Q: Is a plastic a material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and can be molded into solid objects? ¶
Q: Are plastics durable and degrade very slowly? ¶
A: Yes, the very chemical bonds that make them so durable tend to make them resistant to most natural processes of degradation.
Q: Is a plastic derived from the Greek πλαστικός meaning "capable of being shaped or molded", from πλαστός meaning "molded"? ¶
A: Yes, It refers to their malleability, or plasticity during manufacture, that allows them to be cast, pressed, or extruded into a variety of shapes—such as films, fibers, plates, tubes, bottles, boxes, and much more.
Q: Are plastics made substantially from renewable plant materials such as cellulose and starch? ¶
Q: Is a plastic used in packaging and another third in buildings such as piping used in plumbing or vinyl siding? ¶
Q: Are plastics defined chiefly by the organic chemistry of the polymer such as hardness? ¶
A: Yes, and density, and resistance to heat, organic solvents, oxidation, and ionizing radiation.
Q: Was a plastic bakelite, invented in New York in 1907 by Leo Baekeland who coined the term 'plastics'? ¶
A: Yes, Many chemists contributed to the materials science of plastics, including Nobel laureate Hermann Staudinger who has been called "the father of polymer chemistry" and Herman Mark, known as "the father of polymer physics". The success and dominance of plastics starting in the early 20th century led to environmental concerns regarding its slow decomposition rate after being discarded as trash due to its composition of very large molecules.
Q: Are plastics Vinyloop? ¶
A: Yes, and a recycling process and an approach of the industry to separate PVC from other materials through a process of dissolution, filtration and separation of contaminations.
Q: Are plastics discovered from time to time? ¶
A: Yes, and some show promise as being useful for bioremediating certain classes of plastic waste.
Q: Are plastics usually classified by their chemical structure of the polymer's backbone and side chains? ¶
Q: Are plastics the difficulty of automating the sorting of plastic wastes? ¶
A: Yes, and making it labor-intensive.
Q: Are plastics used in an enormous and expanding range of products? ¶
A: Yes, and from paper clips to spaceships.
Q: Are plastics partially crystalline and partially amorphous in molecular structure, giving them both a melting point and one or more glass transitions? ¶
A: Yes, The so-called semi-crystalline plastics include polyethylene, polypropylene, poly , polyamides , polyesters and some polyurethanes.
Q: Are plastics completely amorphous? ¶
A: Yes, such as polystyrene and its copolymers, poly , and all thermosets.
Q: Are plastics associated with the additives? ¶
Q: Are plastics produced from petrochemicals? ¶
Q: Are plastics the plastics that do not undergo chemical change in their composition when heated and can be molded again and again? ¶
Q: Is a plastic incinerated, it increases carbon emissions? ¶
A: Yes, if it is placed in a landfill, it becomes a carbon sink although biodegradable plastics have caused methane emissions.
Q: Are plastics generally made from petroleum? ¶
Q: Are plastics being developed? ¶
Q: Are plastics typically organic polymers of high molecular mass? ¶
A: Yes, but they often contain other substances.
Q: Were plastics bio-derived materials such as egg and blood proteins? ¶
A: Yes, and which are organic polymers.
