Chesterton Introduces New High Performance Polymer Seal Material for Hydraulic Systems
​​Provides Enhanced Sealing Performance

​​Groveland, Massachusetts, USA – October 7, 2013

Chesterton is pleased to announce AWC850, a new, differentiated thermoset polyurethane seal material designed for use in hydraulic systems using ethylene glycol fluids (HFC hydraulic fluids).

The International Organization for Standardization Classification has defined ISO HFC, or a waterglycol hydraulic fluid, as a fire-resistant hydraulic fluid consisting of water and glycol. Some hydraulic systems incorporate hydraulic fluid consisting of water and glycol as a fire retardant media (non-hydrocarbon based, nonflammable). Chesterton's high glycol-tolerant AWC850 exclusive thermoset polyether urethane (EU) material is not only compatible in these fluids but offers superior abrasion resistance and enhanced sealing performance when compared to other elastomer-based seal materials.
