The marine, automotive, and construction industries all use rubber molding. A fluoropolymer elastomer is added to Viton™ rubber, a specialty synthetic rubber. Viton™ rubber is particularly resilient in applications subjected to potent chemicals because of this combination. In addition, Viton™ performs well even in extreme weather or high temperatures, which makes it ideal for molding applications when the circumstances aren’t optimal. Although Viton™ rubber is more expensive than most rubber parts, it is also more robust and will probably last much longer than any other type of rubber grade used for molding. Read More…

Processes for Molding Viton™ Rubber
Viton™ rubber can be produced using either compression molding or injection molding. In the molding technique known as compression molding, a charge is squeezed to conform to the shape of a mold that has a bottom and upper half. Multiple components that operate as a single mechanism when compression is applied may make up a part. A cavity that defines the required shape is left between the mold's two parts when they come together. Parts are joined at the shape's broadest cross-section to make it easier for the product to be ejected after curing. For thermosetting materials, it is the most affordable molding technique.
Flash molds are the most popular compression molds, including positive, landing positive, and semi-positive molds. Bulk and sheet compression molding are the two forms, and fillers, catalysts, stabilizers, colors, and fiber reinforcers are typically used in bulk molding. In any case, the advantages of compression molding thermoset polymers include exceptionally high strength, lightweight products featuring corrosion resistance. An uncured rubber form roughly resembles the product's shape and is placed into an accurate mold during the compression molding process, where it is squeezed between the plates. This pressure squeezes out the extra rubber and air, and the rubber is then heated to aid in curing.
The heated rubber is forced through a machine barrel and out of a nozzle during the injection molding, after which it is injected into a mold. It forms the appropriate rubber part when it cools by filling the mold's voids. Before the rubber is taken out of the mold and used for packing, it is given time to cure.
Viton™ Rubber Characteristics
Viton™ is distinguished from other non-fluorinated elastomers by its:
- Resistance to degradation by a wider range of fluids and chemicals.
- Excellent resistance to lubricants, oils, fuels, and most mineral acids.
- Extremely low permeability to various substances, with an especially strong performance in gasoline with added oxygen.
- Resistance to solvents that dissolve other rubbers, such as aliphatic, aromatic hydrocarbons.
- Extremely strong compression set resistance, even at high temperatures.
- Exceptionally strong resistance to weather, sunlight, and atmospheric oxidation.
- Good electrical properties in low voltage, low-frequency applications; it provides excellent resistance to fungi and mold.
- Low flammability: it is naturally more flammable-resistant than other, non-fluorinated hydrocarbon rubbers.
Viton™ Rubber Molding in Engines
The O-rings of a car's fuel injectors frequently have Viton™ rubber molding. Gasoline compression is maintained thanks to the material's flawless seal, and despite being continuously exposed to fuel while the engine is operating, Viton™ rubber does not degrade. Because engines generate a lot of heat while operating, Viton™ rubber is ideal for withstanding the conditions beneath a car's hood. The same idea holds for engines found in both boats and construction machinery. Using Viton™ rubber molding reduces deterioration that could result in leaks or engine problems because boats are particularly susceptible to rubber disintegration if used in saltwater.
Advantages of Viton™ Molding Rubber
Viton™ molding rubber is better able to endure high temperatures while preserving excellent mechanical qualities than most elastomers. The resistance to oil and chemicals is unaffected by high temperatures. When subjected to intermittent exposures up to 316°C or laboratory air oven aging up to 204°C, Viton™ compound materials maintain a significant amount of their elasticity. More than any other non-fluorinated elastomer, Viton™ grades also withstand deterioration from a greater range of chemicals and fluids, including oils, fuels, lubricants, and most mineral acids. It offers the best fluid resistance of any commercial rubber, to put it simply. Viton™ is recognized to function remarkably well in oxygenated automobile fuels because of its low permeability to various chemicals. Viton™ has more robust qualities than that, though. Since they exhibit strong compression resistance even at temperatures that would lead other non-fluorinated elastomers to become brittle, it has a high level of resistance to fungus, mold, sunlight, climate change, and air oxidation.
Choosing the Proper Viton™ Rubber Molding Company
To make sure you have the most productive outcome when selecting a Viton™ rubber molding company, it is important to compare at least 5 companies using our Viton™ rubber molding directory.
