Talk about shading mylar?
The shading Mylar sheet is die-cut (DIECUT) and punched into sheets according to the requirements of the drawings or specified.
There are two kinds of metal and non-metal
1. Commonly used metal Mylar sheets are copper foil Mylar and aluminum foil Mylar, whose main function is to conduct electricity;
2. Non-metallic Mylar is used for insulation. Common materials include PC and PET, which are used for surface protection of membrane switches or electronic and electrical products, or partial insulation.
The so-called Mylar is generally die-cut (DIECUT), punched into sheets according to the requirements of the drawings or specified.
PET polyester film is a biaxially stretched film formed by heating dimethyl terephthalate and ethylene glycol with the help of related catalysts, through transesterification and vacuum polycondensation. Mylar sheet has dimensional stability, straightness and excellent tear strength, heat and cold resistance, moisture resistance, water resistance, chemical corrosion resistance, and has super insulation properties, excellent electrical, mechanical, heat resistance, and chemical resistance.
The so-called light-shielding Mylar sheet is made of light-shielding polyester film (SOMA double matte black PET), which is stamped and formed. The formed shading Mylar sheet.
The finished Mylar is often used for the lens shading part and the camera shading. It is used for insulating gaskets, tapes, leaflets, etc. The manufacturing environment must be a dust-free workshop.
