01 Reflective basic knowledge
What is light? Light is an electromagnetic wave
(In vacuum) visible light wavelength range is 380 ~ 780nm;
Infrared light is about 780 ~ 10 ^ 7nm; UV light 1 ~ 380nm;
Shorter than the ultraviolet light X-ray, γ-ray
Light intensity = Candela cd
Illumination: The light on the surface of an object lux
Brightness: The intensity of light from the surface of an object produced by scattering or by reflection at night / Unit area. Cd / m²
Reverse reflection coefficient
The ratio of the luminous intensity coefficient to the surface area of the retroreflector.
Unit for candela per lux per square meter (cd·lx-1·m²)
The retroreflective factor is the most important technical indicator for detecting various reflective materials
Two ways to achieve retro reflex
02 Micro prism Diamond Grade Reflective Tape Structure Principle and Production Technology
Micro prism Reflective Vinyl Structure
Light through the surface into the grade reflective reflector tape,
Into the prism on the corner, and then reflected back from the original direction.
Micro-prism-type retro reflective sheet core technology is the difficulty of the prism base layer of the production, so the product description as a key to explain.
Micro – prism reflective patches Seamless Continuous Production
Extrusion rolling without seams, continuous production process,
Before that, only the United States, Japan, South Korea and a few other countries can achieve production.
WEALLIGHT prism super grade reflective film,
The first time in China using the world’s most advanced extrusion pressure Pattern technology,
To achieve this section of reflective material without seams, large width,
High efficiency and continuous production for China’s related industries to achieve a zero breakthrough.

B mold production
C substrate material
D precision extrusion embossing technology
New Micro – Diamond Grade Reflective Base Film Production Process
Raw materials drying → Plastic melting → Measuring out of the film → Mechanical molding → Cover film Polishing → Finished winding products
New processing technology features
- Application field expansion: new processing technology, can achieve the majority of thermoplastic micro-precision machining, effectively expanding the application of the product
- Significant increase in efficiency: the product to the mechanical molding before, completely belong to the molten state, relatively easy to shape, reducing the mechanical molding time, effectively greatly enhance the production efficiency
Quality control to enhance: raw materials into the finished product,
The entire process of continuous production line,
Reducing the midway link, so that the whole process are controlled state
03 Unique formula and product characteristics
WEALLIGHT Prism diamond grade reflective tape base film,
The use of the world’s leading polycarbonate (PC) and polymethyl methacrylate (PMMA) optical materials as a substrate extruded embossed.
Special weathering formula and twin screw modified equipment to modify,
To maintain the original optical properties of optical materials and mechanical properties on the basis of the material to achieve weather resistance and rheological properties of the upgrade.
Polycarbonate, referred to as PC
PC, a kind of amorphous, odorless, non-toxic, highly transparent colorless or slightly yellow thermoplastic engineering plastics, with excellent physical and mechanical properties, heat resistance and low temperature resistance, can be long-term use at -50 ~ 120 ℃ Light transmission rate of 90% or more, second only to PMMA, and its own has a good weather resistance, reflective material is one of the preferred use of materials.
PC material is an important component of DOT Reflective Tape, one of the necessary materials for DOT certification.
Poly methyl methacrylate: acrylic, commonly known as PMMA
PMMA, density 1.188-1.22g / cm3; highly transparent, light transmittance of 90% -92%, the highest transparency in the plastic;
Glass glass transition temperature 80-100 ℃, the use of temperature -40 ~ 80 ℃, heat relative Low electrical insulation, good weather resistance and insulation;
Their surface hardness is higher, plus hard surface hardness can reach 4-5H, scratch-resistant effect is better.
Common plastic products to distinguish between methods
Comparison of performance of related materials
Reflective tape product features
WEALLIGHT Prism Super Grade Reflective Tape, the use of microcrystalline cube-corner cube prism of the modified reflective design technology, coupled with a large, continuous production process, the product to achieve a wide range of high and reverse the advantages of reverse coefficient while ensuring its surface reverse Coefficient of uniformity and stability.
Product retro-reflection coefficient can meet or exceed the national standard (China) reflective film standard, with 3M, Avery and other internationally renowned brand products comparable.
Reflective film GB standard (China)
According to the national standard seven kinds of reflective film in the minimum inverse reflection coefficient were:
(Test conditions: standard white, -4 ° angle of incidence, 0.2 ° viewing angle cd • lx-1 • m2)
04 Reflector tape weather resistance
Factors affecting the outdoor aging of reflector tape
Affect the reflective tape in the outdoor life of the seven factors:
Dew, humidity, temperature, sunlight, rain, lightning, wind.
The main factor affecting the service life of the reflective film is the ultraviolet radiation in the sun.
Classification and characteristics of ultraviolet light
UV-A: wavelength of 315-380nm, resulting in the degradation of certain polymer molecules; lead to skin tanning, but not burn the skin; can penetrate the glass.
UV-B: wavelength of 280-315nm, in the earth’s surface to the sun, its shortest wavelength, the strongest energy, resulting in most of the polymer degradation; lead to skin burns.
UV-C: wavelength 100-280nm, only the outer layer of the atmosphere; by the ozone layer in the atmosphere to absorb; can be carcinogenic; can be sterilized.
Polycarbonate weather resistance
Polycarbonate (full light transmittance) outdoor placement test
Polycarbonate (yellow index) outdoor placement test
Polyvinyl methacrylate weather resistance
As shown above, WEALLIGHT polycarbonate raw materials after weather modification, after 3 years of outdoor placement test, the light transmittance can still be maintained at more than 85%, while another important optical properties of the yellowing index has not changed, completely Can meet the national standard (China) 50% -80% of the requirements.
The WEALLIGHT polymethyl methacrylate raw materials by weather modification, the optical and mechanical properties can be maintained within 10 years without major changes.
WEALLIGHT quality assurance – Six inspection supervision mechanism
- IQC: raw materials into the company, after a rigorous inspection before the acceptance of storage.
- SBI: Before the use of raw materials, the use of personnel to confirm the quality of raw materials.
- SOP: Staff pre-job training, SOP guide operations, each process after the completion of self-test.
- FQC: special FQC job online inspection.
- OQC: OQC sampling, inspection of qualifying to confirm, the Treasury confirmed a seal can be stored.
- ORT: According to company standards, some special requirements test. The results need to be registered, qualified products need to be stamped before release.
