PC is a kind of amorphous thermoplastic resin with excellent comprehensive properties。 It has excellent electrical insulation, extensibility, dimensional stability and chemical corrosion resistance。 It has high strength, heat resistance up to 160 degrees and cold resistance - 60 degrees。 It also has the advantages of self-extinguishing, flame retardant, non-toxic and colorable。 PC plastics can be seen in every corner of your life。 Large-scale industrial production and easy processing also make them extremely cheap。 Its strength can meet all kinds of requirements from mobile phones to bullet-proof glass。 The disadvantage is that its hardness is insufficient compared with metal, 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 don't try to hit it with a stone, it will be long enough。 Diameter up to 600 mm, add acid and alkali preventive agent。
"Pc" management matters needing attention
When polycarbonate is burned, it will produce pyrolysis gas and foam plastic, but it will not ignite. When it is extinguished from the fire source, it will emit a rare and thin odor of phenol. The flame is yellow and light black. The temperature is 140 C and it will soften. When it is melted at 220 C, it can absorb infrared spectrum.
The wear resistance of polycarbonate is poor。 Some polycarbonate devices for wear-prone applications require special surface treatment。 Density: 1。20-1。22 g/cm linear expansion rate: 3。8 *10 cm/cm C thermal deformation temperature: 130 C。 It is not resistant to strong acid or alkali。 Polycarbonate is acid and oil resistant。 Polycarbonate is not resistant to ultraviolet light and alkali。 The wear resistance of polycarbonate is poor。 Some polycarbonate devices for wear-prone applications require special surface treatment。
