Any of numerous clear to translucent yellow or brown, solid or semisolid, viscous substances of plant origin, such as copal, rosin, and amber, used principally in lacquers, varnishes, inks, adhesives, plastics, and pharmaceuticals. in (rĕz′ĭn) n. 1. In polymer chemistry and materials science, resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. A.W. It possesses higher mechanical properties and more thermal and chemical resistance than other types of resin. Natural resin is produced by most plants and is a thick, sticky fluid. Types of chemical resin include plastic resin, acrylic resin, polypropylene resin, and melamine resin. Mei, in Comprehensive Medicinal Chemistry II, 2007. Chemical resin is a term used to describe synthetic resins. 2.12.17.1.2 Macroporous resins. Phenolic resins are divided into two different types, novolacs and resoles. Plastic Definition and Composition . Macroporous resins have been used for many years in ion exchange applications, as polymeric adsorbents and for reverse-phase chromatography purifications. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange.It is an insoluble matrix (or support structure) normally in the form of small (0.25–0.5 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate. Plastic is any synthetic or semisynthetic organic polymer.In other words, while other elements might be present, … The resin itself is composed of organic polymers that form a network of hydrocarbons. Epoxy resin has many industrial applications for a variety of purposes. Resin definition, any of a class of nonvolatile, solid or semisolid organic substances, as copal or mastic, that consist of amorphous mixtures of carboxylic acids and are obtained directly from certain plants as exudations or prepared by polymerization of simple molecules: used in medicine and in the making of varnishes and plastics. Resins are usually insoluble in water. Polymers basically according to their sources can be divided into: 1- Natural polymers 2-Synthetic polymers 3- Semi-synthetic polymers; These types of polymers formed by chemical reaction with neutral polymers. What is resin material made of? Czarnik, H.-Y. Phenolic resins are found in a myriad of industrial products. Not a chemical reactant in and of itself, IX resin is instead a physical medium that facilitates ion exchange reactions. Both have high temperature stability up to 300° – 350° C, high water and chemical stability. Different types of resins exist depending on their chemical compounds which define its properties: silicones, epoxies, acrylics, alkyds, and more. The simplest definition of a polymer is a useful chemical made of many repeating units. Cation-exchange resin definition is - an ion-exchange resin that contains acidic groups for exchange cations. 2. The similarity between chemical resin and natural resin is that they both harden. See more. Phenolic resins are often dark-colored from yellow to dark red, and have an excellent price/performance profile. These resins react either with themselves in the presence of catalysts, or with many co-reactants like amines, phenols, thiols, etc. Resins are usually mixtures of organic compounds.This article focuses on naturally occurring resins.
