General properties of polymers

Repeating subunits are the most important properties of polymers. These macro molecules of polymers make up their behavior which is considered to be very important. Formerly the properties of polymers were based on simple and straightforward mechanisms. However, this is not the case now. It is because the polymers have seen advancement in making and new methodologies are developed. It also makes it possible for the polymer users to see new uses which were never thought of in the past. The properties of polymers are divided into following categories:

  • Physical properties
  • Transport properties
  • Mechanical properties

The properties are not limited to what has been mentioned above. There is a huge array which has been developed over the period of time by the chemists. These properties also make it possible for the industries to select the best kind of polymer which is required for manufacture. It is also to be noted that high-temperature polyurethane has completely different set of properties.

Physical properties

These are the most important kind of properties which are considered before putting polymer into use. These are divided into following parts:

Stiffness

This physical property depends upon temperature, stress and time for which the polymer has to endure the overall testing. The stiffness coefficient makes sure whether or not the polymer is got to be used in different applications. It also helps in selecting the best polymer for the kind and type required in making a specific product. The overall stiffness also ensures that the usage of polymer is in line with the requirements of the equipment which is to be made.

Toughness

It is also one of the physical factors. There is some industrial equipment which requires tough and rigid polymers. The toughness factor, therefore, determines that whether or not the equipment should be made from a specific polymer. This toughness also ensures that the temperature and weather endurance is also kept in mind while taking this factor into consideration. High-temperature polymers are the ones which are really tough in appearance.

Transport properties

The movement of molecules within the structure and their velocity is something which is associated with this property. Based on the above stated we will have a good look at underlying factors which make this property very important.

Melting point

Very high-end equipment is made using polymers which mean that the melting point is crucial or else the equipment goes wasted completely.

Mixing properties

It means that how much a polymer is soluble in any solution. The combination of equipment also includes solutions. These work in line with the equipment requirements. The polymer with right mixing properties should be chosen to get the best combo.

Mechanical properties

Tensile and elasticity coefficients are the main ones related to this property. How much a polymer can be stretched and the tensile strength it can endure is calculated before putting it into action. The failure point is also calculated to make sure that the best selection is made for any kind of equipment that is made from a certain type of polymer. The end users are often interested in these properties which make the selection of polymer easy for them overall.
