rubber processing agent zinc diethyl dithiocarbamate effects
Zinc diethyldithiocarbamate | C10H20N2S4Zn
In scratch chamber tests, a small piece of rubber gloves & /zinc diethyldithiocarbamate/ ZDC produced a weal greater than histamine control at 15 min. Patient used different gloves at work when test began & no urticaria appeared. ZDC seemed to be sufficiently absorbed by contact to cause immunologic urticaria & edema of eyelids.
Zinc dibutyldithiocarbamate | C18H36N2S4Zn
Zinc dibutyldithiocarbamate is a dithiocarbamate salt that is the zinc salt of dibutyldithiocarbamic acid. It has a role as an antifungal agrochemical. It has a role as an antifungal agrochemical. It is a dithiocarbamate salt and a zinc molecular entity.
Rubber compounding was performed on a two-roll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a three-stage process. In the first stage, the rubber was mixed with zinc oxide, stearic acid, CB, and Struktol or IPPD. Then the rubber/MLG masterbatch was added to the rubber compound in the second stage.

The highest tensile strength is observed in the zinc (N-benzyl piperazino) dithiocarbamate-accelerated system at 3:6 mM ratios. process for waste rubber powder (WRP) was investigated in this
Zinc dimethyldithiocarbamate is a coordination complex of zinc with dimethyldithiocarbamate.It is a pale yellow solid that is used as a fungicide, the sulfur vulcanization of rubber, and other industrial applications.

THE RUBBER INDUSTRY: REFLECTIONS ON HEALTH RISKS
Reference to Fig. 1.1 will indicate that the other main health hazards likely to be encountered in rubber processing derive from exposure to dusts and fumes. Bales of natural rubber are covered in talc which is released when they are handled and cut. Talc is also a commonly used anti-stick agent, especially in tube extrusion.
The Mechanism of Zinc(II)-Dithiocarbamate-Accelerated
These studies have revealed that, in a three-stage process, ZDMC exhibits a unique combination of catalytic activity: (1) It mediates the reaction between sulfur and rubber. This is achieved by incorporating sulfur atoms in the zinc-dithiocarbamate ring and inducing their insertion into an allylic C−H bond via an ene-like reaction.
Nanocomposites of NR/SBR Blend Prepared by Latex Casting
High ammonia concentrated NR latex (60% dry rubber content, DRC), aqueous solution of potassium oleate (10 wt%) and potassium hydroxide (10 wt%), and aqueous dispersion of sulfur (50 wt%), zinc oxide (50 wt%), zinc diethyl dithiocarbamate (50 wt%), and Wingstay L antioxidant (50 wt%) were supplied by the Rubber Research Institute of Thailand.
