The Effect of Stearic Acid on Curing Characteristic

The mixing of organoclay into natural rubber by using melts compounding method. Stearic acid was added into rubber by insitu and exsitu as a purpose for increasing exfoliation of organoclay in natural rubber matrix. The result showed that maximum torsion (Smax) and difference torsion (Smax-Smin) reduced with increasing of stearic acid loading.

How does stearic acid work in skin cleansers?

But it's in skin cleansers that stearic acid really takes a starring role. Stearic acid is one of many fatty acids that occur naturally in various plants and animal derivatives. It's found in such products as animal tallow, cocoa butter and vegetable fats. When it's used in cosmetic products, stearic acid primarily fulfills the role of a thickener or hardener.

Why is sulphur used for the vulcanization of rubber?

Aug 21, 2017Sulphur alone cannot be used for vulcanisation. It requires accelerators and activators. Accelerators are the organic chemical compound which can accelerate or slow down the vulcanisation process. Generally, addition of accelerators accelerates the vulcanisation. Activators (ZnO/Stearic acid) is also very important for Vulcanisation process.

Jul 20, 2013In doing so they react with active sites in the rubber to form crosslinks between the chains. Activators in rubber formulation are typically metal oxides (zinc oxide), and fatty acids (stearic acid). Together they form rubber soluble complexes with the accelerators making them better able to react with sulphur to develop cross-links.
