The characteristic of the products and technical indicator:3W glass Cats-eye have good resistant climate,long-lived,Fine wearability,good chemical stability.It can Resist corrode of tyre and sand. Able to bear road surface might run into every solvent,oil rotten.They also have good resistant to acid rain and salt fog, so they can be used in different sternness environment road for a long time.Safety,reliable and warning function strongly.The material is strengthen of high brilliant silicon optical glass is it have silvery white to reflect layer to plate,its reverse reflection coefficient reaches above 80mcd/LX.It can bear high intensity of pressing. 

The glass cats-eye compressed above 157KN. They have already installed and stood for more than one year including large-scale container load vehicle and rolled and tested keeping standing intact by a large scale in testing the road surface.The economic benefits are obvious,worth the masses of users'using widely.This product has already applied for the People's Republic of China and Geneva patent.
