The wrong mix of chemicals and rubber materials is a quick path to part failure. There are a wide variety of both chemical substances and rubber compounds, which can make identifying the right material rather difficult. Let&#;s break down some common rubber materials and which chemicals they&#;re resistant to (and which ones will cause them to degrade).
Goto HAOZE to know more.
EPDM (Ethylene Propylene Diene Monomer) is a versatile rubber well-regarded for its durability, including resistance to several chemical substances.
Viton (Fluoroelastomer) is a high-performance elastomer built for use in demanding environments. Parts made with Viton are compatible with several different chemicals.
Silicone is a common rubber material used for high-temperature environments and offers resistance to a wide range of chemicals and solvents.
Nitrile (NBR) is one of the best rubber materials available for superior oil resistance, but there are other chemicals that can pose problems.
Like Nitrile, Neoprene is another part commonly used for environments with oil exposure. It can also withstand a variety of other substances, such as methyl and ethyl alcohols.
PVC (polyvinyl chloride) is a thermoplastic known for being a strong, lightweight material that can be either rigid or flexible. PVC is also an appealing option for a variety of chemicals, although some more concentrated substances can cause issues.
TPE (thermoplastic elastomers) is a performance rubber that&#;s processed like plastic. This soft, flexible material offers some chemical resistances, but can struggle with others.

Butyl rubber is an excellent rubber for applications that require shock absorption or gas impermeability. These qualities, along with some notable resistances to chemicals and other environmental challenges make butyl an effective choice for sealing, lining, and mounting.
Natural rubber is an excellent material for parts that demand resistance to abrasion and regular physical contact. However, natural rubber doesn&#;t fare as well when exposed to most chemicals.
While the information above can provide general guidelines, chemical resistances can differ from one specific formulation of rubber to another. Fortunately, Timco helps businesses identify the right rubber material for their performance needs and budget.

Nitrile gloves are used in many industries ranging from healthcare to food. With such a heavy reliance on these gloves, you must understand what dissolves nitrile gloves. Here are a few things that can dissolve nitrile gloves.
Nitrile rubber is resistant to many acids, like sulfuric acid, but it&#;s not immune to acetone. Acetone is a powerful chemical that is used in several different beauty products. Acetone can eat through nitrile gloves reasonably quickly. However, Acetone will not immediately degrade nitriles but will wear them away rather quickly. The danger to you is not so much from the acetone but the melting gloves. It&#;s essential to be careful when using these types of gloves around acetone and other harsh chemicals.
Certain chemicals can soak through nitrile gloves. For example, strong acids and even some alcohols can penetrate these gloves with time. The &#;breakthrough&#; time is the amount of time the chemical takes to get through the glove. Some chemicals have a longer breakthrough time than others. For example, ketones can get through gloves quicker than alcohol can.
Not all gloves are the same. Nitrile gloves and latex gloves are not the same. Nitrile is a type of rubber that is the main component of nitrile gloves. According to the Centers for Disease Control and Prevention, about 10 billion latex gloves are used yearly in the U.S. alone, compared to only 4 billion Nitrile gloves. Nitrile gloves are the premium option when it comes to gloves. They&#;re thicker and can withstand more exposure to chemicals than latex gloves.
What dissolves nitrile gloves? Acetone, ketones, strong acids, and certain alcohols can all dissolve nitrile gloves. The best way to ensure that your nitrile gloves can stand up to the task is to start with a high-quality pair. The best nitrile gloves are tough enough to stand up to many chemicals. Use safe practices when handling chemicals and ensure that you choose suitable gloves for the job. Call Glove America today if you need large quantities of durable nitrile gloves.
