A. Its illuminant intensity parameter is 3-4 times that of communications ministry first-class products'. B. Its chemistry capability index conforms to and exceeds the ministry of communications standard C.It aging resistance capability is2-3times the engineering project plastics' and applicable environment temperature is -40~+65°C
1.Good Ability of Reflection: The reflector creates an effect of diamonds, it is so attractive under the lights that the driver can feel the reflection at 150-200m far away. So it is useful for driving in the night.
2.Impact resistance: No cracks are found within the diameter of 6mm from the test point.
3.Load of anti-press: above 160kN
4.Kerosene resistance: no kerosene is penetrated after being dipped in it for more than 10 mins, also with no damage being found.
5.Turpentine resistance: no turpentine is penetrated after being dipped in it for more than 10 mins, also with no damage being found.
6.Alcohol resistance: no alcohol is penetrated after being dipped in it for more than 1min, also with no damage being found.
7.Water-proof performance: no cracks, penetration, wrinkles as well as the similar phenomenon are found after 48 hours dipping in water.
8.Gasoline resistance performance: no cracks, drop-off, scratches, and other damages are found in the road stud after being cleaned for 1 min with 90 or 93# gasoline.
9.Anti salt spray corrosion performance: no discolor, corrosion, or other damages are found after 5 salt spray tests, with each one lasting 22 hours.
10.Weather resistance performance: no cracks, discolors, deformation, bubbles, drops or other damages are found after weather resistance for 1200 hours, with the luminous intensity value above 80% of that before test.
