Features of the Lexan 123R PC
Introduction to the common characteristics of polycarbonate
1. Physical and chemical properties
Pure PPS resin is an amorphous, non-toxic, odorless, olfactory, transparent thermoplastic polymer. The molecular weight is generally in the range of 20000~70000, the relative density is 1.18~1.20, the glass flower temperature is 140~150℃, and the dissolution range 220~230℃
2. Thermal performance
In general engineering plastics, PC has excellent heat resistance, its decomposition temperature is above 300°C, and its long-term high temperature can reach 120°C. At the same time, it has good cold resistance, and its catalytic temperature is as low as -100°C. The temperature range is -60°C~120°C.
3. Mechanical properties:
1. Friction and wear resistance: Compared with other engineering plastics, PC has a larger friction coefficient and poorer wear resistance
2. Creep resistance: outstanding creep performance, better than nylon and polyoxymethylene. The dimensional change and cold flow deformation caused by water absorption are small, which is also an important sign of its dimensional stability.
3. Impact strength: good impact strength and dimensional stability, the disadvantage is poor wear resistance and easy to crack.
4. Fatigue strength: PC’s resistance to cyclic stress is poor
Four, aging resistance and flame resistance
PC has excellent heat aging resistance. If its film is placed in the air for a long time and heated, its performance will change very little. However, if it is exposed to oxygen, sunlight, and water vapor for a long time, it will cause decomposition. PC is flammable and light yellow. Flame, the oxygen index is 25%, and it will extinguish itself when it leaves the flame. Generally, adding halides and other modifications can improve the flame retardancy
5. Electrical properties
PC has extremely small molecules, high glass flower transition temperature, and low water absorption, so it has excellent electrical insulation properties
6. Optical properties
PC is an amorphous substance. Pure PC resin is colorless and transparent, with good light transmission. The light transmittance is affected by poor surface hardness and easy to hair.
Application of Lexan 123R PC
1. Building materials: instead of some inorganic glass, because of the good light transmission performance of PC
2. Car interior: such as various parts, lights, instrument panels, etc.
3. Flying equipment: various parts of the aircraft, the spacecraft is just
4. PC glass bottle: polycarbonate has good impact resistance and transparency, high temperature resistance, and can be made into various water storage bottles that can be repeatedly sterilized
5. Household appliances: brackets, refrigerators, vacuum cleaners, etc.
6. Optical disk manufacturing industry:
7. Highly transparent lenses: such as copier lenses, cameras, microscopes and other transparent lenses
8. Surgical health care: various surgical equipment
