High-intensity grade retro-reflective sheeting with four product series (um1200, um1800, um1800h and um1800l) in line with the technical requirements of retro-reflective sheeting with class two in the national standard gb/t18833-2002 retro-reflective sheeting for road traffic signs , is mainly used for the traffic signs of freeways, class one and class two highways, railways (guide signs, prohibition signs, warning signs and indication signs, etc.), the retro-reflective markings of vehicles, ships and other transportation tools, and is also used to make traffic cones, traffic columns and crash barriers barrels. I. Product features: Um1200 and um1800 (with imported surface film) which have superior flexibility, retro-reflection effect, chromaticity and durability can be used in screen printing. It is easy to carve and convenient to operate. Um1800h and um1800l with imported surface film, bright colors and high tensile strength are suitable to foils for machines; due to good solvent resistance, their surfaces are easy to clean. The retro-reflection coefficient of um1800h is much higher than the requirements of the national standard and the retro-reflection angle is good.
