As a supplier of plastic fasteners for cars, I often get asked a bunch of questions from my customers. One question that pops up quite a bit is, "Are plastic fasteners for cars resistant to chemicals?" Well, let’s dig into this topic and see what’s what. Plastic Fasteners for Cars
First off, it’s important to understand the environment plastic fasteners in cars are exposed to. Cars are like little chemical reactors on wheels. They’ve got all kinds of fluids sloshing around, from engine oil to coolant, brake fluid, and windshield washer fluid. All these chemicals have different properties and can potentially affect the plastic fasteners.
Now, not all plastics are created equal. There are several types of plastics used in making car fasteners, and each has its own level of chemical resistance.
One of the most commonly used plastics is nylon. Nylon is a tough and durable material, and it generally has a pretty good resistance to many automotive chemicals. It can handle a fair amount of diesel, gasoline, and engine oil without getting too messed up. For example, in the engine compartment, where fasteners are constantly in contact with these fuels and lubricants, nylon fasteners can hold up okay for a long time. However, it’s not invincible. Some strong solvents and certain types of brake fluids can cause nylon to swell or degrade over time. If you expose nylon fasteners to a brake fluid with a high glycol content for an extended period, you might start to notice a change in their physical properties, like a loss of strength or a change in shape.
Another popular plastic is polypropylene. Polypropylene is known for its excellent chemical resistance to a wide range of substances. It can resist most automotive fluids, including acids, alkalis, and some solvents. This makes it a great choice for fasteners in areas where they might come into contact with corrosive chemicals. For instance, in the undercarriage, where the fasteners are exposed to road salts (which can be quite corrosive) during the winter months, polypropylene fasteners can maintain their integrity better than some other plastics.
Then there’s POM (polyoxymethylene), also known as acetal. POM is a super-strong plastic with high stiffness and dimensional stability. It has good resistance to many common automotive chemicals, like water, oil, and gasoline. But, it’s not very resistant to strong acids or bases. If you use POM fasteners in an area where they’re likely to be exposed to a strong chemical spill, you might run into trouble.
So, how do we test the chemical resistance of these plastic fasteners? Well, in our lab, we’ve got a bunch of tests we run. One of the most basic ones is the immersion test. We take samples of the plastic fasteners and soak them in different chemicals for a set period. Then we measure things like weight change, dimensional change, and mechanical strength before and after the immersion. If the fastener doesn’t show much change in these properties, we can say it has good chemical resistance to that particular chemical.
We also do stress cracking tests. Sometimes, even if a plastic is resistant to a chemical on its own, the combination of the chemical and stress can cause cracks to form. In these tests, we apply a certain amount of stress to the fasteners while they’re in contact with the chemical. If they don’t crack or break, that’s a good sign.
But, it’s not just about what happens in the lab. Real-world conditions can be a lot more unpredictable. For example, temperature can have a big impact on how plastics react to chemicals. Higher temperatures can speed up chemical reactions and make the plastics more vulnerable. So, a fastener that might be okay at room temperature could start to break down if it’s in an engine compartment where the temperature can get really hot.
Also, the duration of exposure matters. A short burst of contact with a chemical might not do much damage, but continuous exposure over months or years can wear down even the most resistant plastics.
So, what does this all mean for you, the customer? Well, if you’re in the automotive industry and you’re looking for plastic fasteners, it’s crucial to think about the chemical environment they’ll be in. If the fasteners are going to be in an area with lots of fuel and oil, nylon or polypropylene might be good choices. But if they’re likely to be exposed to strong acids or bases, you’ll need to look for something more resistant.
