A, B, F, and ETP are the four main families of VitonTM fluoroelastomers, and each has distinct performance traits of its own. piston seals for hydraulic cylinders
DuPont markets a synthetic rubber and fluoropolymer elastomer under the Viton® trademark, which is frequently utilized in O-rings and other molded or extruded goods.viton oil seal
Disadvantages. Even though Viton is one of the greatest elastomers, it is not without drawbacks. Although it has a reputation for being fluid-resistant, it is not resistant to organic acids, ketones, or esters. Although vitron can tolerate high temperatures, it is nevertheless impacted by both extremes of the temperature range.
calcium hydroxide in solid formSince CO2 is an acidic oxide, an alkali may absorb it more efficiently. Thus, the most effective substance for collecting carbon dioxide is cold, solid calcium hydroxide. oil seal manufacturing
The same family of synthetic rubber materials is known by several names, including Viton®, FKM, FPM, and fluoroelastomer.
The Chemours Company is the registered trademark holder of Viton®, a particular brand of fluorocarbon (FKM). The o-rings for automobile gasoline handling systems, aircraft engines, and other applications needing high temperatures and low compression set frequently use this synthetic rubber polymer.
In terms of resistance to heat and chemicals, Viton excels. It has a strong mechanical foundation as well. However, due to its higher potential cost, it is not as flexible as silicone, particularly at lower temperatures.
Viton rubber seals are easily identified by their reddish-brown color, however certain manufacturers may offer them in grey as well. They also feature a stainless-steel garter spring.
There are several advantages to using nitrile o-rings, gaskets, and other sealing materials. Resistance to hydraulic fluids, silicone greases, alcohols, water, and petroleum-based oils and fuels are a few of its best qualities.
Viton ® O-rings come in brown or black hue and are easily obtainable off the shelf. Because Viton ® O-rings are heat resistant, they are ideal for applications requiring excellent chemical resistance and temperatures above +400°F. FKM provides exceptional resistance to ozone, weathering, and sunshine.
