Bonding: Use commercially available bonding agents suitable for EPDM , such as Chemlok 236A/205, Chemosil 4100/211, or Cilbond 80/12.
Extruding: Maintain 60°C in the screw and barrel of the extruder. Use of a die heater may be helpful. Extrude through a 60 mesh (minimum) screen.
Sheet Building: A calendering thickness of 1.5mm (0.060") is recommended.
Wrapping: Use Nylon or other high strength wrapping tape. The use of plastic types of tape is not recommended with EPDM.
Curing: A 5-6 hour cure at 145 - 150°C has generally been found to be adequate.
Please note that the above is meant to be a general guideline only. It represents conditions others in the industry have found to be satisfactory. Each manufacturer has to determine themselves as to what works best in their environment.

Chase offers several types of EPDM compounds; the standard EP family is the workhorse, and the EL family is for easy processing, particularly in strip building and in roll finishing.
EPDM's are also available as anti-static or as electrically conductive formulations. In addition, a series of EP formulations are available for textile applications.
EPDM's are especially versatile and can be used across numerous industries, including coating and varnishing, laminating, laser engraving, metal decorating, steel, textile and the wood industries to name but some.
|Chase Elastomers EPDM compounds are
made of the highest quality rubber and from the latest technology available. EPDM rubber
is made from ethylene, propylene and a small amount of a third monomer (for curing
purposes). As a result, its polymer backbone is totally saturated, resulting in
exceptional chemical resistance.
Chase Elastomers EPDMÕs are formulated to meet the requirements of the roller industry and its end use applications. The compounds are designed specifically for the manufacturing processes as used by roller manufacturers. They extrude well and are easy to handle in sheet fabrication.
