大自然给了我们一个best gasket materials possible —rubber. Natural rubber can stretch and has the same elasticity in all directions, something wholly unique to the material.
But the problem with natural rubber is that it can degrade over time — just like anything from nature — and while it does offer certain resistances, it can be vulnerable to oils and chemicals. That means it doesn’t always make the best choice forgasketing material. That’s whereneoprenesteps in.
Neoprene is a hugely popular and widely used material for gasketing material. You’re probably experiencing it in your house or workplace at this very instant.Neoprene gasket chemical resistancein particular is quite impressive, which is one of its biggest draws.
Let’s dive into what you need to know about neoprenebefore choosingyour gasketing material.
What is Neoprene?
Neoprene was the answer to the need for rubber products when natural rubber was in extreme demand in1930. It’s asynthetic substitute for rubberthat was developed to fill many of the same roles that rubber had up to that point.
Neoprene is sometimes known aspolychloroprene, as it is made up of polymerized chloroprene. Once that chemical reaction is complete, it’s vulcanized for added strength.
Neoprene is best known for itsimpressive strength and flexibility, and itsresistance to many chemicals and harsh environments, making it an ideal material for gasketing in all kinds of industries.
What is Neoprene Resistant To?
Neoprene is celebrated for its resistance topetroleum-based concoctions. This includes manygreases, solvents, and oils. It can also withstand methyl and ethylalcohols, certainsalt mixtures, and some alkaline solutionsas well.
Neoprene can stand up totemperatures as hot as 275° F. Thisheat resistanceis one of its most significant advantages over natural rubber. Itwon’t physically degradewhen exposed to high temperatures for extended periods like natural rubber can. Its heat resistance carries over to actualflame resistance, too.
Neoprene can technically hold up againsttemperatures as low as -50° F. However, it’s essential to understand that it becomes less functional when neoprene is used in temperatures below zero. It physically may hold up, but it’ll likely no longer do what you need it to do, so it’sbest to keep temps on the plus sidewith neoprene.
Take it outside —sunlight and ozoneare no match for neoprene! The material is highly rated for how it holds up inoutdoor environments. Its oxidation rate is low, so it can be counted on for prolonged outdoor use.
In addition to its high resistance properties, neoprene is a veryextensiblematerial. This makes it useful for many different gaskets, but that flexibility has to be considered during the manufacturing process before it’sused to seal something up.
When it’s time tocut neoprene into shape, itselongation must be factored in. If it is stretched out as it’s cut into shape, it’ll fall back to its original form afterward and won’t actually end up in its intended size. Anydie cutting methodshave to be carefully plotted outand performed with neoprene to ensure you’ll get theright shape and sizefor your gasket, which can be tricky.
Ideal Uses for Neoprene
While the flexibility can sometimes pose challenges during the conversion process, the material’s elastic properties can beadvantageous. Neoprene is ideal for something that willfrequently in motionthanks to its elasticity — something that’s active and will requirecushioning and impact absorption.
Its heat, cold, and weather resistance make it a great material to use for items exposed to those conditions. You’ll find neoprene in many电子产品帮助保护sensitive chips and wiring, and its heat resistance allows it to tolerate the gadgetry heating up during use.
Neoprene can be found in too many things to list here, but some of those items include:
- Medical devices
- Musical instruments
- Power transformers
- … And more!
Because neoprene is resistant to a lot and offershigh elasticityandforce resistance, it tends to be amore expensivematerial.
If you’re in the early stages of your project and still working out the budgeting and materials, think aboutwhat exactly you need your gasket to do. Is neoprene really the best option? You don’t need to buy a machete when all you need is a butter knife!
Getting Neoprene Samples Before Production
Neoprene is a high-performing gasket, but it is expensive, so you don’t want to dive into mass production without knowing how neoprene will work with your design and the rest of your materials. That’s why it’s vital toget a sample first, and we can help!
