2. Rulon (plastic) - Wikipedia

   en.wikipedia.org/wiki/Rulon_(plastic)

   Rulon 957, green speckled, bearing grade with noise dampening characteristics; Rulon XL, tan, low friction; suitable for aluminium; excellent outgassing characteristics for use in vacuums; Rulon F, green, polymer filled with excellent anti-abrasion characteristics; Rulon 142, aqua, low deformation material for used in linear bearings and slides

3. UL 94 - Wikipedia

   en.wikipedia.org/wiki/UL_94

   UL 94, the Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances testing, is a plastics flammability standard released by Underwriters Laboratories of the United States. [1] The standard determines the material's tendency to either extinguish or spread the flame once the specimen has been ignited.

4. Thermoplastic - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic

   A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. [ 1 ] [ 2 ] Most thermoplastics have a high molecular weight .

5. 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]

6. Low-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/Low-density_polyethylene

   LDPE has SPI resin ID code 4 Schematic of LDPE branching structure. Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene.It was the first grade of polyethylene, produced in 1933 by John C. Swallow and M.W Perrin who were working for Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. [1]

7. FR-4 - Wikipedia

   en.wikipedia.org/wiki/FR-4

   Grade designations for glass epoxy laminates are: G-10, G-11, FR-4, FR-5 and FR-6. Of these, FR-4 is the grade most widely in use today. Of these, FR-4 is the grade most widely in use today. G-10, the predecessor to FR-4, lacks FR-4's self-extinguishing flammability characteristics.

8. Thermoplastic vulcanizates - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic_vulcanizates

   Thermoplastic vulcanizates were first reported in 1962 by A.M. Gessler and W.H. Haslett. [4] In 1973, W.K. Fisher reported the dynamic vulcanization process through his prior work on polypropylene and EPDM rubber-based TPVs with peroxides as a cross-linking agent.

9. Medium-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/Medium-density_polyethylene

   Medium-density polyethylene (MDPE) is a type of polyethylene defined by a density range of 0.926–0.940 g/cm 3. [1] It is less dense than HDPE, which is more common.. MDPE can be produced by chromium/silica catalysts, Ziegler-Natta catalysts or metallocene catalysts.
