Optimizing Chemical Processing in the Industry
ABOUT CHEMICAL PROCESSING PLASTICS
Plastics have become increasingly popular for use in chemical storage and fluid handling, due to their low cost, durability, and versatility. Plastics such as Nylon, PVC, Fluorinated Ethlyene Propylene (FEP), Acrylic, Polyvinylidene Fluoride (PVDF), Polyetheretherketone (PEEK), and Chlorinated Polyvinyl Chloride (CPVC) all offer excellent resistance to contamination and are chemically resistant.
This makes them ideal for a variety of applications, from pharmaceuticals to potable water and food. Furthermore, these plastics are highly resistant to corrosion, meaning they can be used for a variety of utilities that must remain clean and safe. As a result, plastics are now the material of choice for many chemical storage and fluid handling applications. In addition, plastics are easy to maintain and can be recycled, making them an environmentally friendly option. All in all, plastics make chemical storage and fluid handling more efficient and cost-effective.
