Hey there! As a supplier of Strip Seal for Containers, I often get asked about what these seals are made of. So, I thought I'd write this blog to break down the chemical composition of strip seals for containers.
First off, let's talk about why the chemical composition matters. Strip seals play a crucial role in containers. They're responsible for keeping out moisture, dust, and other contaminants, and they also help with insulation. The right chemical makeup ensures that the seals are durable, flexible, and can withstand different environmental conditions.
One of the most common materials used in strip seals for containers is EPDM, which stands for Ethylene Propylene Diene Monomer. EPDM is a synthetic rubber that's known for its excellent weather resistance. It can handle extreme temperatures, from really cold to quite hot, without losing its properties. This is super important for containers that are shipped all over the world and might be exposed to different climates.
The chemical structure of EPDM consists of ethylene, propylene, and a small amount of a diene monomer. The ethylene gives the rubber its strength and flexibility, while the propylene helps with its resistance to heat and chemicals. The diene monomer is what allows the rubber to be cross - linked during the vulcanization process. Vulcanization is like a magic process that turns the soft, sticky rubber into a tough, durable material. It makes the rubber less likely to stretch out of shape and more resistant to wear and tear.
Another benefit of EPDM is its resistance to ozone. Ozone is a gas in the atmosphere that can cause rubber to crack and degrade over time. But EPDM can stand up to ozone pretty well, which means the strip seals will last longer. This is especially important for containers that are stored outdoors for long periods.
Some strip seals might also contain additives. These additives can enhance certain properties of the seal. For example, there are antioxidants that help prevent the rubber from oxidizing. Oxidation can make the rubber hard and brittle, so antioxidants keep the seal flexible and in good condition. There are also UV stabilizers. These protect the seal from the harmful effects of the sun's ultraviolet rays. Just like we use sunscreen to protect our skin from the sun, UV stabilizers protect the rubber from getting damaged by UV light.
Now, let's talk about the physical properties that the chemical composition gives to the strip seals. Thanks to the EPDM and its additives, the strip seals are very flexible. This flexibility allows them to fit snugly around the edges of the container doors and other openings. They can be easily bent and shaped during installation, and they'll still maintain their sealing performance.
The seals also have good compression set resistance. Compression set is what happens when a rubber seal is compressed for a long time and doesn't bounce back to its original shape. A good strip seal should have low compression set, which means it will continue to provide a tight seal even after being compressed for a long time. This is important because the seals are constantly being compressed when the container doors are closed.
