CPVC - 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® - Extren® is a corrosion resistant plastic that is typically used in applications where conventional construction materials do not provide economic service life.
Kynar® - 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).
UHMW – (Ultra High Molecular Weight) UHMW is a corrosion-resistant plastic that is also static dissipative and UV resistant.
Polypropylene – This chemical resistant plastics product is FDA compliant and does not absorb moisture.
PTFE – PTFE is a non-stick corrosion resistant plastic that works well in a wide variety of applications.
PVC – PVC is a corrosion-resistant plastic polymer that is used in industrial applications including valves, processing tanks, plumbing applications, electrical cable insulation and more.
To determine which plastic would best contain extremely corrosive material, we need to consider the chemical resistance and durability of each plastic type. Here's how you can research and evaluate each option:
1. PET or PETE: Polyethylene terephthalate (PET or PETE) is commonly used for beverage bottles. While it is resistant to many substances, it may not be the best choice for extremely corrosive materials. You can research the chemical compatibility of PET/PETE with the specific corrosive substance you are dealing with.
2. HDPE: High-density polyethylene (HDPE) is known for its excellent chemical resistance and toughness. It is widely used in various industries, including pharmaceuticals and chemicals. You can research the chemical resistance properties of HDPE to determine if it can withstand the specific corrosive material you are working with.
3. PVC: Polyvinyl chloride (PVC) is known for its ability to resist chemicals, acids, and bases. However, it may not be suitable for extremely corrosive substances, as some aggressive chemicals might degrade PVC over time. You can research the chemical resistance of PVC and verify its compatibility with the corrosive material you are handling.
4. LDPE: Low-density polyethylene (LDPE) is less chemically resistant compared to HDPE or PVC, but it can still withstand many common corrosive materials. However, it may not hold up well against highly aggressive or corrosive substances. Research the chemical compatibility of LDPE with your specific corrosive material.
5. PP: Polypropylene (PP) is known for its high chemical resistance and is commonly used in chemical laboratories and industries. It offers good resistance to various corrosive substances, but it is still necessary to check its compatibility with the specific corrosive material you are dealing with.
6. PS: Polystyrene (PS) is generally not recommended for containing corrosive materials. It can be affected by many solvents and chemicals, making it less suitable for this purpose. However, if you have a specific corrosive material in mind, you can research its compatibility with PS to confirm its limitations.
In summary, to determine which plastic would best contain extremely corrosive material, consult chemical compatibility charts, material data sheets, or seek guidance from experts familiar with the specific corrosive substance and plastic types. It is crucial to ensure the selected plastic can withstand the corrosive material without degrading or compromising its integrity.
