Coumarone resin factory

The chemical composition of Coumarone resin is quite unique, mainly prepared by catalytic copolymerization of two monomers, benzofuran (also known as oxyindene) and indene. Below, Coumarone resin factory will explain in detail:
Benzofuran (oxyindene): This is a compound with a special chemical structure, containing aromatic heterocycles, which provides important chemical properties for ancient Malone resin.
Indene: This is a polycyclic aromatic hydrocarbon with two fused ring structures, and is an indispensable part of the chemical composition of Coumarone resin.
The preparation of Coumarone resin usually involves extracting benzofuran and indene or their homologues and derivatives from specific fractions of coal tar (such as 160-185 ℃ fractions), processing and refining them, and then conducting catalytic copolymerization reactions to obtain this polymer material. Due to the presence of aromatic heterocyclic structures in the molecules of Coumarone resin, it has good solubility, miscibility, water resistance, acid and alkali resistance, and excellent electrical properties.
In addition, the appearance of Coumarone resin varies with the degree of polymerization, and can be a transparent to black viscous liquid or solid. Its physical properties such as relative density and softening point may also vary depending on the degree of polymerization. These characteristics make Coumarone resin widely used in various fields such as rubber, paint, ink, waterproof materials, etc.
