Is 85% formic acid flammable?

Jun 10, 2025

Hey there! As a supplier of 85% formic acid, I often get asked, "Is 85% formic acid flammable?" It's a valid question, especially when dealing with chemicals. So, let's dive right into it and clear up any confusion.

First off, what exactly is formic acid? Well, formic acid (HCOOH) is a colorless, pungent - smelling liquid. It's found naturally in things like ants and stinging nettles. Commercially, it's used in a whole bunch of industries. You'll find it in leather tanning, textile processing, and even as a preservative in animal feed.

Now, back to the big question: is 85% formic acid flammable? The short answer is yes, 85% formic acid is flammable. Formic acid has a relatively low flash point. The flash point is the lowest temperature at which a liquid gives off enough vapor to form an ignitable mixture with air near the surface of the liquid. For 85% formic acid, the flash point is around 69°C (156°F). This means that if it's exposed to an ignition source at or above this temperature, it can catch fire.

But it's not just about the flash point. There are other factors that come into play when it comes to the flammability of 85% formic acid. The concentration matters a lot. A higher concentration of formic acid means there are more formic acid molecules per unit volume. This results in more vapor being produced at a given temperature, increasing the likelihood of an ignitable mixture forming. So, that 85% concentration is significant.

When handling 85% formic acid, you've got to be really careful. It's not just the fire risk; formic acid is also a strong irritant. It can cause burns to the skin, eyes, and respiratory tract. So, proper safety gear is a must. You should wear gloves, goggles, and a respirator if you're working in an area with a high concentration of formic acid vapors.

Let's talk about storage. If you're storing 85% formic acid, you need to keep it in a cool, well - ventilated place. It should be away from heat sources, open flames, and oxidizing agents. Oxidizing agents can react with formic acid and increase the risk of fire. And make sure the storage containers are made of materials that are resistant to formic acid. Stainless steel or certain types of plastics work well.

Now, I know some of you might be wondering about the applications of 85% formic acid in different industries. In the leather industry, it's used for deliming and bating processes. It helps to remove lime from the leather and makes it softer and more pliable. In textile processing, formic acid is used as a dyeing and finishing agent. It helps the dyes to bind better to the fabric, resulting in more vibrant and long - lasting colors.

But formic acid isn't the only chemical we deal with. We also supply other chemicals like Neopentyl Glycol(NPG), Bisphenol A (also known as BPA). Neopentyl Glycol is used in the production of coatings, resins, and plasticizers. Bisphenol A is used in the manufacturing of polycarbonate plastics and epoxy resins.

If you're in an industry that uses 85% formic acid or any of these other chemicals, you need a reliable supplier. That's where we come in. We've been in the business for a while, and we know how to handle and supply these chemicals safely and efficiently. Our 85% formic acid is of high quality, and we can deliver it to you in the right quantity at the right time.

When it comes to transporting 85% formic acid, there are strict regulations. It's classified as a hazardous material, so it has to be transported in approved containers and vehicles. The drivers need to be trained in handling hazardous materials. We make sure all these regulations are followed to ensure the safe delivery of our products.

In case of a fire involving 85% formic acid, you can't just use any fire extinguisher. Water - based extinguishers might not be the best choice because formic acid is soluble in water, and it could spread the fire. Instead, dry chemical or carbon dioxide extinguishers are recommended. These types of extinguishers can smother the fire and stop the combustion process.

Another thing to consider is the reactivity of 85% formic acid. It can react with certain metals like iron and aluminum. When it reacts with these metals, it can produce hydrogen gas. Hydrogen is highly flammable, so this adds another layer of risk. That's why it's important to avoid contact with these metals when handling formic acid.

If you're new to using 85% formic acid, it's a good idea to get some training. There are courses available that teach you about the proper handling, storage, and safety procedures for formic acid. This can help you prevent accidents and ensure the well - being of your employees.
