Versatile liquid polybutadienes with a wide range of industrial applications
- Hydrophobicity
- Flexibility
- Electrical resistance
- Chemical resistance
- Oil and solvent compatibility
- Adehesion
Synthomer’s LITHENE™ liquid polybutadiene products impart many valuable properties when incorporated into end formulations, and contribute to exceptional performance in a wide range of applications.
Their excellent compatibility with hydrocarbon solvents and reactivity with many vulcanised rubbers makes them extremely versatile in a variety of ambient, UV and heat-curable applications. Maleic anhydride grafting increases polarity to enhance adhesion direct to metals and additionally allows the liquid polybutadienes to react with amines and polyols.
LITHENETM products are 100% active liquid polybutadienes, available in a range of molecular weights and micro-structures. They are unsaturated and reactive viscous liquids, with excellent low-temperature flexibility, high electrical resistance and are very hydrophobic.
