Coumarone resin is a viscous liquid or solids, the relative density of 1.05 to 1.15; 1.05 to 1.07 relative density of liquid. It looks like rosin, dissolved in chlorinated hydrocarbons, esters, ketones, ethers, hydrocarbons, most oleoresins, nitrobenzene, aniline and other organic solvents, insoluble in water and lower alcohols. Acid, water resistance. Electrical insulation, resistance to aging, good heat resistance. Neutral reaction. Thermoplastic, corrosion resistance. Poor lightfastness. Combustible.
Property:
Coumarone resin, ethylene tar, carbon nine as the raw material obtained by catalytic polymerization reaction, the product appearance is yellow, brown, black bulk solids with good compatibility, water resistance, acid and alkali resistance, rust and electrical characteristics .
Applications:
Coumarone resins are widely used in rubber, tires, V-belts, conveyor belts, paint, ink, water, hoses and other industries, whether it is coumarone resins, coumarone or liquid rubber alone are no bonding, complex after the rubber can have good adhesion, including pressure-sensitive or hot melt, adhesive used for the past natural rosin resins or indene resins, high prices, sources of instability, performance is not as coumarone resin, Meanwhile coumarone resin lower in price than the rosin, and rosin coumarone resin production yield stability than is currently in the rubber industry coumarone resin binder has been dominant. Coumarone resin added to rubber, it can play a softening, reinforcing, thickening and dispersion effect, thus improving the processing properties of rubber.
