  Today, I went to the beach front with my children. I found a sea shell and gave it to my 4 year old daughter and said "You can hear the ocean if you put this to your ear." She placed the shell to her ear and screamed.
  There was a hermit crab inside and it pinched her ear.
  She never wants to go back! LoL I know this is totally off topic but I
  had to tell someone!

  PET micro-prismatic reflective tape

  wtorek, 25 lipiec 2023 07:12

  Reflective film is a new type of functional composite material developed in the past 50 years.
  The PET micro-prismatic reflective tape was developed later.
  Because the PET micro-prismatic reflective tape has high brightness, good durability, and low material cost, it also overcomes the shortcomings of the traditional prism reflective material of small effective incident angle, small observation angle, and asymmetric reflected beam, so the PET micro-prismatic reflective tape is also more widely used in road traffic that requires higher brightness.
  
  Here is the content list:
  ●What is the principle and structure of PET micro-prismatic reflective tape?
  
  ●What are the characteristics of PET micro-prismatic reflective tape?
  
  
  What is the principle and structure of PET micro-prismatic reflective
  tape ?
  1. The principle of PET micro-prismatic reflective tape: the reflection principle of
  PET micro-prismatic reflective tape is based on the incidence of
  light in a three-dimensional space from a certain angle, three reflections on three mutually perpendicular planes,
  and then reflecting along the original incident direction. Depending on the manufacturing process, there are two
  types of reflections on the prism surface: one is the (total) reflection at the air-resin interface,
  and the other is the reflection at the aluminum-resin interface.
  
  
  2. Classification by structure: according to the different reflection types, the structure of the PET
  micro-prismatic reflective tape can be divided into two types: coated reflective film and non-coated reflective film.
  There is air behind the uncoated PET micro-prismatic reflective tape, so the
  reflection is mainly total internal reflection, and a stable air layer behind the pyramid is required.
  Therefore, there is a sealing layer in the uncoated reflective film
  to prevent impurities such as moisture and dust from
  entering the air layer. The retroreflective coefficient is reduced.
  A layer of metal, usually aluminum, is plated on the back of
  the reflective tape of the PET micro-prismatic reflective tape, and a layer of reflective film is plated.
  The reflection is mainly performed at the resin-aluminum interface.
  The coated reflective film has no sealing layer. Since the non-plated reflective film needs to be closed, there
  is a supporting wall, viewed from the front, a diamond or hexagonal grid.
  
  
  What are the characteristics of PET micro-prismatic reflective
  tape?
  1. Optical performance: whether it is reflective intensity, wide-angle, etc., PET micro-prismatic
  reflective tape is greatly improved than lens reflective
  film. The reflected light cone of the previous PET
  micro-prismatic reflective tape is asymmetrical, and the
  effective incident angle is small. However,
  through the design of the reflective unit and its array,
  these problems have been solved.
  2. Weather resistance: although the retroreflective coefficient of the PET micro-prismatic
  reflective tape is reduced by 50% after reaching the service life, its retroreflective coefficient can still be
  maintained at 400cd·lx-1·m-2, which is much higher than the other two types of PET micro-prismatic reflective tapes.
  PET micro-prismatic reflective tape has a better reflective effect than glass
  micro-bead reflective film, longer visible distance, and better recognition effect.
  It is generally used for road signs on high-grade highways.
  
  
  With more than 12 years of reflective material production experience, Wenzhou Xiangying Reflective Material Technology Co., Ltd.
  has passed ISO9001 certification and can provide high-quality reflective material production.
  Our company produces many kinds of PET micro-prismatic reflective tape,
  welcome customers to come and purchase.
