Stronger Power Grid. Composite materials for power distribution and transmission products. Composite materials for power transmission and distribution products.

PRODUCT OVERVIEW & SELECTION GUIDE INTRODUCING GRIDCORE™ COMPOSITE UTILITY POLES FOR ELECTRIC POWER DISTRIBUTION GridCore™ Composite Utility poles from Avient are engineered to enhance grid resilience as a superior alternative to wood, steel, or concrete electric distribution poles and structures. Lower Total System and Lifecycle Cost GridCore Composite Poles have an expected service life of up to 80 years, compared to 30-40 years for wood poles. Considering the cost of replacing aged, damaged, and failed poles, the longer lifespan of an FRP pole results in total cost savings over the life of the pole.

Home // Power Tool Manufacturer Reduces Production Overhead A leading North American manufacturer of home power tools sought a new solution for producing the “boot,” or soft protective cover, for several of its power saw product lines. At the same time, adding a softer material could increase damping performance, which can help power tool users avoid health issues such as carpal tunnel syndrome and tendinitis related to constant vibration.
