Heat- and ozone-resistant suction cups

Made from a hydrogenated nitrile rubber (HNBR yellow) material, a series of 10 new bellows suction cups have been introduced to the market. These cups from FIPA (Atlanta, GA) are available in 1.5- and 2.5-fold models, in 11- to 60-mm diameters. The HNBR cups are said to be ideal for moving hot plastic parts from molds without markings typically left on the product by temperature-resistant silicon vacuum cups. Nitrile butadiene rubber (NBR) cups are resistant to oils and chemicals, but have been limited in that ozone and heat degrade the properties. FIPA has found a way to selectively hydrogenate the double bond in NBR but not the entire nitrile group, which allows the material to withstand a greater amount of heat. The cups are compatible with FIPA’s modular systems.
