Good antistatic PET protective film?

by:LINYANG     2020-03-03
What kind of good antistatic PET film? Everyone knows that, under the same width thick adhesive protective film on the test of tensile strength, elongation at break, heat shrinkage rate, light transmittance, haze, surface resistance of GB test standard. After determination of market professionals, organic silicon pressure sensitive adhesive coating of lam jan antistatic PET protective film antistatic performance. Antistatic PET film polyethylene terephthalate ( PET film) Add with antistatic function compounds ( Antistatic agent) By melt extrusion, two-way stretching made of polyester film, test method is as follows: packaging storage and transportation of GB/T 191 graphic symbol of GB/T 2410 transparent plastic light transmittance and fog degree determination of GB/T 25255 function of optical thin film polyethylene terephthalate ( PET) The tensile properties of thin film method of GB/T 25273 liquid crystal display ( LCD) With film haze method integrating sphere method ASTM D257 insulation method for determination of the dc resistance or conductance antistatic PET film performance indicators project unit thickness FZM 38 target value of 50, 75, 100, 125188 mm length + width of 10 mm target value. Poor + 3 thickness pm< < 3 4 < 6' Eight longitudinal MPa tensile strength & gt; 150 lateral MPa tensile strength & gt; Elongation at break of 120 vertical/horizontal % & gt; Heat shrinkage rate (70 150°C、30分钟) Longitudinal % & lt; 1. 5 < 1. 2 thermal shrinkage of lateral % & lt; 0. 7' 0, 7 transmittance % & gt; 8 8 haze % & lt; 4. 0 surface resistance ( 23 ° C and 3 ° C temperature, relative humidity 50% and 5%) n< 10 n
