Low viscosity line.


Therban AT C 3443 VP and Therban AT A 3904 VP have been added to the Therban AT line. Therban AT grades are said to exhibit significantly lower viscosity values than standard HNBR HNBR Hydrogenated Acrylonitrile-Butadiene Rubber  products. Users are said to benefit from easier, faster mixing, higher filler tolerance for the mixture, shorter cycle times in injection molding injection molding
n.
A manufacturing process for forming objects, as of plastic or metal, by heating the molding material to a fluid state and injecting it into a mold.
 and enhanced surface quality for extrudates. Therban AT is therefore said to be suitable for producing complex shapes, including fine seals for the automotive and industrial sectors, parts with long flow paths, such as stators for eccentric screw pumps or blowout preventers A blowout preventer (BOP) is a large valve that encases an oil well at surface. During drilling or well interventions, the valve may be closed if overpressure from an oil reservoir causes formation fluids such as oil and natural gas to back up within the wellbore and  for the oil industry, calendered cal·en·der  
n.
A machine in which paper or cloth is made smooth and glossy by being pressed through rollers.

tr.v. cal·en·dered, cal·en·der·ing, cal·en·ders
 mixtures for belts, extrudates including profiles, hoses and cables, and extremely hard rollers.
