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.

Obtained as a result of the variation of stearic acid level from 0 00 to 6 00 pphr. As part of the activating system stearic acid in conjunction with. Stearic acid is a saturated fatty acid that can deposit on the surface in special conditions. If you need a higher stearic content check out our 70 stearic acid or our 90 stearic acid.

Akrochem stearic acid tp mixture of stearic and palmitic acids akrochem corp. This acid is insoluble in water and soluble in ethanol. It is used in relatively low amounts up to 3 0 phr but has a multifunctional effect on their properties and processing. The iupac name is octadecanoic acid it is a waxy solid and its chemical formula is c 17 h 35 co 2 h.

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. The rubber grade stearic has a lower c18 content than the other stearics we offer ranging between 20 and 55. Its primary uses are in more industrial type applications.

The result obtained is an indication that stearic acid has varying degree of influence on the physical properties of natural rubber vulcanisates. 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. The copper substrate should be cleaned pickled and soaked in 10 volume hno 3 for oxide elimination. The clean sample should be soaked in ethanolic stearic acid solution 0 01 m and 30 v dc should be applied.

Plasticizer process aid. 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. Rubber grade stearic acid offered by us is sourced from reputed organizations. The stearic acid is involved in almost all rubber compounds.

Excellent color low iodine. Dispersing agent and accelerator activator in rubber compounds. These rubber grade stearic acid are used as an activator dispersing agent plasticize and lubricant in rubber compound processing. In doing so they react with active sites in the rubber to form crosslinks between the chains.
