We also completed the divestiture of Performance Products & Solutions (PP&S) and announced an agreement to acquire Clariant’s Masterbatch business. Two months later in December, we announced a definitive agreement to purchase Clariant’s Masterbatch business, a landmark acquisition and a watershed moment for our company. While the Clariant announcement captured headlines to close out 2019, successes within our Products cornerstone began at the onset of the year.

ECCOH™ Low Smoke & Fume Non-Halogen Formulation 5981 UV and chemically resistant thermoplastic for Teck 90 cable outer jackets ECCOH 5981 UV thermoplastic is a cost-effective material for jacketing, combining high environmental stress crack resistance (ESCR), UV performance, good shear strength, and flame-retardant properties for low-voltage, armored cables. The ECCOH 5981 UV grade prevents cracking, absorbs stress, withstands low temperatures, and resists chemicals, helping to reduce damage to cable construction, mitigate risks during installation and use, and avoid costly field repairs. Offering excellent mechanical properties, the ECCOH 5981 UV formulation provides a durable material choice for Teck 90 cables used in demanding locations where safety is paramount.
