Product Description
Detailed Specifications And Features
Coumarone-indene Resins and Aromatic Resins improve the self-adhesion and inter-adhesion of rubber compounds, and are used in various rubber products such as tires and conveyor belts.
Product Overview
Coumarone Resin SR90Y
Product Characteristics
Coumarone resin SR90Y is primarily a mixture of aromatic resins and coumarone-indene resins. Manufactured from carefully selected high-quality petroleum cracking fractions, this product offers excellent compatibility with various rubbers and fillers, significantly enhancing the tackiness and adhesion of rubber compounds.
Key Benefits
  • Improves processing performance while maintaining moderate viscosity and softness
  • Prevents rapid hardening and caking, reducing mixing operation difficulties
  • Accelerates uniform dispersion of materials by quickly wetting inorganic fillers
  • Enhances calendering and extrusion performance while reducing wear
  • Flammable but non-toxic with no impact on vulcanization characteristics
  • Provides excellent scorch safety and improves physical properties of vulcanized rubber
Application Areas
Ideal for tires, conveyor belts, and various rubber products.
Not suitable for white or transparent rubber products.
Usage Instructions
  • Granular form suitable for automatic metering and manual mixing
  • Add at the beginning of mixing process for optimal dispersion
  • Recommended for internal mixers with temperature at least 10°C above softening point
  • General dosage: 0.5-10.0 phr (conduct small-scale tests before use)
