The reliable low liquid level detection system alerts operators when product is running low; adding additional product does not require stopping the machine, so continuous production is possible without any loss of part color. 1.844.4AVIENT www.avient.com Copyright © 2023, Avient Corporation.

These properties, coupled with a wide array of base engineering thermoplastics, deliver the distinct benefits of LubriOne: • Reduced friction and heat buildup between interacting surfaces • Reduced noise and vibration among components in relative motion • Reduced weight and improved design freedom • Lower long–term maintenance costs when grease and other lubricants are eliminated Copyright © 2023, Avient Corporation.
