Function Of Stearic Acid In Rubber Compounding

Together they form rubber soluble complexes with the accelerators making them better able to react with sulphur to develop cross links.

Function of stearic acid in rubber compounding.

Plasticizer process aid. Akrochem stearic acid tp mixture of stearic and palmitic acids akrochem corp. Stearic acid is the common name for octadecanoic acid which is a saturated fatty acid stearic acid for rubber vulcanization accelerator. These rubber grade stearic acid are used as an activator dispersing agent plasticize and lubricant in rubber compound processing.

First activate the entire curing system. Its name comes from the greek word στέαρ stéar which means tallow the salts and esters of stearic acid are called stearates as its ester stearic acid is. Zinc oxide and stearic acid together form zinc soap improve the solubility of zinc oxide in the compound and with the accelerator to form a complex this complex is particularly lively it reacts with sulfur to produce a very strong vulcanizing agent. Obtained as a result of the variation of stearic acid level from 0 00 to 6 00 pphr.

Rubber grade stearic acid offered by us is sourced from reputed organizations. Stearic acid ˈ s t ɪər ɪ k steer ik s t i ˈ ær ɪ k stee arr ik is a saturated fatty acid with an 18 carbon chain. If you need a higher stearic content check out our 70 stearic acid or our 90 stearic acid. As part of the activating system stearic acid in conjunction with.

The copper substrate should be cleaned pickled and soaked in 10 volume hno 3 for oxide elimination. It is used in relatively low amounts up to 3 0 phr but has a multifunctional effect on their properties and processing. Activators in rubber formulation are typically metal oxides zinc oxide and fatty acids stearic acid. The rubber grade stearic has a lower c18 content than the other stearics we offer ranging between 20 and 55.

Excellent color low iodine. Its primary uses are in more industrial type applications. Dispersing agent and accelerator activator in rubber compounds. This acid is insoluble in water and soluble in ethanol.

The iupac name is octadecanoic acid it is a waxy solid and its chemical formula is c 17 h 35 co 2 h. High purity triple pressed tp stearic acid used in rubber compounding as an activator. The clean sample should be soaked in ethanolic stearic acid solution 0 01 m and 30 v dc should be applied. In doing so they react with active sites in the rubber to form crosslinks between the chains.
