Thermoplastic Process Tanks

Thermoplastic materials have been used for several years for the storage of chemicals. They offer excellent corrosion resistance to a range of liquids at ambient temperatures. Thermoplastic materials have a desirable balance of physical properties and chemical inertness. They are tough, flexible materials that are chemically inert.

Corrotech designs and manufactures thermoplastic equipment to meet the customer specific needs. We build our equipment using the latest fabrication technology and techniques in the industry. Our custom fabricated polypropylene equipment will give our customers with the best qualities and versatility for their requirements.

Polypropylene Tanks

    • PP (Polypropylene) Tanks
      Polypropylene is a type of thermoplastic polymer resin that has a chemical designation as C3H6. The benefits of using this type of plastic are that it can be useful in numerous applications including as a structural plastic or as a fiber-type plastic. Corrotech manufactures tanks using Homopolymer (HP) grade and Copolymer (CP) grade as per the needs of the customer. Corrotech procures polypropylene sheets from Roechling, Germany and Reliance, India
      Polypropylene has the following advantages over conventional materials previously used.
      • High chemical and corrosion resistance
      • Easily machined and cut
      • Light weight and rigid
      • Easy to maintain and clean
      • High tensile strength
      • Excellent thermal insulating properties
      • Excellent abrasion resistance
      • Excellent dielectric properties
      • Low moisture absorption
      • Long life span
      Benefits of Polypropylene Tanks
      • Polypropylene provides superior qualities and is the most versatile and cost-effective plastic in comparison to other thermoforming and polyolefin materials.
      • It has good impact strength, surface hardness, dimensional stability and excellent abrasion resistance. Polypropylene is resistant to a wide variety of acids, alkalis and solvent solutions with a temperature range up to 200ºF.
      • The most commonly used colors include natural, black and grey. The black and grey pigments have better UV qualities and an extra UV package is added for outdoor use.
      • Polypropylene is also available in a flame retardant grade.
      • It is USDA approved and meets FDA requirements for food contact.
  • High Density Polyethylene

    High-Density Polyethylene (HDPE) is a polyethylene thermoplastic made from petroleum. A versatile tank construction material high density polyethylene (HDPE) comes in various grades. HDPE resins are characterized by greater toughness, stronger mechanical properties, and higher service temperatures.
    • Highly cost-effective
    • Superb chemical resistance
    • Strength, Resilience & Impact resistance
    • Material is light in weight
    • Non toxic, non taint & odor free
  • Polyvinylidene Fluoride Tanks

    PPVDF is a specialty thermoplastic fluoropolymer, used in applications that need high strength and purity. PVDF is highly pure, provides chemical resistance to acids and bases, abrasion resistance, flame retardants, mechanical strength, impact resistance, thermal stability and ease of processing – making it the ideal choice for the development of highly durable and sustainable lightweight materials.
    Key Benefits of Corrotech PVDF tank
    • mechanical strength and toughness
    • high abrasion resistance
    • heat resistance
    • low permeability to most gases and liquids
    • low weight
    • low thermal conductivity
    • withstands exposure to harsh thermal and chemical conditions
    • unaffected by long-term exposure to ultraviolet radiation
    • resistant to most chemicals and solvents
  • Polyvinyl Chloride Tanks

    Polyvinyl Chloride Tanks
    PVC is a thermoplastic made of 57% chlorine and 43% carbon. The chlorine gives to PVC excellent fire resistance. PVC is clear, colored, rigid or flexible, depending on the added compounds and last application that needs to be achieved. PVC is strong, lightweight, durable and versatile.
