harvested from plants. Resins are mixtures of organic compounds, and predominantly terpenes. Well known resins include amber, hashish, frankincense, myrrh and the animal-derived resin, shellac. Resins are commonly used in varnishes, adhesives, food additives, incenses and perfumes.
Mastic tears. Mastic (Greek: Μαστίχα) is a resin obtained from the mastic tree (Pistacia lentiscus). [1] It is also known as tears of Chios, [2] being traditionally produced on the island Chios, and, like other natural resins, is produced in "tears" or droplets.
Myrrh resin. Myrrh (/ m ɜːr /; from an unidentified ancient Semitic language, see § Etymology) is a gum-resin extracted from a few small, thorny tree species of the Commiphora genus, belonging to the Burseraceae family. [1] Myrrh resin has been used throughout history in medicine, perfumery, and incenses.

Rosin (/ ˈ r ɒ z ɪ n /), also known as colophony or Greek pitch (Latin: pix graeca), is a resinous material obtained from pine trees and other plants, mostly conifers.The primary components of rosin are diterpenoids, i.e., C 20 carboxylic acids.
Other fossil resins: burmite in Burma, rumenite in Romania, and simetite in Sicily. Other natural resins — cellulose or chitin, etc. Plastics used as imitations: [84] Stained glass (inorganic material) and other ceramic materials; Celluloid; Cellulose nitrate (first obtained in 1833 [85]) — a product of treatment of cellulose with nitration ...
Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
Many different kinds of resins may be used to create a varnish. Natural resins used for varnish include amber, kauri gum, dammar, copal, rosin (colophony or pine resin), sandarac, balsam, elemi, mastic, and shellac. Varnish may also be created from synthetic resins such as acrylic, alkyd, or polyurethane. A varnish formula might not contain any ...
