use for tyre making dithiocarbamate accelerators
DE102009059207A1 - Zinc oxide-free, sulfur-crosslinkable
An independent claim is included for tire, where at least a part of tread of tire is made of (I) that is vulcanized with sulfur. Zinc oxide-free, sulfur-crosslinkable rubber mixture, useful for making treads of tires, comprises a synthetic diene rubber and a dithiocarbamate accelerator
Vulcanization Accelerators - The Next Level Solution for Tire
Sulfenamide and Dithiocarbamate Vulcanization Accelerators - Complementing the Mechanical Properties of Vulcanized Rubber. Sulfenamide class accelerators are commonplace in the tire industry in light of delayed action, as well as faster cure rate during vulcanization of rubber compounds containing furnace blacks.
(PDF) Effect of zinc dithiocarbamates and thiazole-based
Several zinc dithiocarbamates (ZDCs) as accelerator derived from safe amine has been exclusively studied in the presence of thiazole-based accelerators to introduce safe dithiocarbamate in the
Substitution of thiurams and dithiocarbamate accelerators
The thiuram and dithiocarbamate accelerators have a large effect on vulcanization, and as a second accelerator and a sulfenamide, the curing time can be shortened. Studies have found that thiuram-based and dimethyldithiocarbamate (ZDMC)-based dithio-amino-based vulcanization accelerators of dithiotetramethyl thiuram (TMTD) produce N in
US3678135A - Co-cure of blend of rubber of low unsaturation
Use of such long chain hydrocarbon dithiocarbamate accelerators as zinc N-dodecyl, N-isopropyl dithiocarbamate in the sulfur cure of blends of rubber of low unsaturation, particularly EPDM, with highly unsaturated rubbers such as SBR, NBR, etc., produces vulcanizates having high tensile strength.
US20050065249A1 - Accelerator system for synthetic
The invention pertains to an accelerator system, such as an accelerator system for synthetic polyisoprene latex. The accelerator system comprises dithiocarbamate and thiourea and can produce synthetic polyisoprene films having a tensile strength of about 3,000 psi to about 5,000 psi at low curing temperatures.

Vulcanization. Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.
Release of dithiocarbamates into artificial sweat from latex
A dithiocarbamate (dtc) salt may be included in the running solvent and aqueous solutions injected onto the column to form the copper dithiocarbamate complex Cu(dtc)2 in situ.
