WILMINGTON, Del., May 17, 2006 – DuPont Packaging & Industrial Polymers today announced that it is introducing DuPont™ Entira™ Strong, a polymeric additive that helps improve the performance and processibility of tapes, filaments and films made out of oriented polypropylene and polyester. The addition of Entira™ Strong, even at loading levels as low as 2 to 3 percent by weight, delivers a multitude of performance-enhancing features ranging from increased hot drawability and tenacity to reduced dusting and splitting.
"We are very pleased to be introducing Entira™ Strong as the second product in an innovative new family of modifiers that DuPont launched earlier this month,” said Todd Becker, global market manager, DuPont Packaging & Industrial Polymers. "Not only will Entira™ Strong help processors enhance product performance to better meet end-user needs, it will give them the potential to improve their bottom line."
Studies have shown that dry blending 2 to 3 percent by weight of Entira™ Strong with a base resin enables the stretch ratio to be increased 20 to 30 percent above standard levels, with no reduction in elongation at break. The higher molecular orientation will lead to a tenacity increase and enable manufacturers of geotextiles, flexible bulk containers and multifilaments to consider down-gauging as a means to achieving cost savings without compromising product performance.
Entira™ Strong also reduces dusting, which minimizes blocking and wear on equipment, and helps create a better work environment. And, by reducing splitting, Entira™ Strong helps increase productivity because there are fewer breaks during weaving and strapping operations.
Additional advantages of using Entira™ Strong include: improved softness and smoothness for geotextiles and flexible bulk containers, which makes sewing easier and reduces wear from abrasion; and increased filler acceptance, which helps reduce costs by allowing the use of higher levels of low-cost fillers.
