Butyl stearate is an important chemical raw material, widely used in plastics, rubber, coatings, cosmetics and other fields. This article will detail the properties and uses of butyl stearate.

1. Properties of Butyl Stearate

Butyl Stearate is a colorless or yellowish transparent oily liquid with an elegant odor. Its molecular formula is C22H42O2 and its molecular weight is 338.57. Butyl stearate is insoluble in water, but it is miscible with most organic solvents, such as ethanol, ether, benzene, etc. In addition, it also has the following properties:

1. Thermal stability: Butyl stearate has good thermal stability, can be used at higher temperatures, and is not easy to decompose and deteriorate.

2. Cold resistance: Butyl stearate has a lower freezing point, can be used at low temperatures, and is not easy to solidify.

3. Oxidation resistance: Butyl stearate has good oxidation resistance and can be stored in the air for a long time without being oxidized and deteriorated.

stearate as an important chemical raw material, in various fields have a wide range of applications, the following mainly introduces its use in plastics, rubber, coatings and cosmetics and other fields.

1.

in the field of plastics Butyl stearate can be used as a plasticizer and lubricant in the process of plastic processing, which can improve the processing performance and use performance of plastics. It can be used in plastics such as polyvinyl chloride, polyethylene, and polypropylene to make it softer and smoother, and to improve its toughness and ductility.

2.

in the field of rubber Butyl stearate can be used as a softener and plasticizer for rubber, which can improve the processability and use performance of rubber. It can be used in natural rubber, synthetic rubber and other rubber products to improve its softness, elasticity and cold resistance.

3.

in the field of coatings Butyl stearate can be used as a solvent and plasticizer for coatings, which can improve the construction performance and use performance of coatings. It can be used in different types of coatings such as oil-based coatings and water-based coatings to improve the leveling, gloss and adhesion of the coatings.

4.

in the field of cosmetics Butyl stearate can be used as the base material and emollient of cosmetics, which can improve the texture and feel of cosmetics. It can be used in cosmetics such as skin cream, lotion and lipstick to improve its extensibility, lubricity and moisturizing properties.

In short, butyl stearate, as an important raw material for the production of chemical products, is widely used in various fields and provides important help for the production and processing of products.
