The function and principle of plasticizer – Chemistry Knowledge Base

Plasticizers are widely used in modern chemical production. But what exactly are plasticizers? What are their functions and principles? Many people will have questions. It plays an important role in industries such as cosmetics, plastics, rubber, and coatings. In this article, we will deeply explore the functions and principles of plasticizers, and understand different types of plasticizers.

Plasticizer, as the name suggests, is a chemical used to increase the plasticity of plastics. It can enhance the flexibility, wear resistance and cold resistance of plastics. In fact, plasticizers are often used in different types of plastics, including polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), epoxy resin (EP), etc. During the production process of these materials, adding different types of plasticizers can improve the physical properties of the product and make it more durable.

First of all, plasticizers can increase the flexibility and ductility of plastic materials, making them more flexible and wear-resistant during use. Furthermore, plasticizers can make plastics more transparent, improving quality and appearance. For materials with poor plasticity, the use of plasticizers improves production efficiency and reduces costs.

Secondly, plasticizers also have great uses in cosmetics. When cosmetics need to be more viscous, plasticizers can act as a bonding agent. At the same time, it can also adjust the moisturizing and delicate texture of cosmetics to make them more in line with people's needs.

Furthermore, the plasticizer in the coating is also crucial. Plasticizers in paint can adjust the viscosity, consistency, crack resistance, etc. of the paint, making it more suitable for use in different environments and materials. In addition, plasticizers can also increase the powder content in the coating, improve the coverage and uniformity of the coating film, and make the product look more beautiful.

Although plasticizers are widely used in industrial chemicals, there are actually some problems with the use of plasticizers. The adverse effects caused by plasticizers may threaten people's health, so you must be cautious and reasonable when using plasticizers. Therefore, when choosing plasticizers, you must choose products with excellent quality and reasonable testing and certification.

Different types of plasticizers have different principles. Among them, methyl chloride plasticizer is one of the most commonly used plasticizers at present. The use of chloromethyl ester plasticizer has the following benefits: lower toxicity, higher plasticizing effect and low cost. In addition, glycerin plasticizer also has a very good plasticizing effect, and it also has a certain effect in eliminating static electricity. Cold-resistant plasticizers and super solvent plasticizers are mainly used in environments that need to withstand extremely low temperatures. Phosphoric acid flame retardant plasticizers are mainly used in scenarios where plastics need to be prevented from catching fire. Rubber plasticizers are mainly used in the production of rubber products. Hydrogel plasticizers are mainly used to store and transport moisture-sensitive medicines, food and other commodities.

In short, the use of plasticizers has brought many benefits to modern chemical production, the key among which is to enhance the flexibility, wear resistance and cold resistance of plastics. Each plasticizer has different functions and principles, and its properties and scope of application must be understood before use. Therefore, when purchasing plasticizers, be sure to choose high-quality products and read the instructions carefully before use to avoid damaging the physical properties of the product.
