All About Plastics

CORROSION RESISTANT MATERIALS   All our custom designs and products are manufactured from one or more of the following thermoplastic materials.

Rigid Type I PVC
Grade 1 PVC normal impact grade material. Excellent chemical resistance to both acid and alkai solutions for temperatures up to maximum of 140'F. All grades are self-extinguishing. Dark grey standard with additional colors available upon request

Rigid Type II PVC 
 Excellent resistance to acids and alkaline solutions. High impact properties of this material give it superior structural integrity over Type I PVC in larger industrial applications. Light grey standard with additional colors available upon request.

Corzan™ CPVC
 Superior chemical and heat resistance that allows continual operating temperatures up to 194'F. Color is light gray. Also available in off-white as Corzan™ 4910, a fire-safe material that meets Factory Mutual standard 4910 for cleanroom equipment.

Co-Polymer Polypropylene
High-impact grade material which involves the additional copolymerization of propylene and ethylene in a secondary reactor. Conforms to ASTM D4101.82 Class 1 Group 1. Excellent chemical resistance over a wide thermal range. Increased impact resistance over homopolymer polyproplene down to 0'F. Excellent weldability. Ideal material for tank construction.

High-Density Polythylene
Stress-relieved high-density polyethylene material conforming to ASTM D1248-84. Excellent chemical resistance, frictional resistance, and strength up to 160'F. Available in black pipe grade resin (PE 3408) which meets NSF standard 14 and 61 for potable water applications. FDA and USDA approved for food grade applications.


Fabric-Backed Dual-Laminate and Specialty Materials
Bond between the superb mechanical strength of FRP construction. Unplasticized PVC, woven fabric-backed polypropylene, PVDF, ECTFE, PFA, and FEP are available for applications including chemical storage tanks, ducting and processing vessels.

Kynar™ PVDF
Kynar™ is a high molecular weight thermoplastic polymer of vinylidene fluoride. Kynar  possesses superior corrosion, impact and abrasion resistance to almost all known chemicals over a wide range of temperatures (-40'F to above +300'F). It is extremely tough, resistant to UV light and self-extinguishing.

Halar™ ECTFE
Halar™ ethylene-chlorotrifluorethylene products are virtually unaffected by most common corrosive chemicals. ECTFE has excellent chemical and mechanical properties, impact strength, and a broad service use temperature. This polymer offers extremely low permeability to liquids, gases, and vapors.

FEP Fluoropolymer
Fluorinated Ethylene Propylene (FEP) is a thermoplastic fluorocarbon with the same resistance to chemicals as PTFE. This material can be used in a temperature range between -190' to +205'C (-310' to 400').

PFA Fluoropolymer
Perfluoralkoxy Resin (PFA) is a thermoplastic fluorocarbon with similar capabilities and characteristics to FEP. The temperature application range for PFA is -190' to +280'C (-301' to 500').
