Looking for a Hypalon substitute (CSM or CSPE) for your rubber product?

Note that Millathane millable urethanes are NOT chemical nor functional equivalents to Hypalon. Millathane® millable polyurethane rubber can be a Hypalon substitute in some applications, depending on the properties required of the application.

Millable urethane compounds typically have comparable-to-better strength and abrasion resistance compared to Hypalon compounds, as well as improved oil resistance. Millable urethanes generally have inferior heat, acid and alkali resistance compared to Hypalon.

A comparison of the properties of the two polymers is shown in the table below. The comments shown include differentiations between polyether polyurethanes and polyester polyurethanes, where applicable.

Typical Properties

Note: The above polymer comparison is based upon information from several sources and our experience. Specific grades of Hypalon and Millathane millable urethanes, as well as specific formulations, are better for some properties than others, so consult TSE for product and formula recommendations.
 

For applications requiring water resistance, polyether Millathane grades such as Millathane E34, Millathane CM, Millathane E40, Millathane 97 or Millathane 26 may be considered for Hypalon replacement compounds.

For the best oil, abrasion and heat resistance, polyester Millathane grades such as Millathane 76, Millathane 66, Millathane HT or Millathane 5004 might be considered as Hypalon substitutes.
