Sustainable carbon black
A method for producing a more sustainable carbon black (sCB) by producing it from a circular raw material instead of a finite raw material is presented. The method utilizes tire pyrolysis oil produced from end-of-life tires, said to be an attractive alternative feedstock source versus traditional petroleum products.

Truck tire tread compound development using low hysteresis carbon black
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
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.

Cryogenic deflashing for injection molded rubber parts
During rubber injection molding, excess material called flash forms on the surfaces of parts. Unless this unwanted rubber is removed, surface quality suffers. In product assemblies, flash on molded components like rubber gaskets and o-rings can interfere with seating, mating and sealing. A quality injection mold and a skilled injection molder can reduce the amount of flash; but even so-called flashless molds are not immune to this common defect.
