    The scorch safety of these compounds increases with increasing length of the alkyl group: ZDMC < ZDEC < ZDBC and all three have similar high reactivity. Dithiocarbamates are often a good choice for low sulfur cure and low temperature cure and white/transparent or brightly colored rubber goods and as secondary accelerators to speed up cure.

    The two moduli are functions of temperature and frequency. The parameters G and tan, for a typical uncross-linked (unvulcanized) rubber or elastomer, are shown in F ig. 4.8 as a function of temperature (with frequency on the order of 1 Hz). The parameters are plotted against frequency, at a constant temperature, in F ig. 4.9 .

    5 Plastic Additive tandards Accelerants Accelerators are additives that, as the name implies, accelerate or speed up the chemical reaction or the curing of the polymers into the final plastic. Accelerators are also sometimes called promoters. In rubbers, accelerators are used to increase the crosslinking reaction with sulfur in the vulcanization of rubber.

    The frothed structure must be set using a coagulant or a gelling agent. Sodium silicofluoride (Na2SiF6) is widely used in this application. Zinc oxide is also believed to take an active part in the process. Sodium silicofluoride decomposes and forms sodium fluoride (NaF), silicon tetrahydroxide [Si(OH),], and hydrofluoric acid (HP).
