Introduction to PC thin film

PC thin film is a kind of colorless or micro color thermoplastic engineering plastic which is non stereotyped, odorless, harmless and highly transparent. It is mainly used for: flame retardant PC film is used for power system insulation, disk drive insulation, keyboard insulation, TV / display insulation, widely used in electronic components, electrical shell, switch panel, junction box, helmet, label, nameplate, nameplate, protective cover, etc., and also has the advantages of high dimensional accuracy, good dimensional stability and small film permeability.

PC sheet is engineering plastic, which has excellent physical and mechanical properties, especially good impact resistance, high tensile strength, bending strength and compression strength; The creep property is small and the size is stable; It has good heat resistance and low temperature resistance, and has stable mechanical property, dimensional stability, electrical property and flame retardant in a wide range of temperature. It can be used for a long time at -60-120 ℃; There was no obvious melting point, and it was in melting state at 220-230 ℃; Because of the rigidity of molecular chain, the viscosity of resin melt is large; The water absorption is small, the shrinkage rate is small, the size precision is high, the size stability is good, and the permeability of the film is small; It belongs to self extinguishing material; It is stable to light, but not UV light, and has good weather resistance; It is oil resistant, acid resistant, alkali resistant, oxidizing acid and amine and ketone, soluble in chlorinated hydrocarbons and aromatic solvents, and is easy to cause hydrolysis and cracking in water for a long time. The disadvantage is that it is due to the poor fatigue strength, easy to produce stress cracking, poor solvent resistance and poor wear resistance.

PC thin sheet use

1. Flame retardant PC film is used for insulation of power system, disk drive, keyboard, TV / display, computer motherboard. It is widely used in electronic components, electrical shell, switch panel, junction box and charger shell, automobile instruments and panel printing with fire retardant requirements.

2. PC film of printing grade grinding is suitable for special printing, helmets, signs, nameplates, protective covers, etc

3. Anti scratch PC film application: Windows lens of mobile phone, MP3, MP4, DVD, back light source and other electronic products
