All Polyimide High Temperature Flexible Laminate System - Pyralux® HT

Pyralux® HT is a complete all polyimide flexible laminate system with the highest service temperature available today.

The Pyralux® HT system has a service temperature of 225°C, the highest service temperature of any flexible circuit material system available today.  Pyralux® HT is the newest product in the broad Pyralux® portfolio, which has been the trusted material used in flexible circuits for more than twenty years.

The Pyralux® HT system is a complete all polyimide flex laminate system that includes a double-sided copper-clad laminate and a unique all polyimide coverfilm or bonding material that becomes a flexible coverlay after processing.  

The bonding material can be used as a coverfilm or as a bonding material for multilayer flex applications.  Offered in a full range of dielectric thicknesses, Pyralux® HT flexible circuit materials provide designers, fabricators, and assemblers a versatile option for a wide variety of flexible circuit constructions.
