Renewably Sourced Materials Offer Several Benefits Over Petroleum-Based Products

DuPont today announced the expansion of its renewably sourced portfolio of offerings for the packaging market with the launch of new DuPont(TM) Biomax(R) TPS thermoplastic starch and DuPont(TM) Biomax(R) PTT (polytrimethylterephtalate) injection moldable resin. The launch took place at the global Interpack packaging trade fair here.

"Expanding our portfolio of solutions in renewably sourced packaging is a key strategy for DuPont's Performance Materials segment," said Diane Gulyas, group vice president -- DuPont Performance Materials. "These new offerings demonstrate the power of marrying DuPont's core competency in materials and polymer science with our leadership in bio-based technologies and renewable feedstocks to deliver offerings that provide comparable or better performance than the petrochemical-based materials they replace. They support our commitment to helping customers improve the sustainability of their value chains."

Biomax(R) TPS is a renewably sourced thermoplastic starch for packaging applications. The offering consists of sheet stock that contains 85-90 percent renewably sourced content for thermoformed trays and articles, and resins for injection-molded parts and containers. Biomax(R) PTT contains up to 35 percent renewably sourced content for packaging applications. It is especially suitable for use in injection-molded containers, cosmetic packaging and other parts where polyesters are used.

The new Biomax(R) products join other high-performance polymers made with renewable resources including DuPont(TM) Hytrel(R) RS thermoplastic elastomers, DuPont(TM) Sorona(R) EP thermoplastic resins, DuPont(TM) Selar(R) VP breathable films and renewably sourced grades of DuPont(TM) Zytel(R) long chain polyamides.

Renewably Sourced Materials from DuPont offer several benefits over petroleum-based products. These products reduce dependence on petroleum and, in many instances, reduce the net production of greenhouse gases and energy consumption when compared to incumbent products. With today's innovative technologies, all this can be achieved without compromising performance. Applications for renewably sourced products cross numerous industries and markets. They are used in a wide variety of products including carpeting, fabrics for apparel and interiors, personal care products, automotive components, liquid detergents, food packaging and antifreeze.
