What are the storage conditions for fluororubber for gasket?

Hey there! As a supplier of Fluororubber for Gasket, I often get asked about the proper storage conditions for this amazing material. So, I thought I'd share some insights with you all in this blog post.

First off, let's talk about why proper storage is so important. Fluororubber is a high - performance elastomer known for its excellent resistance to heat, chemicals, and oils. But if it's not stored correctly, its properties can degrade over time, which can lead to issues when it's used in gaskets.

Temperature

One of the most critical factors in storing fluororubber is temperature. Fluororubber should be stored in a cool environment. Ideally, the temperature should be kept between 5°C and 25°C (41°F and 77°F). High temperatures can cause the rubber to harden and lose its elasticity. For example, if the storage area is too hot, say above 30°C (86°F), the fluororubber may start to break down at a molecular level. This can result in reduced sealing performance when it's made into a gasket.

On the other hand, extremely low temperatures can also be a problem. If the rubber is exposed to temperatures below 0°C (32°F), it can become brittle. When you try to use a brittle fluororubber gasket, it's more likely to crack during installation or operation, which defeats the purpose of having a reliable seal.

Humidity

Humidity is another aspect to consider. The storage area should have a relatively low humidity level, preferably between 30% and 60%. High humidity can lead to the growth of mold and mildew on the surface of the fluororubber. This not only looks bad but can also affect the rubber's chemical properties. Moisture can penetrate the rubber and cause swelling or hydrolysis, which can weaken the material.

For instance, if the humidity in the storage room is constantly above 70%, you might notice a change in the color and texture of the fluororubber over time. And once the rubber is compromised, it won't be able to provide the same level of performance as a properly stored one.

Light Exposure

Fluororubber should be stored away from direct sunlight and other sources of ultraviolet (UV) light. UV rays can cause the rubber to age prematurely. They break down the chemical bonds in the rubber, leading to discoloration, cracking, and a decrease in mechanical properties.

If you leave fluororubber in a place where it's exposed to sunlight for long periods, you'll start to see it turn yellowish or brownish. The surface may become rough, and small cracks may appear. To prevent this, store the rubber in opaque containers or in a dark storage area.

Chemical Exposure

Keep fluororubber away from chemicals that can react with it. Fluororubber is resistant to many chemicals, but there are still some substances that can damage it. For example, strong alkalis and some organic solvents can cause the rubber to swell or dissolve.

If you have a storage area where different chemicals are stored, make sure to separate the fluororubber from them. Even small amounts of chemical exposure can have a significant impact on the rubber's performance.

Packaging

Proper packaging is also crucial for storing fluororubber. It should be wrapped in a protective material, such as a plastic film or a special rubber - storage bag. This helps to keep out dust, moisture, and other contaminants.

The packaging should be sealed tightly to prevent air from getting in. Oxygen in the air can cause oxidation of the rubber, which can lead to hardening and degradation. So, a good seal is essential for maintaining the quality of the fluororubber during storage.

Types of Fluororubber and Their Storage

We offer different types of fluororubber for gaskets, and each may have slightly different storage requirements. For example, Food Grade Fluororubber is used in applications where it comes into contact with food. This type of fluororubber needs to be stored in an even more clean and controlled environment to ensure it remains safe for food - related use.

High Tear Resistance Fluororubber is designed to withstand high levels of stress. While it has good overall durability, proper storage is still necessary to maintain its tear - resistant properties.

Special Fluororubber for Watch Band has unique aesthetic and performance requirements. It should be stored carefully to prevent any damage that could affect its appearance or functionality.

Stacking and Handling

When storing fluororubber, be careful about how you stack it. Don't stack it too high, as excessive weight can cause deformation. If the rubber is deformed during storage, it may not fit properly when it's made into a gasket.

Also, handle the fluororubber with clean hands or appropriate tools. Dirt, oils, and other contaminants from your hands can transfer to the rubber and cause problems.

In conclusion, proper storage of fluororubber for gaskets is essential to maintain its quality and performance. By controlling the temperature, humidity, light exposure, chemical exposure, and using proper packaging, you can ensure that the fluororubber remains in top - notch condition until it's ready to be used.
