Chesterton Introduces New Polymer Material That Improves Sealing of Worn & Aging Industrial Cylinders and Presses
Chesterton’s AWC825 Low Durometer Material Technology Minimizes Process Downtime and Extends Equipment Life


GROVELAND, MA – July 29th, 2016

A.W. Chesterton Company is pleased to announce the availability of its new, innovative AWC825 low durometer thermoset polyurethane (EU) technology​. This unique material was specifically designed to improve seal performance associated with worn, scored, aged, or pitted heavy-duty industrial cylinders and presses that cannot be reworked due to size, downtime, or cost.

Chesterton AWC825 has an 85 Shore A hardness that enables it to conform well to surface irregularities and create a positive seal, which helps to extend cylinder mean time between repair (MTBR).

AWC825 is a thermoset material with excellent abrasion and wear resistance that offers improved reliability versus conventional rubber based and polyurethane products and is ideal for use in high reliability applications.

TheAWC825 is a machinable material which provides the flexibility to manufacture any profile to exact equipment dimensions with no tooling costs and same-day availability from local Chesterton SpeedSeal ™ manufacturing centers. Its long-term, elastic memory increases sealing preload, which helps to ensure maximum performance even when exposed to low system pressure.
