What are some physical properties of plastic?
What are some physical properties of plastic?
Plastics can be classified by the chemical process used in their synthesis, such as condensation, polyaddition, and cross-linking. They can also be classified by their physical properties, including hardness, density, tensile strength, thermal resistance, and glass transition temperature.
What are the mechanical properties of plastic?
Plastics with good mechanical properties
- Strength: measure of the resistance of a material to external stress.
- Stiffness: measure of the resistance of a material to deformation.
- Hardness: measure of the resistance of a material to deformation under concentrated compressive load.
What are 5 general properties of plastic?
Properties of Plastics
- They are light in weight and is chemically stable.
- Easily moulded into different shapes and sizes.
- Good insulation and low thermal conductivity.
- Good impact resistance and they do not rust.
- Good transparency and wear resistance.
- Poor dimensional stability and can be easily deformed.
What are three properties of plastic?
What are 3 properties of plastic that make it a useful material?
Plastics are generally low cost, easy to manufacture, durable, strong for their weight, electrically and thermally insulative, and resistant to shock, corrosion, chemicals, and water.

Which plastic is safe?
Nearly everything we eat, drink, or own contains plastic or is contained in plastic. Some plastics, like those that contain BPA or other harmful chemicals, can negatively affect our bodies or the world we live in. Polypropylene, a complex plastic, is generally considered safe for humans.

What are 2 properties of plastic?
What’s the toughest plastic?
Polycarbonate
Polycarbonate is the strongest plastic that is 200 times stronger than glass and is warranted against breakage or cracks. With its high impact strength, it is ideal for structures that are in places where there is snow or hail so that the building is not impacted by such throws.
What are the properties of different plastics?
The properties of plastic are numerous. For the most part, they are: Lightweight with a high strength-to-weight ratio. Can be manufactured inexpensively and mass produced. Water resistant. Shock resistant. Thermally and electrically insulating.
What are the characteristics of plastic?
Plastic has a number of properties that make it a highly useful material. It is transparent, flexible, resistant to water and electricity. It is also generally lightweight and strong and can be moulded into any shape of all sizes. Plastic can mimic fibres from the natural world such as cotton, silk,…
What is plastic property?
Plastic is material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects. Plasticity is the general property of all materials which can deform irreversibly without breaking but, in the class of moldable polymers,…
