WEST CONSHOHOCKEN, Pa. — ASTM International Committee D36, Recovered Carbon Black, has approved its first standard, D8178, which defines important terms in the carbon black industry.
"At this early stage, the rCB (recovered carbon black) industry needs a set of common terminology to effectively communicate to product users and to each other," Bill Cole, director of product management at rCB producer Delta-Energy Group, said.
"As new standards are developed for recovered carbon black, we will be adding new terms to the terminology standard," Mr. Cole said.
Developed recently by several manufacturers, rCB is distinct from the "char" products derived from thermal degradation of rubber compounds, Mr. Cole said. The performance of rCB in rubber applications differs significantly from that of char.
In addition to defining terms, Standard D8178 includes an appendix of ASTM International standards developed by other committees that are recognized as available for use in the rCB industry, ASTM said. This includes the carbon black committee, which was formed in 1956. ASTM Committee D36 on rCB was formed in 2017.
ASTM Committee D36 is next scheduled to meet in Denver June 5-6.
