What are the properties and uses of polymers?
Uses of polymers
| Polymer | Properties | Uses |
|---|---|---|
| Poly(chloroethene) ‘PVC’ | Tough, electrical insulator, can be made hard or flexible | Insulation for electrical wires, windows, gutters, pipes |
| Poly(tetrafluoroethene) ‘PFTE’ | Slippery, chemically unreactive | Non-stick coatings for pans, containers for laboratory substances |
What are the properties and structures of polymers?
Polymers always have at least two phases namely, amorphous and crystalline. It is not its Tg, but rather its crystallinity that determines whether the material is a plastic or rubber. The crystals (hard phases) and rubbery (soft phases) make the PE behave as a plastic with toughness, and not as a rubber.
What are 4 properties of polymers?
Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost.

What are 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 the properties of polymers and plastics?
Characteristics of Polymers
- They are resistant to chemicals.
- They are insulators of heat and electricity.
- They are light in mass and have varying degrees of strength.
- They can be processed in various ways to produce fibers, sheets, foams, or intricate molded parts.
What are 10 properties of plastic?
Following are the general properties of plastics.
- Strength. The plastics are sufficiently strong and can be used for load bearing structural members.
- Weather Resistance.
- Fire Resistance.
- Durability.
- Dimensional Stability.
- Chemical Resistance.
- Thermal Resistance.
- Working Conditions.
What are the 8 properties of plastic?
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.
What are the types of polymers?
There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline. They behave in a relatively ductile manner but often have low strength.
