2. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Thermally processed material is usually totally amorphous, [7] and as a result is highly transparent to visible light, with better light transmission than many kinds of glass. Polycarbonate has a glass transition temperature of about 147 °C (297 °F), [8] so it softens gradually above this point and flows above about 155 °C (311 °F). [9]

4. Reinforced thermoplastic pipe - Wikipedia

   en.wikipedia.org/wiki/Reinforced_thermoplastic_pipe

   Reinforced thermoplastic pipe (RTP) is a type of pipe reinforced using a high strength synthetic fibre such as glass, aramid or carbon. It was initially developed in the early 1990s by Wavin Repox, Akzo Nobel and by Tubes d'Aquitaine from France, who developed the first pipes reinforced with synthetic fibre to replace medium pressure steel pipes in response to growing demand for non-corrosive ...

   en.wikipedia.org/wiki/Glass-to-metal_seal

   Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...

   The material with which a pipe is manufactured often forms as the basis for choosing any pipe. Materials that are used for manufacturing pipes include: Carbon steel; ASTM A252 Spec Grade 1, Grade 2, Grade 3 Steel Pile Pipe; Plastic piping, e.g. HDPE pipe, PE-X pipe, PP-R pipe or LDPE pipe. [11] Low temperature service carbon steel; Stainless steel

7. List of countries by steel production - Wikipedia

   en.wikipedia.org/wiki/List_of_countries_by_steel...

   In 2008, 2009, 2015 and 2016 output fell in the majority of steel-producing countries as a result of the global recession. In 2010 and 2017, it started to rise again. Crude steel production contracted in all regions in 2019 except in Asia and the Middle East. India is the 2nd leading producer of iron and steel industries. [citation needed]
