Engineered Tapes

As thermal problems come in a wide variety of shapes and sizes, so to must protective tapes. Polyonics understands the chemistry of temperature. How it works, how it affects materials, components and products. Most importantly, Polyonics understands how to engineer composite materials so they remain dimensionally stable at high temperatures and continue to provide superior performance.

Polyonics single coated, linered tapes are offered in three materials; polyimide, polyester and aluminum. Each material comes in a variety of configurations to provide the necessary level of thermal protection for a wide variety of applications. Electrostatic dissipative (ESD) and halogen-free flame retardant tapes are also available.

Dimensional Stability

The performance of engineered tapes is heavily influenced by temperature and its impact on the tape’s dimensions. The chart at right illustrates this relationship for polyimide (PI) and polyester (PET) tapes. The less dimensional change a material exhibits at elevated temperatures the better it will perform at those temperatures. Careful selection of the right tape for each application is imperative.
