Miller Plastics’ custom plastic tanks range in size from less than 1 cubic foot to more than 50 feet long.

Corrosive or harsh chemical environments require tanks with robust features.

We design and construct custom plastic tanks to meet the most demanding specifications.

Many of our custom-fabricated plastic tanks are annealed for maximum strength.

At Miller Plastics, we have 50 years of experience creating single tanks, as well as integrated systems that include process piping or ancillary features for a specific manufacturing process.

Self-supporting tanks can be reinforced with plastic-encapsulated steel bands or internal baffles to minimize sidewall bowing. Welds are smooth and burr-free to minimize sediment buildup and allow for easy cleaning. All edges and components are CNC cut, nothing leaves our shop with saw cut edges, Burrs, or sharp edges.

We manufacture plastic tanks in a wide range of shapes, sizes, and dimensions in corrosion-resistant materials for a variety of uses in harsh environments.

Various material options are available: Kynar (PVDF), Lexan, PP, PVC, CPVC, and More!

All of our plastic tanks are fabricated with 100% virgin American-made materials.

Plastic Tank Materials

  • Polypropylene

Superior corrosion and chemical resistance, very strong and stable material, and excellent fabrication abilities. 200 °F working temperature.

  • Lexan®

Welds well, outstanding mechanical, optical, electrical and thermal properties

  • PVC

Polyvinyl chloride is known for its inexpensive nature and rigid yet flexible properties. Continuous working temperature of 200 °F

  • Polyethylene

Low Density (LDPE), High Density (HDPE) and Ultra High Molecular Weight (UHMW PE), continuous working temperature of 180 °F

  • CPVC

Low-cost, high heat distortion temperature, chemical inertness, and flame and smoke properties. A continuous working temperature of 200 °F.

  • Kynar®

For applications requiring the highest purity, strength, and resistance to harsh acids, solvents, bases, and heat. A continuous working temperature of 235 °F.
