Crastin® Polybutylene Terephthalate For Industrial Applications
DuPont™ Crastin® polybutylene terephthalate PBT resin is available in over 100 grades for cost-effective high performance across a wide range of industrial applications.

Crastin® PBT offers stiffness, toughness as well as excellent electrical insulation properties and beautiful surface finishes.

Crastin® PBT provides excellent dimensional properties and stability versus moisture (from a molding and performance standpoint) and good heat resistance. These properties make it particularly well-suited for lighting bezels, connectors, electrical components, distribution boxes and fiber optic cable jackets. Crastin® PBT is also available in FDA and EU approved grades for food and cosmeticsapplications.

When designing with products that require electrical insulation systems (EIS), DuPont™ Crastin® PBT meets the most stringent electrical insulation standards. DuPont offers the industry’s largest portfolio of EIS pre-approved by Underwriters Laboratories (UL) grades and recognized to IEC standards. 

DuPont™ Crastin® PBT  has superior flow qualities, is easy to process on conventional injection molding machines, and has a wide range of grades designed specifically for low warpage, hydrolysis resistance, and also for blow-molding and extrusion. Latest product families include:

  • Crastin® Super Fast grades to enhance the resin flow to extremely high levels
  • Crastin® Hydrolysis Resistant polyester to ensure maximum product stability, even in extremely severe environments 
DuPont materials science experts can use the properties of Crastin® to help customers gain cost efficiency without compromising on performance.

Superior Moisture Management
Thanks to their exceptional strength, excellent durability and high porosity, DuPont™ Tyvek® materials offer distinct advantages over paper for the active packaging industry. In fact, Tyvek® materials for active packaging combine the best properties of paper, film and fabric into one offering!

For years, active packaging manufacturers have relied on packets, sachets and bags made of Tyvek® that allow for the rapid moisture absorption their customers need to keep a variety of products preserved and dry. What’s more, Tyvek® is a chemically inert material that won’t rot or mildew--even under the most challenging conditions.

Tyvek® provides a durable and versatile material for a wide range of uses, including:

  • Desiccant bags
  • Odor-absorbent packages
  • Fragrance sachets
  • Vapor corrosion inhibitor (VCI) packaging
  • oxygen-scavenging packets
  • Ethylene scavenging sachets
