Can fluorosilicone extrusion be used in chemical - resistant applications?

Hey there! As a supplier of fluorosilicone extrusion, I often get asked if our products can be used in chemical-resistant applications. Today, I'm gonna dive deep into this topic to give you the lowdown.

First off, let's talk about what fluorosilicone extrusion is. Fluorosilicone rubber is a premium elastomer that combines the best of both worlds: the excellent heat resistance of silicone rubber and the outstanding chemical resistance of fluorocarbon rubber. When we extrude it, we shape it into various profiles that can be used in a wide range of industries.

One of the big questions is whether fluorosilicone extrusion can withstand different chemicals. Well, the short answer is yes, but it depends on the specific chemicals involved. Fluorosilicone has a pretty good resistance to a lot of aggressive chemicals, including some solvents, fuels, and oils.

For instance, in the automotive industry, where exposure to gasoline, motor oil, and hydraulic fluids is common, fluorosilicone extrusions can be a great choice. They can maintain their flexibility and sealing properties over time, even when in contact with these substances. This means less leakage and longer service life for automotive components.

In the aerospace industry, the requirements are even more stringent. Fluorosilicone extrusions are used in applications where they need to resist jet fuels, lubricants, and other aerospace chemicals. The ability to withstand these harsh chemicals is crucial for safety and performance.

But it's not all smooth sailing. There are some chemicals that can pose a challenge to fluorosilicone. Strong acids, like concentrated sulfuric acid or hydrochloric acid, can degrade fluorosilicone over time. Also, some highly polar solvents may cause swelling or loss of physical properties. So, before using fluorosilicone extrusion in a chemical-resistant application, it's important to test the specific chemical compatibility.

Now, let's take a look at the different types of fluororubber raw rubber that are used in the production of fluorosilicone extrusion. There are mainly two types: Peroxy Vulcanized Fluororubber Raw Rubber Peroxy Vulcanized Fluororubber Raw Rubber and Bisphenol Vulcanized Fluororubber Raw Rubber Bisphenol Vulcanized Fluororubber Raw Rubber.

Peroxy vulcanized fluororubber has better heat resistance and compression set properties. It's often used in applications where high temperatures and excellent sealing are required. On the other hand, bisphenol vulcanized fluororubber has good chemical resistance and is more cost - effective. Depending on the specific chemical environment and performance requirements, we can choose the right type of raw rubber to produce the fluorosilicone extrusion.

When it comes to the manufacturing process of fluorosilicone extrusion, we use advanced techniques to ensure the quality and performance of the products. Our extrusion process can produce profiles with precise dimensions and smooth surfaces. This is important because it affects how well the extrusion can seal against chemicals and other substances.

Moreover, we can customize the fluorosilicone extrusion according to your specific needs. Whether you need a special shape, size, or hardness, we can make it happen. This flexibility allows us to meet the diverse requirements of different industries and applications.

Another aspect to consider is the long - term performance of fluorosilicone extrusion in chemical - resistant applications. Over time, exposure to chemicals can cause some changes in the material. But with proper design and selection, we can minimize these effects. For example, we can add antioxidants or other additives to improve the chemical resistance and aging properties of the fluorosilicone.

In the food and beverage industry, there's also a demand for chemical - resistant materials. Fluorosilicone extrusion can be used in this sector as well, especially in applications where it needs to resist cleaning agents and disinfectants. And because it's a FDA - compliant material in many cases, it can be used in direct contact with food products.

In the pharmaceutical industry, where strict quality and chemical resistance standards are in place, fluorosilicone extrusion can also play an important role. It can be used in seals and gaskets for pharmaceutical equipment, ensuring that the equipment is protected from chemical corrosion and maintaining the integrity of the manufacturing process.

So, if you're looking for a reliable solution for chemical - resistant applications, fluorosilicone extrusion is definitely worth considering. But as always, it's important to do your research and make an informed decision. If you have any questions about whether our fluorosilicone extrusion is suitable for your specific application, don't hesitate to contact us. We're here to help you find the best solution for your needs.
