Rubber is one of the most important polymeric materials used worldwide. Known for its outstanding elasticity, durability, and resistance to wear and tear, it plays a vital role in industries such as automotive, petrochemical, construction, packaging, and consumer goods.
From tires and seals to hoses and flooring, rubber is the backbone of countless products that require flexibility and long-term performance.
Natural rubber is derived from the latex of the Hevea Brasiliensis tree, which is primarily cultivated in countries such as Thailand, Indonesia, and Malaysia.
After harvesting, the latex is processed through coagulation and vulcanization (adding sulfur to improve elasticity and strength).
Key Properties:
Main Applications:
While natural rubber has great flexibility, it is less resistant to heat, oil, and ozone, leading to the rise of synthetic rubber for more demanding applications
Synthetic rubber is produced from petrochemical feedstocks such as butadiene, styrene, and isoprene through polymerization processes.
It offers the ability to tailor specific properties like chemical resistance, temperature stability, and impact strength based on its composition.
The most common types of synthetic rubber include:
Among these, SBR and PBR are the two most widely used rubbers in the global tire and automotive industry.
FEST supplies rubber grades tailored to different industries. Click and check out the grades.
SBR is a copolymer made from styrene and butadiene monomers.
It is the most commonly used synthetic rubber globally, accounting for over 40% of total rubber consumption.

SBR Types
PBR is a homopolymer produced from pure butadiene monomers.
It is known for its exceptional elasticity and ability to maintain flexibility at low temperatures.
Key Features:
Main Applications:
Property | SBR | PBR |
Structure | Styrene + Butadiene | Pure Butadiene |
Abrasion Resistance | High | Very High |
Elasticity | Moderate | Excellent |
Heat Stability | Better | Moderate |
Main Use | Tires, belts, flooring | Tires, footwear, shock absorption |
Cost | More economical | Slightly higher |
In summary, SBR is preferred for general-purpose applications due to its balance of cost and performance, while PBR is used when superior elasticity and wear resistance are required.
The global rubber industry exceeds 30 million tons annually, with China, the United States, Japan, South Korea, and Germany leading the production of synthetic rubber.
Iran has also emerged as an important player in the regional rubber market.
Thanks to its vast petrochemical resources and growing industrial capacity, the country produces high-quality SBR and PBR used in tires, footwear, and automotive components.
FEST is a trusted supplier of high-quality polymeric and rubber materials, including SBR, PBR, NBR, and various synthetic rubber grades.
