Single pressed stearic acid is widely used in rubber, plastic, paper making, textile, food , cosmetic, detergent and metal salts industries, etc.
plasticized with 5% or 7% stearic acid and 3% or 5% glycerol. The addition of 7% glycerol or 3% stearic acid make increase both tensile strength and elongation at break.
Commonly used plasticizer are: butyl phthalate(DBP), phthalate dioctyl(DOP), sebacic acid dioctyl ester（DOS), etc. 3.2.4 Uv stabilizer In outdoor use of polymer materials, caused by the photodegradation of light cannot be ignored.
The compound formulation by weight was PVC (100), plasticizer (50), calcium/zinc stabilizer (2.5), and stearic acid (0.25). In Study 3, like Study 2, the level of plasticizer was held constant. 3 The ingredients were mixed in a planetary mixer and then placed on a two-roll mill for 10 minutes at 163°166°C.
Stearic acid is a saturated fatty acid with an 18-carbon chain and has the IUPAC name octadecanoic acid. It is a waxy solid and its chemical formula is C17H35CO2H. 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 one of the most common saturated fatty acids found in nature following palmitic acid. The triglyceride derived from three molecules of stearic acid is called stearin.

Edible barrier films complement modified atmosphere in preserving food quality and extending shelf life. The effects of plasticizer (stearic acid or propylene glycol), pH (4.4 or 9.4) and degree ...
The gelatinization enthalpies of the starch in the extruded films varied from 0 to 1.7 J/g, and were dependent largely on the extrusion temperature and plasticizer content. The shift in the FTIR spectral bands, as well as the appearance of double-peaks, suggested strong hydrogen bonding interactions between the starch and plasticizers.
