Joe Walter considers how the tire curing and vulcanization processes

Today¡¯s cure package for tire compounds is composed of sulfur, an accelerator and an activator. Sulfur, used at 3phr or less, remains the best cross-linking agent for nearly all tire rubber compounds ¨C whether natural or synthetic. Accelerators reduce cure time by increasing the rate of cross-linking compared with sulfur acting alone.

Simulating vulcanization process during tire production to explore

Abstract This paper systematically investigated sulfur transformation during pyrolysis of waste tires by simulating vulcanization process. Three formulas with rubbers, carbon black, ZnO, and typical vulcanization accelerators were prepared by vulcanization and compounded process as simulated tires.

improved tire durability and productivity through compound modifications

Improved Tire Durability And Productivity Through Compound Modifications

Reversion is the degradation of the sulfur network and results in a loss of vulcanizate physical properties. Reversion occurs upon overcure and during cure at elevated temperatures.2 It also continues during the service life of articles where high temperatures can develop through dynamic operation.

non-catalytic pyrolysis of scrap tires using a newly developed two

Non-catalytic pyrolysis of scrap tires using a newly developed two

The aim of this work was to reduce the sulfur content of pyrolysis oil derived from the scrap tire pyrolysis. In this respect, a series of pyrolysis experiments was conducted in both a fluidized bed reactor (one-stage pyrolysis) and a newly developed two-stage pyrolyzer consisting of an auger reactor and a fluidized bed reactor in series (two-stage pyrolysis).

Efficiently treating waste nylon-tire to prepare sulfur and nitrogen

Herein, a typical waste nylon-tire was efficiently treated by pyrolysis, sulfur and nitrogen doped porous carbon material was then firstly prepared from the low-quality char. The activation experiments were systematically conducted at different KOH additive ratios (mass ratios of KOH/char were 2, 3, 4, and 5) and activation temperatures (700 ¡ãC, 800 ¡ãC, and 900 ¡ãC) respectively.

Identification of glycerol as a novel accelerator for sulphur

Among all the polyols studied, glycerol found to be the most efficient accelerator for sulphur vulcanization of unsaturated rubbers. Moreover, from rheometric study glycerol was found to be reversion free and scorch safe accelerator.

on the mechanism of sulfur behavior in rubber compounds

On the mechanism of sulfur behavior in rubber compounds

Under this condition, sulfur, as a eutectic, is in a molten state; due to this, it can diffuse into the polymer matrix. Formation of a eutectic is possible if molten particles of the curing system, containing sulfur, accelerator(s), stearic acid, and zinc oxide, will meet each other inside the rubber matrix during the last stage of compounding.
