Welcome to the age to reflective materials


Descriptions of common problems of reflective film

Answer:1. The scope of products
YSL series reflective film is mainly used in traffic sign, safety sign, construction Sign, ad banner and other sign and labels.


Notes of heating devices

Answer:1.Multilevel, smooth and soft cushion coat as well as substrate, hot melt film and the ironing equipment of controlled temperature should be prepared.
2.The substrate should be placed smoothly on the cushion coat and try to keep as little tension as possible.


Descriptions of common problems of reflective cloth

Answer:1. Storage
The products should be kept in dry and ventilated room temperature condition, avoiding the effects of high temperature and other destructive factors such as chemical corrosion. The storage period should not exceed one year.


Important notice

Answer:Recently we have found that there are a large number of fake YSL car body reflective labeling products in the market, which have low quality and are sold with low price. The company shall reserve the right of prosecution for any infringement of the products.

Basic Knowledge

Welcome to the age of reflective materials


The second half of high refractive glass beads was aluminized on the surface as retrodirection reflector, which has extremely strong reverse regression reflex performance and can reflect most of the light directly back into the light source, causing reflective  brightness.


High performance reverse reflective material is a high-tech product that integrates high polymer chemical, optics and mechanized equipment, which is one of the seven emerging strategic industries supported by the state.
