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 .
Thermoplastics are made of covalent bond molecule chains, which are held together by weak interactions (e.g., van der Waals forces). The weak intermolecular interactions lead to easy processing by melting (or in some cases also from solution), but also make the polymer susceptible to solvent degradation and to creep under constant load.
Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.
Thermoplastic olefin, thermoplastic polyolefin (TPO), or olefinic thermoplastic elastomers refer to polymer/filler blends usually consisting of some fraction of a ...
The Griffin Museum of Science and Industry (MSI), formerly known as the Museum of Science and Industry, is a science museum located in Chicago, Illinois, in Jackson Park, in the Hyde Park neighborhood between Lake Michigan and The University of Chicago. It is housed in the Palace of Fine Arts from the 1893 World's Columbian Exposition.
Thermoplastic elastomers show advantages typical of both rubbery materials and plastic materials. The benefit of using thermoplastic elastomers is the ability to stretch to moderate elongations and return to its near original shape creating a longer life and better physical range than other materials.
Mechanical properties of short fiber reinforced composites depend critically on the fiber length distribution (FLD) and the fiber orientation distribution (FOD). [3] In particular, the strength of short fiber reinforced composites increases with the increase of the mean fiber length and with the decrease of the mean fiber orientation angle (angle between the fiber axis and the loading direction).
Entrance to the Science Museum of Virginia. A science museum is a museum devoted primarily to science.Older science museums tended to concentrate on static displays of objects related to natural history, paleontology, geology, industry and industrial machinery, etc. Modern trends in museology have broadened the range of subject matter and introduced many interactive exhibits.
