Polyonics has introduced a family of temperature and chemical resistant tapes thatremain dimensionally stable in extreme manufacturing environments, including ultra-high temperatures up to 500° C. The tapes are engineered using Polyonics ThermoGard technology to isolate sensitive, precise and expensive components and products from extreme temperatures and harsh environments.

The polyimide, polyester and aluminum tapes are available in different thicknesses with a variety ofacrylic and silicone adhesives tomeet a wide range of complex applications. The tapes also includeliners that match most diecut processes.

Polyonics understands the chemistry behind the thermal degradation of polymeric materials. Most importantly, Polyonics understands how to engineer composite materials so they remain dimensionally stable and continue to provide superior performanceat ultra-high temperatures. These new high temperature tapes offer manufacturers robust protective solutions where traditional tapes fail.

View ourhigh temperature tape brochurethat outlines the performance and technology behind the tapes and their many practical applications.

Polyimide tapes provide thermal protection up to 500° C. The tapes combine superior electrical, thermal, chemical andmechanicalproperties found in polyimide with proven acrylic and silicone adhesivetechnologies. Polyester tapesoffer effective, lower cost protection for applications involving temperatures of up to 150°C and less harsh environments. The excellent electrical and mechanicalproperties of polyester combined with Polyonics composite technologies provideeffective thermal and electrical insulation. Aluminum tapesyield specific chemical and physical properties including heat dissipation, electromagnetic and RF absorption and provide vapor barriers. They also offer the bestlong term dimensional stability of all the tapes.

In addition to protection from harsh environments, several tapes also include static dissipative (ESD) and flame retardant capabilities. ESD tapes provide a surface resistance in the dissipative range of 10^5to 10^9 ohms that safely dissipates any electrostatic charges before they build up and causedamage to components and products. Flame retardant tapeshelp retard the burn cycle and stop the propagation of flames.
