Polycarbonate(Look Through) Blog of Korea Fire Fighting Corporation

Polycarbonate Cylinder*TM* for Pressure-Containers can be used for Fire Extinguishers, Aerosol Sprays for insect killers, Hair Sprays or Topics and also for Spray(Aerosol) Types of Fire Extinguishers;

Main Characteristics of Polycarbonate: a. Transparent/Nude/Visible/Clean b. Strong enough for +140C -60C c. Weather-resistant d. Impact-Resistant e. Heat-Resistant f. UV Sustainable g. Engineering Plastics from GE, Dow-Chemical, Buyer h. Tested in Aero-spaces by Astronaut Mr. Amstrong in the Moon. i. Newly improved by Lexan Calibre and Mikatron

Application :

1. Fire Extinguishers to be transparent

2. Pressure-Containers, replacing Aluminum or Steel Cans, for Insect Killers or Hair Sprays/Topics

3. Cooking Gas(Butan or LPG) Containers instead of Steel cans

4. Spray types of Fire Extinguishers, containing Halon, AFFF, Dry Chemicals or Liquids(Reinforced Surffectants)

5. Any Other application without Pressure Containing

Other Chemical properties of PC;

1) Impact strength: The impact strength of solid PC sheets is 250 times that of glass, and the impact strength of hollow PC sheets is 80 times that of glass 2) Light weight: the weight of a solid PC sheet is only about half of glass, and the weight of a hollow PC sheet is only about one twelfth at the same thickness 3) Transparency: The light transmission of a 3mm solid PC sheet is 88%, and the light transmission of a6mm hollow PC sheet is 80% 4) UV-protection: A PC sheet is co-extruded with a high-density ultra violet ray that also keeps the PC sheet from discoloring 5) Resistance to weather: A PC sheet has resistance to bad weather and maintains excellent properties in a wide temperature range from -40 to 120oC 6) Inhibiting condensation: When the outdoor temperature is 0oC and the indoor temperature is 23oC, the PC sheet will be condensation up to 80% humidity 7) Thermal insulation: The K-value of glass is 1.2 times that of solid a PC sheet and is 1.7 times that of a hollow PC sheet. PC sheets saves energy while preventing heat loss Sound insulation: The hollow form and polycarbonate resin offers significant advantage to that of glass 9) Flame Resistance: Through testing by the National Center for Quality Supervision & Testing of Fire Building Materials, the material is rated as Class B1 according to QB8624-1997 standards 10) Easy installation: A PC sheet can be bent while hot or cold and can be used on curved roves and windows. The minimum radius of curvature of a PC sheet is 175 times of its thickness. Technical Features: 1) Impact strength: 850J/m 2) Light transmission: 88% 3) Specific gravity: 1.2 g/cm3 4) Coefficient of thermal expansion: 0.065 5) Temperature: -40 to 120oC 6) Heat conductivity: 2.3-3.9 W/m2 7) Tensile strength: >602 Flexural strength: 1002 9) Modulus of elasticity: 2,400Mpa 10) Tensile street at break: >65Mpa 11) Elongation at break: >100% 12) Specific heat: 1.16J/kg.K 13) Heat deflection temperature: 140oC 14) Soundproofing: (6mm solid): 20db
