Corrosion Resistant Plastics

Corrosion Resistant Plastics

thyssenkrupp Engineered Plastics stocks a full line of advanced quality chemical resistant plastics that are suitable for any application that requires high corrosion-resistance. When choosing a corrosion resistant plastics product, special attention should be given to the chemicals or corrosive agents the plastic material will be exposed to. Be sure to review any technical information and to thoroughly test materials for the application they will be used in.

There's a wide range of corrosion resistant plastics. The selection of the right material for an application is based on the needs of the end user. Criteria includes what the plastic material will be exposed to, temperatures the plastic will be exposed to, moisture and more. A thyssenkrupp Engineered Plastics salesperson can assist you with material selection. Contact us with your questions today.

Common Corrosion Resistant Plastics


Corzan CPVC (chlorinated polyvinyl chloride) is a high heat, corrosion-resistance plastic material that is most often used in industrial systems and plumbing systems.


Extren® is a corrosion resistant plastic that is typically used in applications where conventional construction materials do not provide economic service life.


This chemical resistant plastic product is chemically inert making it highly resistant to chemicals of virtually any kind.

High Density Polyethylene (HDPE)

HDPE is a corrosion resistant plastic that offers an increased working temperature range, and higher tensile strength when compared to Low-Density Polyethylene (LDPE).

Ultra High Molecular Weight (UHMW)

UHMW is a corrosion-resistant plastic that is also static dissipative and UV resistant.


This chemical resistant plastics product is FDA compliant and does not absorb moisture.


PTFE is a non-stick corrosion resistant plastic that works well in a wide variety of applications.


PVC is a corrosion-resistant plastic polymer that is used in industrial applications including valves, processing tanks, plumbing applications, electrical cable insulation and more.

More About Chemical Resistant Plastics

To learn more about chemical resistant plastics we can take a look at the particular engineering plastic materials that make up the family of chemical resistant materials. These are as follows: 

  • Polyolefin (polyethylene, polypropylene, HDPE, LDPE, UHMW, PP) - Polyolefins are light weight and highly chemical resistant. However, this also makes them unsuitable for applications where bonding is necessary. Due to their resistance means achieving a chemical bond is very likely. Bonds are typically mechanical for polyolefins. They can however, be heat welded.

  • Polyvinyl Chloride (PVC, and CPVC) – Polyvinyl chloride is the oldest of the corrosion resistant plastics. Both PVC and CPVC materials are approximately 35% - 40% heavier and more rigid than polyolefins. By adding a chlorine molecule, CPVC achieves a higher temperature resistance than PVC. Otherwise the two are essentially the same. Unlike polyolefin plastics both PVC and CPVC can be chemically bonded or heat welded and they are available in sheet, rod, tube and profiles.

  • Fluoroplastics or fluoropolymers (PTFE, FEP, PFA, PVDF, PCTFE, ECTFE, ETFE and others) – Fluoroplastics or fluoropolymers are resistant to elevated temperatures, which makes them the proper choice for very hot environments. However, these heat resistant and chemical resistant plastics also tend to be softer than Polyolefin or Polyvinyl Chloride making machining to close tolerances difficult.
