Coumarone Resin SR90Y Enhances Processing Performance with 96.0～116.0 Softening Point for Improved Self-adhesion in Rubber Products
Product Details
Improves Self-adhesion Coumarone Resin
,Enhances Processing Performance Aromatic Resin
,96.0～116.0 Softening Point Rubber Tackifying Resin
- 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
- 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)
