Coumarone-Indene Resin
Product Code: CIRESIN130
Coumar resin also known as Coumarone-Indene Resin is a thermoplastic low molecular weight, hydrocarbon resin produced by catalytic polymerization of predominantly indene and other aromatic monomers.
While coumar resins can be liquid or solid, this grade is in the form of solid flakes with softening point of about 130șC.
Coumar resin is soluble in organic solvents such as chlorinated hydrocarbons, esters, ketones, ethers, hydrocarbons, most resin oils, nitrobenzene, anilines, etc., but insoluble in water and lower alcohols. Excellent acid and alkali resistance and water resistance. Good electrical insulation, aging resistance, and heat resistance. Shows a neutral reaction. It has thermoplasticity and corrosion resistance. The light fastness is poor, Combustible, Non-toxic.
Coumarone resin is widely used in rubber, tires, triangle belts, conveyor belts, paint, ink, waterproof, hose and other industries.

Additional Description
Coumarone resin is widely used in rubber, tires, triangle belts, conveyor belts, paint, ink, waterproof, hose and other industries. No matter it is coumarone resin, liquid coumarone or rubber alone, it has no adhesion, and it is compounded. Later, it can make the rubber have good adhesion, including pressure sensitivity or hot melt. In the past, the adhesive was mostly used for natural rosin resin or indenene resin. The price is high, the source is unstable, and the performance is not as good as coumarone resin. At the same time, the price of coumarone resin is lower than that of rosin, and the output of coumarone resin is more stable than that of rosin. Coumarone resin has occupied a dominant position in adhesives in industries such as rubber. Coumarone resin added to rubber can play a role in softening, strengthening, thickening, dispersing, etc., thereby improving the processing performance of the rubber.
