PC film is the abbreviation of polycarbonate film, the thinnest is 0.03mm thick. It is an amorphous, odorless, non-toxic, highly transparent colorless or yellowish engineering plastic. It has excellent physical and mechanical properties, especially excellent impact resistance, high tensile strength, flexural strength, compressive strength, small creep, size stability; It has good heat resistance and low temperature resistance, stable mechanical properties, dimensional stability, electrical properties and flame retardancy in a wide range of temperature. It can be used for a long time at - 60 ~ 120 ℃; it has no obvious melting point and is in melting state at 220-230 ℃; due to the high rigidity of molecular chain, the resin melt viscosity is high; It is a self extinguishing material with low water absorption, small shrinkage, high dimensional accuracy, good dimensional stability and small air permeability. It is stable to light, but not resistant to ultraviolet light and good weather resistance; It is resistant to oil, acid, alkali, oxidizing acid, amine and ketone. It is soluble in chlorinated hydrocarbon and aromatic solvent. It is easy to cause hydrolysis and cracking in water for a long time. The disadvantage is that it is easy to cause stress cracking due to poor fatigue strength, poor solvent resistance and poor wear resistance.
PC film Classification
PC film can be divided into halogen-free flame retardant PC film, black flame retardant PC film, transparent flame retardant PC film, frosted PC film, transparent PC film, hardened PC film, scratch resistant PC film, printing grade PC film, optical grade PC film and antistatic PC board
Application of PC film
1. Flame retardant PC film is used for power system insulation, disk driver insulation, keyboard insulation, TV / monitor insulation, computer motherboard insulation. It is widely used in the case of flame-retardant panel, electrical appliance panel, electric appliance panel, etc.
2. Printing grade frosted PC film is suitable for special printing, helmet, sign board, protective cover, etc
3. Anti scratch PC film application: window lens of mobile phone, MP3, MP4, DVD, backlight and other electronic products
