LITHENE™ ULTRA N4-5000-10MA is a viscous, low molecular weight liquid polybutadiene, adducted with 10 parts maleic anhydride. It is characterized by very low odor and volatiles, making it suitable for specialized applications such as soft, isocyanate-free electrical encapsulants and rubber-to-metal bonding.

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.
