zbec (zinc dibenzyl dithiocarbamate) is a primary accelerator for natural and synthetic rubber. its chemical formula is c30h28n2s4zn. it functions by forming a complex with the sulfur and rubber polymer, which cross-links the polymer chains. this cross-linking process is what gives the rubber its elasticity and strength.

rubber accelerator zbec masterbatch,afte-processing secondary accelerator. can be used as primary in latex. high resistance to hydrolysis, low solubility in rubbers. fast at higher vulcanization temperatures. it has longest anti-scorching capability in the dithiocarbamates. recognized to have low nitrosamine potential. used in sheeting, extrusions and latex, nr, iir, sbr, and epdm.
