2. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   The type of acrylic used in tanning beds is most often formulated from a special type of polymethyl methacrylate, a compound that allows the passage of ultraviolet rays. Sheets of PMMA are commonly used in the sign industry to make flat cut out letters in thicknesses typically varying from 3 to 25 millimeters (0.1 to 1.0 in).

3. Thermoforming - Wikipedia

   en.wikipedia.org/wiki/Thermoforming

   There is a small but growing medium-gauge market that forms sheet 1.5 mm to 3 mm in thickness. Heavy-gauge forming utilizes the same basic process as continuous thin-gauge sheet forming, typically draping the heated plastic sheet over a mold.

4. High-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/High-density_polyethylene

   HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE. [6]

5. Plastic film - Wikipedia

   en.wikipedia.org/wiki/Plastic_film

   Plastic film is a thin continuous polymeric material. Thicker plastic material is often called a "sheet". These thin plastic membranes are used to separate areas or volumes, to hold items, to act as barriers, or as printable surfaces. Plastic films are used in a wide variety of applications.

6. Picture framing glass - Wikipedia

   en.wikipedia.org/wiki/Picture_framing_glass

   Due to the change in the refractive index, as a light beam travels from air (refractive index of about 1) into glass or acrylic (refractive index of about 1.5) and then back into air, these transitions cause part of the light to be reflected. While "anti-glare" (a.k.a. "non-glare" or matte finish) glass treatments focus on scattering the light ...

7. Forming limit diagram - Wikipedia

   en.wikipedia.org/wiki/Forming_limit_diagram

   A forming limit diagram, also known as a forming limit curve, is used in sheet metal forming for predicting forming behavior of sheet metal. [1] [2] The diagram attempts to provide a graphical description of material failure tests, such as a punched dome test. In order to determine whether a given region has failed, a mechanical test is performed.
