Nuremberg, Germany – During DKT 2018 in Nuremberg, Germany, Arlanxeo presented a new fully hydrogenated nitrile rubber (HNBR) including a termonomer, which it said had never been used before with these rubbers.
Terpolymer Therban ST 3107 VP offers a “unique solution” for complex applications requiring both good low-temperature flexibility and excellent oil resistance, said Susanna Lieber, global head of technical marketing for Therban.
Arlanxeo has filed a patent application for the new polymer, which was developed at the company’s sites in Dormagen, Germany and La Wantzenau, France.
“Our new Therban product can reduce the glass transition temperature by up to 10°C in rubber compounds, while maintaining excellent media resistance,” added Lieber.
The elastomer is further claimed to offer “good resistance to high temperatures and in contact with fuels, oil and gas, as well as excellent mechanical properties.”
Target markets, said Arlanxeo, include the automotive industry for the production of timing belts and the oil extraction industry in stator/rotor systems for drilling.
