Braskem America A-90 LN is a low molecular weight, thermoplastic aromatic C9 hydrocarbon resin obtained through catalytic polymerization in a continuous process, pastillated in a pearl-like shape, and presented in a yellow colored scale. Compatible with most solvents and polymeric materials. Unilene A-90 LN has a controlled naphthalene content, which allows for a less pronounced odor when compared to regular C9 hydrocarbon resins. In Rubbers, Unilene improves the processability of compounds, filler incorporation, dispersion, and tack of the mixture, avoiding elastomer deterioration and reducing the preparation time. For applications in Hot Melt and solvent-based Adhesives, the resin promotes tack, wetting, cohesion, open time control, and water repellency.
