VitonÂ® Sponge plays a particularly vital role in cases where soft flouroelastomers are desirable. hardness limit for solid VitonÂ® is 55 durometer. the heat and fluid resistance of solid VitonÂ® is necessary. high resistance to ozone attack, and low moisture absorption. 24â x 48â in 1/8â, 1/4â and 3/8â thicknesses.
0. Buna-N is a common trade name for nitrile rubber, while Viton is a trade name for Fluorocarbon rubber. Viton has better chemical and temperature resistance than Buna, but Buna is usually less expensive. The exception is applications involving ammonia gas, where Buna has superior resistance to attack.Our advice is to choose the Viton for most applications.iton has better chemical and temperature resistance than Buna, but Buna is usually less expensive.
