Plastic is a kind of material that is made by people and can be formed in almost any shape. Most plastic are strong, long lasting, and lightweight. They resist damage caused by water, heat, chemicals and electricity.
How plastic is made?
Plastics are made from oil. Oil is a carbon-rich raw material, and plastics are large carbon-containing compounds. They’re large molecules called polymers, which are composed of repeating units of shorter carbon-containing compounds called monomers.When did people start to use and make plastic?
The first plastic based on a synthetic polymer was made from phenol and formaldehyde, with the first viable and cheap synthesis methods invented in 1907, by Leo Hendrik Baekeland, a Belgian-born American living in New York state.
What are the properties of plastic chemical and physical?
Plastics generally have: resistance to corrosion and chemicals, low electrical and thermal conductivity, high strength-to-weight ratio, colors available in a wide variety and transparent, resistance to shock, good durability, low cost, are easy to manufacture, resistant to water and have low toxicity.
What are the uses of plastic?
Plastic packaging, with its exceptional barrier properties, light weight, low cost, durability, and transparency, is ideal for medical applications. Today’s most innovative medical procedures are dependent on plastics. Traditionally, metals, glass and ceramics were used for medical implants, devices and supports.
How does plastic harm the environment?
Plastic pollution involves the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat, or humans. Plastics that act as pollutants are categorized into micro-, meso-, or macro debris, based on size. … Plastic pollution can unfavorably affect lands, waterways and oceans.
How can we solve the problem of plastic harming the environment?
So the best thing we can do to protect our waterways is try to keep as much plastic as possible out of the waste stream in the first place. The good news? There are many small ways you can have a big impact.
What are the disadvantages of plastic?
A clear issue that has come with the increased use of plastic materials is the waste that is created with their use. Plastics are not biodegradable and because they are often used only temporarily, they create large quantities of waste in landfills. They have become one of the most wasteful materials that are used today. They are a temporary solution as a material, but become a permanent problem after their disposal.
