Braskem America A-90 is a thermoplastic hydrocarbon resin C9 obtained through catalytic polymerization of hydrocarbons in a continuous process. These light yellow pellets possess hydrophobic characteristics and are compatible with various solvents and polymeric materials. In rubbers, A-90, also known as Unilene, enhances processability, filler incorporation, dispersion, and mass adhesion, preventing elastomer degradation and reducing preparation time. Additionally, in Solvent and Hot Melt adhesives, the resin promotes good adhesion, cohesion, excellent open time, and water repellency.
