DuPont Adds Two New Grades of Long-Chain Polyamide to Hose and Tubing Offering

DuPont Performance Polymers — Hall 6, Stand C43

DuPont™ Zytel® LC 7000 and Zytel® RS LC 4000 Can Withstand Long Term Aging Performance up to 130°C

Düsseldorf, Germany, Oct. 18, 2013 – DuPont Performance Polymers offers the hose and tube market two new additions to its range of engineering polymers. Both DuPont™ Zytel® LC 7000 and Zytel® RS LC 4000 maintain outstanding impact strength at lower temperatures and offer better aging performance than PA 11 and PA 12.

The new polymers offer a higher amount of flexibility with minimal use of plasticiser for use in low-pressure hydraulic hose and low-pressure pneumatic/hydraulic tubing. Over time, the change in the materials' properties is negligible, even at high temperatures (up to 130°C); primarily because they also only use 5 to 7 percent plasticiser, compared to the incumbent materials that typically contain between 12 to 15 percent..

Both grades offer low permeability, an excellent yield stress/stiffness balance and a broad extrusion processing window, with blow moulding also being a possibility. In comparison to existing market grades, they offer flexibility similar to PA 12 but with significantly better cold impact toughness.

Zytel® LC 7000 and Zytel® RS LC 4000 offer comparable and often superior performance to PA 11 and PA 12 because of a modified polymer backbone.  Zytel® RS LC 4000 is partially derived from renewably sourced ingredients. Due to their enhanced chemistry, they also are suitable for tie-layer-free adhesion to a variety of polymer classes including PA 6, functionalized polyolefins and even Ethylene Vinyl Alcohol (EVOH). They are thus well suited for multi-layer constructions.

According to Enrico Simonato, marketing development consultant at DuPont Performance Polymers, “The industrial hose and tube market is evolving quickly with regard to customer demands, application demands and sustainability targets to help address the huge recycling burden the industry faces. The industry is considering many different variables. The need to reduce weight, lower cost and deliver performance are compounded by operational temperature increases; something that will start to preclude the use of PA 12 above 120°C. On top of this, the industry also is looking for replacement materials with previous PA 12 supply chain issues in mind.”

Zytel® LC 7000 and Zytel® RS LC 4000 offer outstanding aging performance. Over time, the change in their properties is negligible, even at high temperatures (up to 130°C); primarily because they only use 5 to 7 percent plasticiser...compared to incumbent materials that typically contain between 12 to 15 percent.

These new materials also come with the added attraction of customers being able to exploit collaborative application and processing development help from a DuPont matter expert at one of its many innovation centres; where research also is underway to commercialize a translucent version.
