Clariant Masterbatches developed nylon compounds that meet demands for tee connectors in landscape irrigation systems.
Dawn Industries Inc. introduced its Kwik-Tap saddle tee to stand out from the competition and allow new ways for making connections. The Arvada, Colo., firm molds Kwik-Tap connectors.
Dawn chose a 15 percent glass-reinforced nylon 6 from Clariant to make the saddle of the tee. The tap component needs to be stronger so it is made from a Clariant 36 percent glass nylon 6.
The nylons contain an internal silicone lubricant for easy removal from the molds.
Dawn regrinds scrap and the longer it molded its initial material and added regrind, the darker the orange got. Clariant's specialty compounding business in Millington, Md., found a heat-stable colorant that allows Dawn to work with its regrind.
