Anaheim, California -- Simrit debuted its expanded line of nitrile butadiene rubber (NBR) sealing materials during the Windpower 2011 show in Anaheim, California from May 22 to 25, the company said in a 23 May announcement.
Simrit's two new NBR developments are part of its Ventoguard line of materials, which it says are specifically designed to offer excellent grease and ozone resistance, low compression set and low-temperature capability.
"The windpower industry is growing and evolving at a rapid pace," said Reddy Tudi, sales director, renewable energy, Simrit. "To meet the unique needs of this developing industry, Simrit engineers are continually driving the development of materials and seals that will extend the performance of windpower applications."
Ventoguard 453 and Ventoguard 454 are the new additions to Simrit's well-established line of proven NBR materials. Primarily used in slewing bearing profile seals in wind turbines, both materials were developed for long-term reliability and superior resistance to environmental and chemical concerns.
Additionally, each material was designed to address a specific windpower-related challenge with the ultimate goal of helping prolong the maintenance cycle of the sealing application.
Ventoguard 453 is designed to offer excellent cold flexibility, very good compression set and Simrit said it demonstrates superior aging in several greases, including Kluber, Fuchs and Mobil. Ventoguard 454 provides superior compression set and is optimised for use in Shell Rhodina BBZ greases, Simrit said.
Simrit is part of the group Freudenberg-NOK Sealing Technologies, which has total annual sales of more than $7 billion.
