A new family of nylon products from DuPont Performance Polymers—DuPont Zytel PLUS nylon—delivers high performance levels and maintains those high performance levels much longer than traditional nylons despite exposure to hot oil, hot air, calcium chloride, and other aggressive automotive chemicals, according to the company.
The new family launches with four products primarily targeted at the automotive industry where the drive to take out weight and cost adds up to improved fuel economy and reduced carbon emissions. Additional products are planned for 2010.
DuPont Zytel PLUS nylon gets its ability to withstand long-term exposure to heat and chemicals from SHIELD Technology 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.
The new portfolio launches with:
- Zytel PLUS 95G35 nylon—Requisite, core product delivers good long-term performance at high temperatures (up to 210˚C or even 230°C for shorter periods) PLUS provides great surface appearance, resistance to calcium chloride solutions.
- Zytel PLUS 95G50 nylon—Good long-term performance at high temperatures (up to 210˚C or even 230°C for shorter periods) PLUS better stiffness, creep at high temperatures.
- Zytel PLUS 93G35 nylon—Good long-term performance despite exposure to heat PLUS improved weld lines, good performance in burst tests.
- Zytel PLUS 90G30 nylon—Good resistance to hot engine coolant PLUS excellent properties in contact with water.
Target automotive applications include: charge air coolers, exhaust mufflers, turbo air ducts, engine mounts, resonators, cylinder head covers, oil pans, EGR coolers, oil modules, thermostats, transmission components, and radiator end tanks where calcium chloride resistance is especially important due to road treatments.
