Synthetic Rubber vs. Viton
What's the Difference?
Synthetic rubber is a general term used to describe a wide range of man-made rubber materials, while Viton is a specific brand of synthetic rubber known for its exceptional resistance to heat, chemicals, and oil. While both materials are designed to mimic the properties of natural rubber, Viton is often preferred in applications where high temperatures and harsh chemicals are present due to its superior durability and performance. Additionally, Viton is more expensive than other types of synthetic rubber, but its unique properties make it a valuable choice for demanding industrial applications.

Further Detail
Introduction
Synthetic rubber and Viton are both popular materials used in various industries for their unique properties and applications. While synthetic rubber is a general term for a wide range of rubber-like materials, Viton is a specific brand of fluoroelastomer known for its exceptional chemical resistance. In this article, we will compare the attributes of synthetic rubber and Viton to help you understand their differences and determine which material is best suited for your specific needs.
Chemical Composition
Synthetic rubber is a man-made material that is derived from petroleum-based chemicals. It is typically a polymer composed of repeating units of monomers such as styrene, butadiene, or isoprene. On the other hand, Viton is a type of fluoroelastomer that contains fluorine atoms in its chemical structure. This gives Viton its unique properties, including excellent resistance to chemicals, oils, and extreme temperatures.
Physical Properties
When it comes to physical properties, synthetic rubber is known for its flexibility, elasticity, and durability. It can withstand a wide range of temperatures and is resistant to abrasion and tearing. Viton, on the other hand, is prized for its exceptional chemical resistance, particularly to acids, fuels, and solvents. It also has a high temperature range, making it suitable for applications where exposure to extreme heat is a concern.
Applications
Synthetic rubber is used in a wide range of industries, including automotive, construction, and manufacturing. It is commonly found in tires, hoses, seals, and gaskets due to its flexibility and durability. Viton, on the other hand, is often used in applications where resistance to harsh chemicals and high temperatures is required. This includes seals, O-rings, gaskets, and other components in chemical processing plants, oil refineries, and aerospace industries.
Cost
One of the factors to consider when choosing between synthetic rubber and Viton is the cost. Synthetic rubber is generally more affordable than Viton, making it a popular choice for applications where cost is a primary concern. However, Viton's superior chemical resistance and temperature range may justify the higher cost for certain applications where performance is critical.
Environmental Impact
Both synthetic rubber and Viton have environmental implications due to their petroleum-based origins. Synthetic rubber production can result in the release of greenhouse gases and other pollutants, contributing to environmental degradation. Viton, on the other hand, contains fluorine compounds that are known to be persistent in the environment and can have toxic effects on wildlife. It is important to consider the environmental impact of both materials when choosing between synthetic rubber and Viton for your applications.
Maintenance and Durability
When it comes to maintenance and durability, synthetic rubber is known for its long-lasting properties and resistance to wear and tear. It requires minimal maintenance and can withstand exposure to various environmental conditions. Viton, on the other hand, is highly durable and resistant to chemicals, but it may require more specialized maintenance to ensure optimal performance over time. Regular inspection and testing may be necessary to prevent degradation and ensure the longevity of Viton components.
Conclusion
In conclusion, synthetic rubber and Viton are both valuable materials with unique properties and applications. Synthetic rubber is a versatile and cost-effective option for a wide range of industries, while Viton offers superior chemical resistance and temperature range for demanding applications. When choosing between synthetic rubber and Viton, consider factors such as chemical compatibility, temperature requirements, cost, and environmental impact to determine the best material for your specific needs.
