Braskem Unilene® BS-130 Thermoplastic Hydrocarbon Resin C9
Categories:	Polymer; Thermoplastic
Material Notes:	Thermoplastic hydrocarbon resin C9 is obtained from catalytic polymerization of hydrocarbons in a continuous process. Compatible with most solvents and polymeric materials, it has hydrophobic characteristics and has a format of light yellow pellets. In rubbers, Unilene improves processability, filler incorporation, dispersion and mass adhesion, avoiding elastomer degradation and reducing preparation time. In Solvent and Hot Melt adhesives, the resin promotes good adhesion, cohesion, excellent open time and water repellency. Applications: Hot melt adhesives (EVA, metallocene PE and PSA) and solvent based , In addition, the product can be used for seals and sealants, paints and varnishes (road marking, printing inks, aluminum and protective, epoxy and alkyd systems), tires and rubber artifacts and polymer modification.
