[ClickPress, Wed Jul 24 2019] Hydrogenated nitrile butadiene rubber (HNBR) has been prevalently known for retention of properties and physical strength post long-term exposure to oil, heat and chemicals.
Products such as o-rings, seals, synchronous timing belts, suspension parts, mountings, hoses and fan belts all necessitate frequent replacement, benefiting the global HNBR market.
Grippers in the new '100' series are equipped with temperature-resistant HNBR pads or fully coated gripper jaws to avoid scratching or damaging applications such as chromed or painted plastic parts, or those with restricted space.

Lanxess says the HNBR market is currently growing globally at a double-digit annual rate, due in particular to a strong global demand from automotive manufacturers, especially in China and India.
AO-80 was directly mixed with HNBR on an open two-roll mill under room temperature with the AO-80 content of 5, 10, 30, 50, 80, and 100 phr (parts per hundred resin), respectively.
For example, thermoplastic molders are just discovering the potential of a new type of hydrogenated nitrile butadiene rubber (HNBR) commercialized by Lanxess in 2005.
The composite is based on the "optimal integration" of special grades of Durethan polyamide, serving as the hard engineering thermoplastic, and a variant of Therban hydrogenated nitrile butadiene rubber (HNBR) as the elastomer component.
HNBR is a widely used elastomer for which properties can be tailored through variation of the degree of nitrile and olefinic groups along the polymer chain.
The EPDM sealing element is used in any type of water system and for low-pressure steam; the HNBR sealing element is designed for fuel oil and gas systems; and the FKM sealing element is used for applications where increased chemical resistance is required, as well as for low-pressure steam.
