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

1. properties of n-butyl stearate

n-butyl stearate is a colorless transparent liquid with an elegant odor. It is not easily soluble in water, but can be dissolved in many organic solvents, such as ethanol, ether, acetone and so on. The chemical properties of n-butyl stearate are relatively stable, and it is not easy to occur oxidation, hydrolysis and other reactions. At the same time, it also has good heat resistance, cold resistance and light resistance.

2. The use of n-butyl stearate

1. Plastic additive

n-Butyl stearate can be used as a plastic additive to improve the processing and mechanical properties of plastics. It can effectively improve the fluidity of plastics, reduce processing temperature and improve production efficiency. At the same time, n-butyl stearate can also improve the toughness and tensile strength of plastics and increase the service life of plastics.

2. Rubber softener

n-Butyl stearate can be used as a rubber softener to increase the flexibility and processability of rubber. It can reduce the hardness of rubber, improve the ductility and resilience of rubber, and make rubber products softer and more durable.

3. ink additive

n-butyl stearate can be used as an ink additive to improve the printing performance and drying performance of the ink. It can increase the fluidity of the ink and improve the printing quality and efficiency. At the same time, n-butyl stearate can also promote the oxidative drying of the ink and increase the drying speed.

4. Coating additive

n-Butyl stearate can be used as a coating additive to improve the film-forming properties and weather resistance of the coating. It can increase the fluidity of the coating and improve the flatness and gloss of the coating film. At the same time, n-butyl stearate can also improve the weather resistance of the coating and extend the service life of the coating.

In short, n-butyl stearate as an important raw material for chemical production has been widely used in plastics, rubber, inks, coatings and other fields. Understanding the properties and uses of n-butyl stearate will help to better play its role in chemical production and improve product quality and performance.
