Braskem America A-90 LN

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.

Recommended Storage & Handling Conditions

Hydrocarbon resins have thermoplastic characteristics, they can agglomerate when subjected to high temperatures and/or under pressure (stacking). It is recommended to store the product in a fresh place, free from direct sunlight, moisture and without stacking the pallets, also avoiding direct contact with the soil. This characteristic is considered more crucial for low softening point resins such as Unilene A‐80, A‐90, and A‐90 LN.
