Silica in tires has enabled greater safety and sustainability in tires for 30 years

RubberWorld 248 Views

hirty years ago, Continental used silica for the very first time in its tread compounds for car tires. The properties of this filler revolutionized the driving safety and energy efficiency of tires. Rolling resistance has been significantly reduced, and braking distances have since been cut by nearly 50 percent. This was made possible by the special surface properties of silica, which can form chemical bonds with the rubber polymer. During vulcanization – the process in which the tire obtains its shape – silica, as well as other components, is responsible for the formation of a very strong network between the rubber molecules. The result is an elastic tire with excellent safety properties.

Truck tire tread compound development using low hysteresis carbon black

RubberWorld 370 Views , 

Performance properties of a surface treated low hysteresis carbon black (Continext-LH) compound in a natural rubber tread formulation are compared with those of a conventional N234 low hysteresis version and show that the new material had significantly improved rolling resistance and directional improvement in damage resistance without negative effects or trade-offs in wet traction and wear resistance.

A new low CO2 reinforcing filler

RubberWorld 352 Views , 

Ferro-Alloy Resources (FAR), a London, U.K. listed mining company with operations in Kazakhstan, recently announced plans to produce a new type of reinforcing filler as a carbon black substitute (CBS). When partially substituted for carbon black in a typical rubber formulation for passenger tire side-walls, there was no significant deterioration of performance in a battery of tests that were conducted, and there were several advantages. Moreover, there is a very significant reduction in CO2e emissions in the production of this material compared with the production of carbon black.

CSRC partners with SHEICO to establish largest eco-friendly carbon black plant in North America

RubberWorld 1016 Views

The board of directors of CSRC group approved a plan to partner with Eco Infinic Co., Ltd., a Thailand subsidiary of SHEICO group. The partnership aims to invest in the recovered carbon black (rCB) business at the original site of Continental Carbon Company (CCC) Phenix plant, jointly developing the North American market for recovered carbon black. This new plant is scheduled to commence production in 2026, and expected to become one of the largest recovered carbon black plants in North America.
