Dow announced the introduction of Fingerprint DFDA-7555 NT bimodal polyethylene resin, an evolution of its legacy Fingerprint polyethylene resins. Produced using Unipol II process technology, this medium-density bimodal PE resin helps to address the growing need for materials that contribute to reliable, high-performing and sustainable microirrigation systems that can help increase water productivity, improve crop yields and conserve valuable resources.

Fingerprint DFDA-7555 NT offers better performance and tougher tape for thin wall microirrigation tape applications and profile extrusion applications. Additionally, through the ability to downgauge and incorporate post-consumer resins (PCR) in tape formulation, this product offers the opportunity to make a significant sustainability impact. The tape’s higher stiffness and longevity in long-term and short-term underground tape applications, as well as physical properties enabling the incorporation of materials with reduced properties such as PCR, will play a large role in developing a more sustainable system.

“We are committed to helping our drip irrigation customers and the growers create strong solutions that will benefit their production, bottom line and sustainability efforts for the long-term,” said Stephanie Giles, Customer and Application Development Manager, Dow.

The Fingerprint portfolio of products has utility as a premium product line for microirrigation applications including profile extruded tapes and tubes. This latest Fingerprint grade offers microirrigation tape manufacturers who are looking to meet their customers’ increasing demands several key benefits, including downgauged wall thicknesses with better draw down characteristics for converters when producing tape with a reliable balance of extrusion ease and toughness. Furthermore, the new grade has high tensile and elongation properties, excellent burst strength and better crack resistance.

“Even beyond durability, there is growing worldwide demand for sustainably-made irrigation systems, which is a key component for us as we continue to work with the industry to ensure our value chain partners have the solutions and products they need to meet their customers’ expectations,” said Rachel Anderson, Research Scientist, Dow.
