1. Unique Manufacturing Capability Polymer Fusion Seals

2. Need a one of a kind Seal?  Exclusive program gives you the freedom to specify unique custom seals without the customary tooling expense –Using Chesterton’s exclusive polymer materials to manufacture a seal.  This unique proprietary process is used to join two or more segments of smaller diameter seals together (fused) to create a continuous (non-split) large diameter seal of any size. –Similar to a metal weld, the integrity of the fused joint is as strong as the base polymer material Polymer Fusion Program

3. Overview  Material options –AWC800 thermoset polymer Equipment is good condition –AWC805 thermoset polymer Worn equipment  Sizes –designed for diameters ≥ 508 mm (20”)  Production –available in Groveland, USA facility  Lead Time –15 production days *Expediting dependent upon on capacity

4. End Product Huge seals custom manufactured for an end user Hydropower industry: ~13’ (3962 mm) diameter seals

5. Getting started Polymer Fusion Program 1.Provide application details to customer service –Complete application questionnaire (inner diameter, outer diameter, height) 2.Engineering will review details –If no tooling exists, a separate quote is provided for a new tooling jig (required for fusion) 3.Customer service will provide a quotation –standard lead time is 15 production days 4.Production is scheduled once a purchase order is received Ask customer service if expediting is required Contact Customer Service #1-978-469-6202
