DuPont™ SHIELD Technology … Science Driven Performance, Exclusively from

DuPontDuPont™ Zytel® PLUS nylon gets its ability to withstand long-term exposure to

heat and chemicals from DuPont™ SHIELD Technology, only from DuPont.

DuPont™ Zytel® PLUS nylon

• Withstands 4,000 hours of exposure to hot air

• Withstands more than 3,000 hours exposure to hot oil and 3000 hours exposure to hot

automotive coolant

• Lasts 2 to 3 times longer than other nylons exposed to aggressive chemicals – such as road

salt – and hot environments

• Retains most of its weld strength after 1000 hours at 210 degrees C, while traditional materials

have dropped to almost zero.

DuPont™ SHIELD Technology … Science Driven Performance, Exclusively from

DuPont

DuPont™ SHIELD Technology combines several innovations,

including a new polymer backbone, polymer

modifications and a special set of additives, to enhance many

performance characteristics. The exact combination and

composition of chemistries are optimized for each product

based on the targeted application.

Research is underway to apply these innovations to additional

engineering plastics

Zytel® PLUS is a family of new products based on DuPont™ SHIELD Technology which

provides outstanding resistance to the harmful effects of high temperature, hot oil,

automotive coolants and road salt. These products retain excellent mechanical

properties for twice as long as current materials while demonstrating exceptional processability and superior surface appearance.

DuPont Renewably Sourced Materials Broadest Portfolio for Engineering Polymers

Sorona® EP Thermoplastic Polymer

• DuPont™ Sorona® EP thermoplastic polymer is similar to the high-

performance characteristics of current PBT materials. PTT is generic

designation. Current feedstock is corn but will change to non-food source.

Hytrel® RS Thermoplastic Elastomer

• DuPont™ Hytrel® RS, thermoplastic elastomer (TPE), offers the flexibility

and elastic recovery of rubbers, the strength of plastics and ease of

processing by conventional thermoplastic methods. Current feedstock is from

biomass.

Zytel® RS 6,10 and 10,10 Long Chain Polyamides

• Comprises all products based on 6,10 and 10,10 including copolymers,

alloys, and reinforced grades. Current feedstock is sebacic acid derived from

caster beans, a non-food crop that requires no maintenance to grow.
