Function Of Stearic Acid In Rubber Compounding

These rubber grade stearic acid are used as an activator dispersing agent plasticize and lubricant in rubber compound processing.

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. 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 iupac name is octadecanoic acid it is a waxy solid and its chemical formula is c 17 h 35 co 2 h. 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.

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. Dispersing agent and accelerator activator in rubber compounds. Rubber grade stearic acid offered by us is sourced from reputed organizations. As part of the activating system stearic acid in conjunction with.

Together they form rubber soluble complexes with the accelerators making them better able to react with sulphur to develop cross links. 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. The rubber grade stearic has a lower c18 content than the other stearics we offer ranging between 20 and 55.

It is used in relatively low amounts up to 3 0 phr but has a multifunctional effect on their properties and processing. In doing so they react with active sites in the rubber to form crosslinks between the chains. The stearic acid is involved in almost all rubber compounds. Akrochem stearic acid tp mixture of stearic and palmitic acids akrochem corp.

Its primary uses are in more industrial type applications. 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. This acid is insoluble in water and soluble in ethanol.

First activate the entire curing system. Plasticizer process aid. Activators in rubber formulation are typically metal oxides zinc oxide and fatty acids stearic acid. Stearic acid is the common name for octadecanoic acid which is a saturated fatty acid stearic acid for rubber vulcanization accelerator.
