Applications

EBS is a synthetic wax used as a dispersing agent or internal/external lubricant for benefits in plastic applications to facilitate and stabilize the dispersion of solid compounding materials to enhance processability, to decrease friction and abrasion of the polymer surface, and to contribute color stability and polymer degradation.

It is also used in process industries as release agent and antistatic agent for the production of thermoplastics, and wiring.^[1] It is used in powder metallurgy.^[2]
