Formable, Deformable, Low Temperature Processing, Low Mass, Impact Resistance, Water Proof, Many Kinds, Plastic Pollution, Plastic Chemicals in Water UV from Sunlight Warm Water Bottles Gulf War Syndrome might have been polymer linings of soda cans reacting at high temperatures producing toxic substances, along with exposure to weapons combusted fumes, including chemical weapons burned in crude fires, releasing toxic fumes troops exposed too, diseases linked to plastic polymer chemical and plastic explosive chemical exposure, cancers, kidney and liver damage, brain damage, metabolic damage, but tire tread erosion the biggest source of microplastic emissions. Imagine, you buy new tires, then over time the tread wears away, where did the tread go? Everywhere!
Hospitals without plastics seems unimaginable, cars, computers, food packages, how could the modern world of low speed impact bumpers and plastic dashboards, BMW even makes the oil pan out of plastic, Glock makes the lower out of Nylon 2, Toyota made the Intake manifold of the 2ZR-FXE in my 22 Corolla Hybrid Sedan LE out of polymer, that "Insulates the block" noting how aluminum intakes heat the incoming air and suck heat away from the head and block, like a giant heat sink, so there are inroads in hot engine parts to make out of ASA and other high temperature resistant plastics, but over time they break down becoming brittle and cracking, notice how carbon fiber epoxy effectively polymer stabilized fibers of carbon. Or how about glass fiber nylon, a very strong fiber reinforced plastic.
Polymers are big business as wire insulators, and how many wires do you think are in the world today. Plastics are non-conductive which means in a power tool they can form the housing without causing connections to short with the internal electronics, switches, brushless motor gear drive, battery connector and wires, safety switches, only works if battery connected correctly, and switch held, or similar. When tools were made of metal, more work and energy went into insulating the internal power electronics of older NiCD pack tools, long before A123 systems nano LFP made dope power tool batteries possible, today CATL of China leads the lithium way while people in the Andes of Peru that live near the lithium brine mining complexes suffer from polluted water and lost access to water, stollen and ruined by lithium operations owned by CATL and other Chinese multinational battery companies.
