Synthetic Rubber

 

Definition of synthetic rubber
A synthetic polymer that is elastic in nature or elastomer polymer
 
  • Most synthetic rubber is produced as by-products of petroleum.
  • Examples of synthetic rubber is neoprene, styrene-butadiene rubber (SBR) and silicone rubber.
 
Characteristics of synthetic rubber
Elastic
Hard
Resistant to heat
Resistant to chemicals
Resistant to oxidation
Heat insulator
 

Uses of Synthetic Rubber

 
  • With the unique characteristics found in synthetic rubber, various items can be manufactured.
  • Having the advantage of mass production capacity, while not being reliant on the weather or diseases like rubber trees do, makes synthetic rubber the main choice for manufacturing industries.
 
Attribute Uses
Neoprene (polychloroprene)
High heat resistance, oxidation resistance and flame resistance Conveyor belts, petrol rubber hoses and gloves
Styrene-butadiene rubber (SBR)
Abrasion resistance and high heat resistance Tyres and shoe soles
Silicone rubber
High temperature resistance and inert Medical implants, cooking utensils, automotive components and sealants
Thiokol
Oil and solvent resistance Sealants
Nitrile rubber
Oil and solvent resistance Gloves
 

Use of Rubber and the Environment

 
  • Unsustainable use of rubber materials will lead to environmental pollution.
  • Synthetic rubber, particularly, takes a very long time to decompose and makes disposal difficult.
  • Vehicle tyres are among the products of synthetic rubber that need to be disposed of in large quantities.
  • Natural rubber, on the other hand, takes a short time to decompose biologically.
  • Nevertheless, the use of natural rubber is limited due to the natural properties of natural rubber that is less resistant to heat and chemical solvents.
