Braskem America B-120 LN

Braskem America B-120 LN is a hydrocarbon resin obtained through catalytic polymerization in a continuous process. It comes in light yellow pellet form and exhibits hydrophobic characteristics. Compatible with various solvents and polymeric materials, Unilene® B-120 LN has a controlled naphthalene content, resulting in a less noticeable odor compared to regular C9 hydrocarbon resins. In rubber applications, it enhances processability, filler incorporation, dispersion, and adhesion, while preventing elastomer degradation and reducing preparation time. For solvent and hot melt adhesives, the resin provides excellent adhesion, cohesion, extended open time, and water repellency.

Packaging & Availability

Packaging Type: Bags
Packaging Information: The resins are supplied in 25 ± 0.2 kg polyethylene bags and are supplied in pellet format.

Storage & Handling

Shelf Life: 2 years
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.
