Zytel® PLUS Performance Data

Science-Driven Performance 
DuPont™ Zytel® PLUS nylon gets it's ability to withstand long term exposure to heat and chemicals from SHIELD Technology, only 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.

Temperature usage for PLUS grades. Click for larger view. 

For example, DuPont™ Zytel® PLUS - can:


  • withstand 4,000 hours of exposure to hot air
  • withstand more than 3,000 hours exposure to hot oil and 3000 hours exposure to hot automotive coolant
  • last 2 to 3 times longer than other nylons exposed to aggressive chemicals – such as road salt – and hot environments
  • retain most of its weld strength after 1000 hours at 210 degrees C, while traditional materials have dropped to almost zero.


These improvements are achieved while maintaining excellent processability and delivering superior surface aesthetics.


The following data charts illustrate the step-change in performance.

Oven Air Aging 

Oven Air Aging Tensile Strength Test at 180 C for PLUS

Heat Aging Tensile Strength at 220 C - PLUS

The new Zytel® PLUS nylon products can retain strength when exposed to 210 degrees C much longer than existing DuPont™ Zytel® PLUS nylon products, which doubled the performance life of traditional nylon.  This resilience makes these products attractive for use in applications exposed to hot air, including EGR coolers, exhaust mufflers, turbocharger air ducts, resonators, cylinder head covers, and exhaust mufflers.  Some grades, such as DuPont™ Zytel® PLUS 95G50 reinforced with 50% glass would provide the higher level of stiffness at the upper temperature classes for charge air cooler applications. 

 

 

Hot Motor Oil Aging 

  Unnotched Charpy Impact at 150 C - PLUS     
New DuPont™ Zytel® PLS95G40DH1T leads the DuPont™ Zytel® PLUS performance in hot oil, showing virtually no drop off in performance despite 5,000 hours exposure to 150 °C hot oil. Other members of the family also show exceptional resistance to impact despite 3,000 hours of exposure to hot oil — where performance of traditional nylon dropped to 50% — making these products attractive for all hot oil applications, oil pans, transmission pans, oil filter modules, rocker covers and many transmission applications. 

 

Hydrolysis Resistance 

 

Hydrolysis resistance - Elongation at 120 C in Water/Glycol medium - PLUS      
Zytel® PLUS 90G30 retains key mechanical properties during exposure to hot water or long-life coolant – again, where traditional nylon products face a 50% drop in performance – making this product ideal for radiator end tanks and thermostat housings.

 

Stone Impact

Stone Impact Test at Room Temperature - PLUS     
DuPont™ Zytel® PLS 95G40DH1T nylon: Designed specifically to meet existing aluminum stone impact and heat -and oil-aging requirements, DuPont™ Zytel® PLS 95G40DH1T outperforms traditional nylons on the market today to help ensure a component such as an exhaust muffler or oil pan withstand impact from gravel and road debris, while maintaining critical sealing function.
