Utility  — Traditional wood and metal utility poles and cross arms are increasingly being replaced by polymer composites because they are non-conductive, durable, and lighter weight than wood or steel, which makes them easier to install. In all cases, polymer composites enhance performance thanks to their resistance to corrosion, heat, weather, and flame.

chemical resistant or fire retardant If needed for the application, TPEs can even be formulated for fire retardant performance.
