New polymer
food contact products introduced

By Bill Hassink
Global Segment Leader Food Grades – DuPont Performance Polymers

DuPont Performance Polymers recently launched a new family of products, designated “FG” (Food Grade), that meet demanding requirements for use in food contact applications. The introduction of these new materials makes the DuPont offering one of the broadest portfolios of engineering plastics and thermoplastic elastomers for food contact applications and is based on the company’s expertise and long experience in polymer science, quality, safety and regulatory compliance.

The DuPont FG portfolio consists of numerous products including DuPont™ Hytrel® TPC-ET, DuPont™ Delrin® POM, DuPont™ Zytel® HTN PPA, DuPont™ Crastin® PBT, DuPont™ Zytel® 6, 6/6 and 6/12 nylon, DuPont™ Rynite® PET and DuPont™ Sorona® EP PTT. All FG products provide compliance with several regional regulations including FDA (Food and Drug Administration), European Food Contact n° 2002/72/EC and GMP (EC) n° 2023/2006, and are available globally. Additional specialty food grade products are being developed from the company’s broad portfolio of performance polymers including its renewably sourced offerings as additional customer needs become evident.

Mycook food processor from the Taurus Group: Components using DuPont materials.The FG, Food Grade, initiative brings to manufacturers the benefits of DuPont’s expertise in science, technology, quality and safety in manufacturing, and regulatory compliance. The company has a broad product portfolio that can meet a wide range of application needs, global manufacturing and supply strength, and long experience in delivering expert assistance to molders. Typical market applications for food-contact approved, high performance polymers from DuPont include food and beverage processing equipment, material handling technology such as conveyor chains and belts, food packaging, household appliances and components for fluid handling. Common criteria for the selection of DuPont engineering polymers in such applications include the replacement of metal for part consolidation, reduced maintenance, self-lubrication and a reduction in weight and noise.

For instance, in a recent application from Spain, a food-approved grade of DuPont™ Zytel® HTN PPA is used to produce three components (the pitcher lid, pitcher support and insulating ring) found in the Mycook food processor from the Taurus Group. The particular grade selected by Taurus, Zytel® HTN FG52G35HSL, retains its mechanical properties such as strength, stiffness and toughness when exposed to heat and moisture in this application over a multitude of cycles and – as its name implies – is approved for use in food applications. The associated benefits for the consumer include the facilitated handling of the pitcher – due to its reduced weight – as well as the reduced risk of breakage or scalding of the user, thanks to the material’s heat insulation performance. Moreover, the attractive polymer components are also easy-to-clean.
