A mixture of 1 to 15 wt% of at least one fluorine resin selected from polytetrafluoroethylene (PTFE) or green polychlorotrifluoroethylene (PCTFE) is used.

The acrylic resin is a polymer from an ester such as acrylic acid or methacrylic acid, and is a polymer of methyl methacrylate ester (methyl methacrylate). It is colorless and transparent, and light, especially ultraviolet light, transmits better than ordinary glass (refractive index 1.49). Even when exposed to the outside, it does not discolor, has good chemical resistance, and good electrical insulation and water resistance. If the amount of the acrylic resin used is less than 78 wt%, the transparency and workability may deteriorate. If the amount exceeds 90 wt%, the durability may be deteriorated. Therefore, the amount of the acrylic resin used is preferably 90 To 98 wt%.

The AS (acrylonitrile styrene resin) has been developed to improve the chemical resistance, heat resistance and mechanical strength of polystyrene and is produced by radical polymerization of styrene and acrylonitrile. Major applications are injection molded products such as cold storage containers for refrigerators and table trays.

When the amount of the surfactant is less than 0.01 wt%, it is difficult to expect a synergistic effect of the melt processability. When the amount exceeds 5 wt%, the surfactant may affect the durability of the transparent acrylic plate. Therefore, the amount of polyethylene glycol (PEG) used is preferably limited within a range of 0.01 to 5 wt% with respect to the content of the entire LED QR cord support plate.

If the amount of the fluororesin used is less than 1 wt%, improvement in chemical resistance is unlikely to be improved. If it exceeds 15 wt%, the durability of the entire LED QR code support plate may be affected. The use amount of polyethylene glycol (PEG) is preferably limited within a range of 1 to 15 wt% with respect to the content of the entire LED QR cord supporting plate.
