Interesting Facts about Styrene Butadiene Rubber Chemical
SBR chemical (styrene-butadiene rubber) is a general-purpose synthetic rubber made from a styrene-butadiene copolymer. We can use SBR Chemical in a variety of applications such as vehicle and truck tyres, synthetic rubbers for consumption. Produced from Polyisoprene, it typically works as an abrasion-resistant alternative for natural rubber.
Let’s learn some quick facts about SBR Chemical, first…
- The SBR chemical is a popular substance among shoemakers.
- Styrene-butadiene can assist reduce production costs.
- It is more resistant to abrasion.
- Styrene-Butadiene Rubber has a low heat resistance than synthetic rubber.
- SRB Chemical has a lower resilience to fatigue.
- The natural rubber has low-temperature flexibility and tensile strength than synthetic rubber.
- Styrene-butadiene styrene works as a thermoplastic elastomer.
- The roofing material styrene-butadiene-styrene is excellent.
- What’s more? Unless we add reinforcing fillers, the SRB chemical is weak. With the right fillers’ involvement, this turns into a tough rubber.
Manufacturing of SBR
SBR is a combination of butadiene (CH2=CH-CH=CH2) and styrene (CH2=CHC6H5) that contains around 75% butadiene and 25% styrene. Its final density becomes 0.98 g/cm3 with these two compounds as the emulsion process copolymerizes them. This process involves dispersing, or emulsifying the components in a water solution with a soap-like surface-acting agent. Free-radical initiators, which start the polymerization process, and stabilizers that keep the end product from deteriorating, are among the other elements in this solution.
In addition to that, the Manufacturers of SBR ensure cross-linking of polymer chains during the vulcanization process to meet the required specifications. The repeating ratio of styrene and butadiene along with the polymer chain after polymerization may vary depending on the application.
Key Stats about SBR
The Global Production
In 2019, the global capacity for styrene-butadiene rubber (SBR) was 7.92 million metric tonnes. In the near future, the SBR Chemical sector will significantly increase to 8.57 million metric tonnes by 2024 as per the Google statistics.
Pakistan’s Exports of SBR
Pakistan exports 117.08 USD Dollars’ trade value internationally through SBR material. The average quantity Pakistan exported in 2019 was 30,826 per unit kilogram in Saudi Arabia as per the WITS report.
In addition, according to the United Nations COMTRADE database on international commerce, Pakistan exported 94.11K USD Dollars of styrene polymers in primary forms to Djibouti in February 2021.
The best part? Pakistan exports Styrene Butadiene Rubber polymers to Italy ($135.97K, 100,800 Kg), Oman ($837.05K, 560,531 Kg), Qatar ($90.83K, 31,953 Kg), South Africa ($284.25K, 206,942 Kg), United Arab Emirates ($70.05K, 26,238 Kg).
Applications of SBR Chemical
SBR is primarily applicable in the manufacture of tyres for automobiles and light trucks. Most automobile OEMs are now designing vehicles with excellent performance and durability, which means tyre performance criteria are becoming more severe. SBR’s advantages make it an ideal material for tyre applications. To name a few, these advantages include low rolling resistance, good braking traction, reduced abrasion, and so on.
Besides this, when you acquire a Cold SBR, remember it’s major fact. The fact is SBR isn’t ideal for truck tyre treads or elastic threads used in golf ball manufacturing for lighter-duty tyres and other mechanical items.
Moreover, belts, hoses, seals, and various extruded and moulded products are among the other automotive applications where SBR augment the use cases. Other than that, Industries that require hoses, belts, gaskets, or seals employ SBR in non-tire and non-automotive applications. SBR meets the major requirements for these applications, including end-user service, trouble-free process-ability, bulk pricing, and raw material availability.
What else? Solid wheels, roll coverings, coated fabrics, and electrical (wire and cable) insulation are some of the other usages for SBR.
Last but not least, SBR Chemical is widely applicable in a lot of shoe soles. Rubber sole compositions must meet several criteria, including abrasion and flex resistance, hardness, traction, and form retention.
What is the price of SBR chemicals in Pakistan?
You might be wondering what is the actual price of SBR chemicals, do you? The simple answer is, it depends. When you contact a specialist for the SBR pricing in Pakistan, your contractor can provide you with the most feasible cost based on the application of SBR chemicals. However, those who provide epoxy flooring and waterproofing services in Pakistan may guide you with the right information on SBR chemical prices by inspecting your required work.
Using SBR rubber as a direct replacement for natural rubber is common. It has high abrasion resistance, crack endurance, and aging properties, among other things. You can also find compression set resistance and water resistance sturdy applications with styrene-butadiene.
Other than that, when you opt for the SRB chemical installations, make sure you consider all factors. Two of the most important factors are reinforcing and fillers. SBR has weak strength without reinforcing, low resilience, low rip strength, and worse low-temperature qualities. Therefore, always consider the one without fillers. SBR latex is mixed with cement to be used for construction joints and as a coating material.
