    Highly resistant to corrosion and heavy acids, chemical resistant solenoid valves are one of the most vital components in the high-purity liquid transfer process. Manufactured using polytetrafluoroethylene (PTFE), our valves function as both corrosion resistant valves and acid resistant valves. These work well with high purity media, such as 18 megohm deionized water, or with super acidic (low pH) or caustic (high pH) chemicals. At iPolymer, we are worldwide suppliers of engineered high-purity fluid handling products, such as PTFE valves, manifolds, spray guns and connectors. Maintaining purity and chemical resistance are some of the key features of PTFE material, making it ideal for chemical handling. Continue reading  Post ID 269

  • 4 Unusual Applications for PFA Plastic

    PFA Plastic

    PFA plastic hosts several unique properties perfect for a variety of high purity applications. Its excellent chemical resistance against corrosive liquids and smooth low friction surfaces resist deterioration. With a wide temperature range, PFA ensures great stability in extremely hostile environments. Its weldability makes it perfect for fabrication purposes. Engineers and fabricators alike, take advantage of its partial optical clarity during routine inspection for signs of stress within the plastic walls. The polymer chain formation of PFA results in a low dielectric constant which makes PFA a worthy insulator. Undoubtedly, PFA is a powerful and robust plastic within the family of engineered fluoropolymers. Here are just a few unusual applications: Continue reading  Post ID 269

  • Why a Custom Fabrication for Nitric Acid Storage Can Be a Better Solution

    Custom Fabrication for Nitric Acid Storage

    Nitric acid, or HNO3, is a colorless compound that tends to turn brownish-yellow when it decomposes into nitrogen oxides and water. It’s commonly used in the production of grass and plant fertilizers with ammonia to make ammonium nitrate, which is perfect for nitrogen-hungry vegetation. HNO3 works as a compound within rocket propellant, as well as a regular combustible fuel in diesel engines. It’s also used for oxidizing metal, artificially aging maple and pine in woodworking, the manufacture of some clothing dyes, the production of some plastics, and for making explosives such as nitroglycerin and TNT.

  • The Tools You Need for the Safe Preparation of HCL Gas and Other Harsh Chemicals


    Hydrogen Chloride (or HCL gas), is a toxic gas which is important in the semiconductor industry. HCL has  many other uses; for instance, it’s used to produce certain chemicals, metals, petroleum, textiles, and even some food products such as gelatin, soy sauce, and vegetable protein. At room temperature, it’s a colorless gas with a rather pungent smell. When dissolved in water, it is one of the strongest known and toxic acids. And, when it reacts to common metals it yields hydrogen, which can be explosive when it comes in contact with air. Continue reading  Post ID 269

  • 6 Acid Resistant Materials That Can Be Used Effectively in a Lab

    acid resistant materials


    Whether you work in the pharmaceutical industry or chemical manufacturing, finding acid resistant materials to create safe and compliant laboratories or manufacturing facilities is an important part of the job. Luckily, for those of us that work in cleanroom environments, that are plenty of acid resistant materials to choose from and the varying benefits of each can help you figure out which one is best for your specific use case.

    1. PTFE (or Teflon™) – PTFE, also commonly known as Teflon™, is one of the most acid resistant materials available and is commonly used in chemical and pharmaceutical lab applications. Aside from being resistant to many acids used in labs, most people know PTFE (or Polytetrafluoroethylene) as one of the best materials for low friction properties. In fact, it has the second lowest co-efficient of any known solids aside from diamond-like carbon (DLC). What many people don’t know, however, is that PTFE as a lubricant can offer reduced friction in the form of less wear and tear and energy consumption on manufacturing equipment and machinery. And in more stringent healthcare applications, PTFE coatings can minimize the risk of bacteria sticking to hospital equipment, effectively reducing the likelihood of spreading infections.

    2. Hastelloy® – Hastelloy® is a metal superalloy that’s highly resistant to acids, but is primarily used in very niche applications within the aerospace, chemical processing, and industrial gas turbine industries. That’s because Hastelloy® offers the added benefit of working well with high pressure and temperature characteristics. Because Hastelloy® is great for high temperature and high stress environments, like inside of chemical reactors, it’s one of the most expensive acid resistant materials. Given its high cost, it’s not always the most optimal solution for most labs – unless you’re working in a highly corrosive environment.

    3. PVDF – Polyvinylidene (or PVDF) is an acid resistant material (though not as resistant as PTFE) that’s used for a lot of different high purity applications. It’s more flexible than some of its acid resistant counterparts, such as PTFE, and can be injected, molded or welded. Because of its flexibility, it’s often used as an insulator for wires and as piping for high purity liquids. PVDF isn’t as resistant to temperature as other acid resistant materials, so that hinders its ability to work in a wide range of chemical and pharmaceutical lab cases.

    4. Polypropylene – Polypropylene is a thermoplastic polymer that’s rugged and resistant to many acids. It can also function as both a plastic and a fiber, and because of that has one of the largest varieties of applications of all plastics. The fact that it’s relatively cheap to produce also doesn’t hurt. You’ll almost always find polypropylene in small plastic parts for consumer electronics and household appliances, but because of its acid resistant properties, it’s also a popular choice for lab equipment.


    5. PEEK – Polyether ether ketone (PEEK) is a sturdy semicrystalline thermoplastic that can stand up to high temperatures. It can be machined almost like metal, so it’s used in applications that are more demanding, such as electrical cable insulation, piston parts, bearings, pumps, and compressor plate valves. These days, new developments in PEEK processing have given it the ability to have shape-memory behavior, which has a lot of applications in orthopedic surgery. PEEK is more cost prohibitive to work with, though, so it’s usually only used in very specific applications.

    6. PFA – Perfluoroalkoxy alkane (or PFA) is an acid resistant material whose primary claim to fame is its ability to be injection molded. It’s highly corrosion resistant, so it’s most often used in working with aggressive chemicals. It has properties that are very similar to PTFE, but it’s ability to be melt-processed give it an advantage in applications that require injection molding. Because of this, though, it can be expensive to customize.
