The difference between PC material and PP material is as follows:
1.From the appearance, PC is transparent, BOPP is translucent.
2. From the application fields of BOPP and PC.
PC material is polycarbonate, English is polycarbonate, referred to as PC engineering plastics, PC material is actually one of the engineering plastics we call, as a widely used material in the world.
It was used in milk bottle, water cup and soybean milk machine before. It has strong light transmittance and impact resistance, but poor wear resistance.
PP material is polypropylene particles, polycarbonate is polycarbonate in English, referred to as PC engineering plastics.
It is usually used for fresh-keeping box and water cup products, and also for fruit juice beverage bottle, but its light transmittance and impact resistance are poor, but its wear resistance is good;
3. From the advantages and disadvantages of BOPP and PC
Advantages and disadvantages of PC: PC is a kind of amorphous thermoplastic resin with excellent comprehensive performance. It has excellent electrical insulation, extensibility, dimensional stability, chemical corrosion resistance, high strength, heat resistance and cold resistance.
It also has the advantages of self extinguishing, flame retardant, non-toxic and colorable. Compared with metal, its hardness is not enough, which makes its appearance easier to scratch, but its strength and toughness are very good. Whether it is heavy pressure or general wrestling, as long as you do not try to hit it with a stone, it will be long enough.
Advantages and disadvantages of PP: PP material has lower heat distortion temperature (100C), low transparency, low glossiness and low rigidity, but it has stronger impact strength.
The strength of PP increased with the increase of ethylene content. Vicat softening temperature of PP is 150C. Due to the high crystallinity, the surface rigidity and scratch resistance of this material are very good. PP has no environmental stress cracking.
