Natural rubber NR has a long service life and high strength, even without reinforcing fillers. The temperature resistance is reasonable + 90C and the material remains flexible to -50C. NR is frequently used in the tire industry, vibration dampers and all kinds of moldings.

Properties NR rubber

  • Good dynamic and mechanical properties
  • Good resistant to aging
  • High strength, elasticity and wear resistance
  • Reasonable temperature resistance
  • Good low temperature flexibility

Natural rubber (natural cis-polyisoprene NR)

Natural rubber has high tensile strength, tear strength, high wear resistance, a very good memory and a low compression set. Both elasticity and compression set are better than with the synthetic alternative, the cis-polyisoprene.

Natural rubber is a strong rubber even without fillers. Temperature resistance is very limited, namely +70 degrees C with peaks direction +100 degrees C. Natural rubber can also be made workable up to -50 degrees C.

Weak sides:

  • The aging and weather resistance is poor.
  • Is not resistant to ozone and oxygen mineral oils

Application:

  • Car tires
  • Vibration dampers

Rubber Natural rubber
Natural rubber is a polymer that appears as an emulsion in the sap of a number of plant species (this sap is known as latex), such as the rubber trees.

Natural rubber is usually produced from latex extracted from the Brazilian rubber tree. About 33% of this juice consists of rubber. The latex is then filtered and diluted with water. The result of this is treated with acid to solidify the rubber particles. The result of this, also called rubber, is rolled into thin slices and dried.

The synthetic production of rubber requires polymerization, a process that is also used in the production of plastics. Examples of synthetic rubbers are chloroprene rubbers, 1.3 butadiene rubbers and butyl rubbers. The raw material for synthetic rubber is petroleum.

The global market for rubber is around 24 million tonnes, of which the share of natural rubber is around 40 to 45%. The most important user of natural rubber is the tire industry, with a share of around 70% and around 12% going to the production of latex gloves.

Rubber is used for car tires, rubber balls, rubber balls, some handles, erasers, etc.

Natural Rubber Latex (a.k.a. NR, Latex, Rubber): This is a natural material, which is created from the saps or rubber trees. It is known to provide more flexibility than nitrile rubber or PVC.

Common characteristics of this material are:

  • Biodegradable
  • Can be worn for long periods of time
  • Good elasticity and strength
  • Can be designed with powder or coatings for easy wear and removal
  • Ideal when working with infectious materials
  • Shorter Shelf Life
  • Typically Degraded by Oil, Resistant to Acid
  • Can cause allergic reactions

 A major disadvantage with latex is that it contains proteins, which can cause skin allergies or more severe reactions in natural rubber sensitive individuals.

The global market for rubber is around 24 million tonnes, of which the share of natural rubber is around 40 to 45%. The most important user of natural rubber is the tire industry, with a share of around 70% and around 12% going to the production of latex gloves.
