LITHENE™ ULTRA N4-9000 is a viscous, narrow molecular weight liquid polybutadiene with a low content of 1,2 vinyl microstructure. It is characterized by extremely low odor and volatiles and is primarily used as a polyurethane additive to enhance abrasion resistance. Typical applications include automotive sound damping sealants and adhesives, as well as dry sand binders.

LITHENE™ ULTRA AL is a viscous, low molecular weight liquid polybutadiene with a high content of 1,2 vinyl and cyclic vinyl microstructures. It has a low odor and is used as a binder in automotive sealants and UV-cured flexographic printing plates. Typical applications include automotive sound damping sealants, semi-structural adhesives, antifoaming coating additives, and as a plasticizer for flexographic printing plates.

​LITHENE™ ULTRA N4-5000 is a medium viscosity, narrow molecular weight liquid polybutadiene characterized by its low 1,2 vinyl microstructure content. With extremely low odor and volatile levels, it is suitable for use as a component in polyurethane foam mold release formulations and as a base for further chemical modifications like maleinisation. Typical applications include serving as a polyurethane foam mold release additive, a dry sand binder, and a base polymer for maleinisation.

LITHENE™ ULTRA AL-15MA is a highly viscous, low molecular weight liquid polybutadiene, produced from the low-odor base Lithene Ultra AL and adducted with 15 parts maleic anhydride. It serves as a highly efficient adhesion promoter, particularly in sulfur-cured automotive sealants. Typical applications include use as an adhesion promoter in automotive sealants and semi-structural adhesives, rubber-to-metal adhesion, and electrical encapsulants.
