HIP/EGP/Diamond grade reflective tape is made based on the principle of refraction and total reflection of cubic cone, the reflective rate is higher. The material can be PET, PC and PMMA (Acrylic), different material with different reflective effect. And the durability is 3-10 years. With the continuous improvement of vehicle speed and the complexity of road conditions, the application market of HIP/EGP/Diamond grade reflective tape will be more and more broad. The signs can be clearly seen in foggy, rainy, snowy weather and at night.
