2. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.

3. Ludowici Roof Tile - Wikipedia

   en.wikipedia.org/wiki/Ludowici_Roof_Tile

   Ludowici Roof Tile, LLC., based in New Lexington, Ohio, is an American manufacturer of clay roof tiles, floor tiles, and wall cladding. The company was established in 1888 with the formation of the Celadon Terra Cotta Company in Alfred, New York. It has created tile for many prominent buildings throughout the United States. [1]

4. Ultra-high temperature ceramic - Wikipedia

   en.wikipedia.org/wiki/Ultra-high_temperature_ceramic

   Ultra-high-temperature ceramics (UHTCs) are a type of refractory ceramics that can withstand extremely high temperatures without degrading, often above 2,000 °C. [1] They also often have high thermal conductivities and are highly resistant to thermal shock, meaning they can withstand sudden and extreme changes in temperature without cracking or breaking.

5. Roof tiles - Wikipedia

   en.wikipedia.org/wiki/Roof_tiles

   Plastic tiles, marketed as composite or synthetic tiles, became available towards the end of the 20th century. Their exact invention date is unclear, but most became available around the year 2000. [59] [60] Plastic tiles are generally designed to imitate slate or clay tiles, and achieve their color through synthetic dyes added to the plastic.

6. Ceramic - Wikipedia

   Silicon nitride rocket thruster. Left: Mounted in test stand. Right: Being tested with H 2 /O 2 propellants. Ceramic material is an inorganic, metallic oxide, nitride, or carbide material. Some elements, such as carbon or silicon, may be considered ceramics. Ceramic materials are brittle, hard, strong in compression, and weak in shearing and ...

7. Roof coating - Wikipedia

   en.wikipedia.org/wiki/Roof_coating

   This means a roof coating actually becomes the top layer of a composite roof membrane and underlying system. As such, the roof coating is the topmost layer of protection for the membrane, receiving the impact of sunlight (both infrared and ultraviolet (UV)), rain, hail and physical damage. Roof Coatings should not be confused with deck coatings.

8. Polymer derived ceramics - Wikipedia

   en.wikipedia.org/wiki/Polymer_derived_ceramics

   The key advantage of this type of ceramic material is the versatility afforded by the use of polymeric precursors in terms of processing and shaping. Polymer derived ceramics can be additively manufactured (3D printed) by means of fused filament fabrication , [ 4 ] stereolithography that uses photopolymerization of preceramic polymers . [ 5 ]

9. Preceramic polymer - Wikipedia

   en.wikipedia.org/wiki/Preceramic_polymer

   The field of preceramic polymers and polymer derived ceramics in general emerged from the requirements in aerospace industries for heat shield materials such as fiber reinforced ceramic / ceramic composite materials. [2] The use of preceramic polymers allows for diverse processing techniques relative to conventional ceramic processing.
