Product Description

[ Stearic acid ]

Application

1. It can be used as a vulcanizing active agent for natural rubber, synthetic rubber and latex.
2. Used in medicine to prepare ointment, suppository, etc.
3. In the electronic ceramic hot die casting molding process, it can improve the slurry viscosity and prevent the bad body wax cracking.
4. It can be used as a plasticizer and stabilizer in plastics
5. It can be used as release agent for electronic components in electronic products.

Stearic acid is one of the main long-chain fatty acids that make up oils and fats. It exists in animal fats, oils and some vegetable oils in the form of glycerides. Stearic acid is obtained by hydrolysis of these oils. Stearic acid is a kind of fatty acid widely existing in nature. It has the chemical properties of general carboxylic acid. Almost all oils contain stearic acid with different content. The content of stearic acid in animal fat is higher, such as 24% in butter, less in vegetable oil, 0.8% in tea oil and 6% in palm oil, but the content in cocoa butter is higher. Up to 34%.

The difference between the type classification of stearic acid, such as SA1801 and 1838.1825, etc., is as follows:

1.Different nature

18 mainly refers to C18 stearic acid in stearic acid, which is an important indicator of stearic acid.

General industrial palm oil direct hydrogenation - hydrolysis of stearic acid, C18 content is usually 38-42%, through fractionation, can get higher C18 content of stearic acid, while producing low C18 content of stearic acid (mainly C16), C18 content is usually higher, the higher the price, while the high C16 price is low. Of course high purity (> Except for 98%).
 

2.Different quality indicators

1830, 1831, 1838, 1839 and other models are different manufacturers' labels, 18** series may be mainly foreign and imported brands, mainly to distinguish C18 content, but different manufacturers' models may be the same, but its quality indicators are not necessarily the same.
 

3.Different levels

Primary acids such as 1838 and 1840. 1801 and 1810 are tertiary acids.

4.Different categories

1838 and 1840 mainly used plant raw materials, also known as plant acids. 1801, 1810 is an animal raw material, generally known as animal acid.
