Polyester

Property Mechanical trait most superior in mediocrity plastic film high tensile strength, appropriate modules of elevation Thermal trail Change in measurement is very small due to wide usage range (-70~-150) Electronic trait Superior in electronic insulation (representable insulator of electric and electronic parts) Chemical resisting property not penetrated by almost all chemicals except high alkalis Moist and water resisting property Moisture and water resisting property is excellent Transparence Excellent in transparency and lustrousness due to flat surface Barrier Penetration of oxygen, carbon gas, water vapor and excellent in gas barrier Stability Hysienically safe, does not use a plasticizer and stabilizer in processing Main Usage Section Thickness(?)
