Material Description Common Uses
Polyurethane Polyurethane is mostly used for its resiliency. Because of its durability and variety, it is used in many applications.
  • Bellows
  • Rod Covers
ESD Materials Electrostatic dissipative plastic is frequently used where electrostatic discharge is a threat. This is a great option for applications with flammable compounds or electronics.
  • Small Engine Gas Tanks
  • Hazardous Material Containers
  • Parts for Electronics
Hytrel Hytrel is a thermoplastic polyester elastomer that is both flexible and strong. Certain concentrates of Hytrel allow for UV protection and heat stabilization. The flexibility of the material lends itself well for virtually any custom blow molded part.
  • Bellows that are resilient, reliable, and compress without ripping
  • Any needed UV Protection
Santoprene Santoprene combines the flexibility and low compression set of vulcanized rubber with the manufacturability of thermoplastics. Santoprene allows for excellent environmental protection, light weight blow molding, and lower production costs when compared to other materials.
  • Appliance Parts
  • Rack and Pinion boots
  • Vibration Isolators
Nylon Nylon is a strong, rigid plastic with excellent heat resistance. This makes nylon great for applications where barrier properties are needed. We have various grades depending on your application.
  • Automotive Parts
  • Gas, Fuel, and Hydraulic Tanks
  • Electrical insulating materials
  • Appliance and Plumbing Parts
HDPE HDPE has stronger tensile strength than the lower density polyethylene and is the perfect alternative for specific applications requiring a tougher plastic that is resilient to a wide variety of solvents.
  • Food storage containers
  • Fuel Tanks
Polypropylene Polypropylene blow molds feature low density and good transparency. This material has exceptional sidewall strength at high temperatures and resists cracking with environmental stress. Polypropylene parts are well suited for a wide variety of uses.
  • Laboratory Items
  • Food Containers
  • Disposable Bottles
Polystyrene Polystyrene is economical, easy to process, and easily recycled. This common plastic is versatile and used in many applications.
  • Custom Molded Parts
