| 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. 6. It can also be used in the manufacture of cosmetics, candles, waterproofing agents, polish agents, etc |

| 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. |
