As we all know, reflective film is a retroreflective material that has been made into a thin film and can be used directly. In 1937, in an American laboratory, the historic first reflective film was born! Reflective films are now used in many places, such as cars, urban roads, ships, etc. The colors are also very complete, including blue, green, red, white, red and white, red and black, etc.
There are two main categories of Reflective Tape. One is reflective powder, which is mainly composed of glass beads. The refractive index of glass beads is very high. When light hits it, it can produce retroreflection.
The other type is called microlattice. Microlattice is a prism-like object with specific properties made of high-molecular polymers. It can also achieve complete retroreflection. Compared with these two things, the second one is The reflectivity is higher than the first type.
