What are the advantages of plastics?

Answer 1

plastic are good it is because lots of thing are made from plastic ,Plastic is very good because it can be coloured, melted, shaped, squashed, rolled into sheets or made into fibres. Plastics are used a lot by doctors and dentists because they are hygienic and will not poison our bodies. Plastic fibres are also used to make ropes that are very strong. Fishing lines are made of nylon Many glues are Plastic. Most paints are made from plastic resins. Some, like acrylic house paints and polyurethane varnish are dissolved plastics which dry to form a tough waterproof skin. Fibreglass resin and automotive body fillers are polyester plastics

Answer 2

Plastics don't cost too much and they are strong, which makes them good for production. Plastics can also be molded into many different shapes which is good for creating prototypes.

Resistant

Easy to work with

Plastic is easy to work with and gives many opportunities for moulding.

Plastics can be moulded in many ways - by extrusion, injection-moulding, moulding, press moulding, thermomoulding, blowing, cutting, etc.

Complex products, which in the past consisted of many components can be cast as a single piece.

Custom-made plastic components can be manufactured more quickly and cheaply using considerably less energy than corresponding components in metal.

Environmental advantages

Plastic has environmental advantages

The amount of energy consumed during the manufacture of plastic is low compared with many other materials.

Plastic saves resources - replacing heavy materials in cars, trains, ships and aircraft with lighter plastic components saves fuel. Replacing heavy packaging with plastic packaging saves energy used for transport.

Much plastic waste is collected and regranulated for use in new plastic products - particularly products which do not require the use of raw materials of the highest quality, e.g. waste sacks, compost holders, road signs, beer and mineral water crates, fleece clothing, etc. Plastic which is not recycled can be incinerated, without any environmental problems for most plastics. The incineration of polyethylene, which is the most common type of plastic in use, only generates water and carbon dioxide. Oil is the basis for plastic, which therefore has a high calorific value as a fuel oil, or almost three times that of wood. When oil is used to manufacture plastic, it is useful in many ways, before it is finally incinerated to generate electricity and heat.

Heat insulating

Plastic has a low thermal conductivity

Many types of plastic have a relatively low thermal conductivity. Foam plastic materials such as polystyrene foam, which is for example used as building insulation, have a particularly low thermal conductivity.

High strength

Plastic is strong in relation to its weight

Both the impact resistance and bending strength of plastic are high. This means that if low weight and high strength are both priorities, plastic is often chosen in preference to metal. This applies in the car industry for example, where plastic components are increasingly being used to replace metal and in the aviation industry, where even load-bearing wing components can be manufactured from plastic.

Plastic has a low friction coefficient

This makes plastic ideaLow weight

Plastic is light

The density of plastic is typically 0.9 - 1.4 g/m3, while a lightweight material such as aluminum has a density of 2.7 g/m3 and steel has a density of 6.6 g/m3.

l for cog wheels and bearings.

No electrical conductivity

Plastic has a low electrical conductivity

The conductivity of plastic is 100 trillion times less than copper. Plastic is therefore unique as an insulator of electrical cables, sockets, electrical devices, conducting rails, etc.

No maintenance

Plastic requires minimal maintenance

Plastic tolerates the effects of water and weather and the surface is not degraded by the effects of sun, frost or chemicals. Dirt can be easily removed.

Resistant

Plastic is resistant to solvents and many other chemicals

Depending on the chemical composition of the plastic, it will resist acids, lye, solvents and oil. There are plastic types with good resistance to virtually all chemicals. Plastic is for example used to manufacture containers for chemicals.
kj

the plastics are cheap, durable and easily made into intricate shapes.

Answer 4

it is very cheap to make and is very helpful as you can reuse the plastic over again,

Answer 5

the advanatge of the plastic container is to resical them so that they can re use them.
