Economic Spin-offs The growth of the automobile industry caused an economic revolution across the United States. Dozens of spin-off industries blossomed. Of course the demand for vulcanized rubber skyrocketed. Road construction created thousands of new jobs, as state and local governments began funding highway design.

Which polymer shows the highest consumption in automotive sector?

The most common ones (approx. 66% of the plastic used in cars) are polypropylene (PP) (32%) (e.g., bumpers, cable insulation carpet fibres, etc.), polyurethane (PU) (17%) (e.g., foam seating, insulation panels, suspension bushings, cushions, electrical compounds, etc.)

Why plastics are used in automobiles?

Polymers have revolutionised the performance, safety, construction and functionality of cars. Parts made of plastics are resistant to corrosion, offer flexibility and resilience for added safety, have very good thermal insulation, reduce noise and allow optimum space utilization.

What plastics are used in automobiles?

More than 70% of the plastic used in automobiles comes from four polymers: polypropylene, polyurethane, polyamides and PVC.

What was the economic and social impact of the automobile?

The automobile gave people more personal freedom and access to jobs and services. It led to development of better roads and transportation. Industries and new jobs developed to supply the demand for automobile parts and fuel. These included petroleum and gasoline, rubber, and then plastics.

Why are car bodies not made of plastic?

Because plastics are expensive. Where cost concerns are high, traditional materials such as metal are used instead, with plastics being reserved for trim, bumper covers, interiors, etc. So, the overall reason you don’t see typical car bodies made from plastic is the cost.

Who is invented plastic?

A key breakthrough came in 1907, when Belgian-American chemist Leo Baekeland created Bakelite, the first real synthetic, mass-produced plastic.

How does polymer have an impact on society?

Polymer has played a greater role in this emerging advancement. These are evident in the modern sophisticated medical, transport, sensor and agricultural equipments now in the market which are made up of metals and modified polymers.

How are polymers used in high temperature applications?

Service temperature limit is a such problem to use polymers in high temperature applications. They have relatively low melting and degredation temperatures, so this can be a limit for use at high temperatures. Some of polymers can degrade on sunlight and some of radiations.

How are polymer properties affect the process technique?

EFFECT OF POLYMER PROPERTIES ON PROCESS TECHNIQUE. While processing thermoplastic melts the following factors should be taken in to account in order both to process efficiently and obtain quality product. Water absorption of raw materials. Physical form of raw material. Thermal stability of polymer. Flow properties. Adhesion of melt to metal.

How are polymers used in the medical industry?

Sport industry safety gear: protective padding, goggles, mouth guards and helmets. Which include shock-absorbent plastic foam and rugged plastic shells (American Chemistry Council, 2019). Medical industry, polymers improve drug bioavailability and the use of artificial skin (IUPAC, 2019).
