2. Expanded polyethylene - Wikipedia

   en.wikipedia.org/wiki/Expanded_polyethylene

   Polyethylene bead foams (including) EPE can be used to replace both polystyrene foam, and both rigid and flexible polyurethane. Uses include cushioning applications, and impact absorption applications including packaging. [4] Consumption of polyethylene for PE foam was estimated at 114x10 6 kg in 2001. The majority was used for non-crosslinked ...

   Section of a block of thermocol under a light microscope (bright-field, objective = 10×, eyepiece = 15×). The larger spheres are expanded polystyrene beads which were compressed and fused. The bright, star-shaped hole at the center of the image is an air-gap between the beads where the bead margins have not completely fused.

6. Filler (materials) - Wikipedia

   en.wikipedia.org/wiki/Filler_(materials)

   Polymer Foam Beads can have a bulk density as low as 0.011 g/cc and range in size from 45 microns to over 8 mm. Common drawbacks to using Polymer Foam Beads in formulated systems include static, temperature, and chemical resistance limitations and difficulty achieving a homogenous blend within a formulated system due to their extremely low bulk ...

7. Plastic extrusion - Wikipedia

   en.wikipedia.org/wiki/Plastic_extrusion

   A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 ...
