The larger circular clear black area represents the larger outer side of the thick one-piece plastic cone "window". Being transparent and durable, PMMA is a versatile material and has been used in a wide range of fields and applications such as rear-lights and instrument clusters for vehicles, appliances, and lenses for glasses.
A laser glass sculpture of a caffeine molecule. A bubblegram (also known as laser crystal, Subsurface Laser Engraving, 3D crystal engraving or vitrography) is a solid block of glass or transparent plastic that has been exposed to laser beams to generate three-dimensional designs inside.
Polyether block amide or PEBA is a thermoplastic elastomer (TPE). It is known under the tradename of PEBAX® ( Arkema ) and VESTAMID® E ( Evonik Industries ). It is a block copolymer obtained by polycondensation of a carboxylic acid polyamide ( PA6 , PA11 , PA12 ) with an alcohol termination polyether ( Polytetramethylene glycol PTMG), PEG ).
The first expanded polystyrene ICF Wall forms were developed in the late 1960s with the expiration of the original patent and the advent of modern foam plastics by BASF. [citation needed] Canadian contractor Werner Gregori filed the first patent for a foam concrete form in 1966 with a block "measuring 16 inches high by 48 inches long with a tongue-and-groove interlock, metal ties, and a waffle ...
An ecobrick is a plastic bottle densely packed with used plastic to create a reusable building block that achieves plastic sequestration.The concept behind ecobricks is to utilize and upcycle post consumer plastic, benefiting our Earth. These plastic bottles are precisely packed with clean and dry used plastic to avoid the growth of bacteria. [1]

In plumbing, the term plunger commonly refers to handheld tools used to clear blockages in drains and pipes. Plumbing plungers consist of a rubber suction cup attached to a stick (shaft) usually made of wood or plastic. A different bellows-like design is usually constructed of plastic.
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.
