ADIPRENE Adiprene LF Low free prepolymers LF Urethane Prepolymers minimize exposure to free isocyanate, a subject of increasing regulatory focus. LANXESS is the only manufacturer offering LF urethane prepolymers with levels of free isocyanate below 0.1%wt across a wide range of chemistries, including TDI, MDI, pPDI, IPDI, and HDI. Adiprene® LF prepolymers have low res.


  • Adiprene® and Vibrathane® MDI and TDI prepolymers can be used with Vibracure® curatives to produce elastomers for a range of demanding applications requiring outstanding toughness, abrasion resistance, load-bearing capacity, cut resistance, and resistance to heat build-up. In mining, urethane systems yield components with abrasion resistance and weight reduction compared to traditional materials like steel and other elastomers. For tires and wheels, urethane carries higher loads at higher speeds with lower rolling resistance than other elastomers. In belting, urethane delivers longer lifetime due to outstanding toughness.
