POLYETHYLENE NAPHTHALATE FILM

摘要

PURPOSE: A polyethylene naphthalate film is provided to ensure excellent scratch resistance, good dimensional stability by the heat, and excellent transparency. CONSTITUTION: A polyethylene naphthalate film is such that 0.2~10 wt% of nano diamond powder is mixed into a polyethylene naphthalate resin based on a solid portion of the whole polyethylene naphthalate resin. The polyethylene naphthalate film has high pencile hardness of 1B~1H, a coefficient of linear thermal expansion less than 20 ppm/°C, and whole light transmittance of 85% or greater.
