What is the plasticizer?
Plasticizer is a high molecular material additive. When this substance is added to the plastic material, it can make the plastic more flexible and easier to process. Plasticizers can be divided into many types according to the chemical structure, including fatty acid diesters, phthalate esters, benzoic acid esters, polyol esters polyesters, etc.
Types of plasticizers
1. Fatty acid diesters mainly include acetate ethyl and acetate butyric. This type of plasticizer is cheap and with good processability, but its weather resistance is poor.
2. Phthalate esters mainly include di(2-ethylhexyl) adipate and dibutyl phthalate. This type of plasticizer has good weather resistance and moderate price and is the most commonly used plasticizer.
3. Benzoic acid esters mainly include diethyl benzoate, dibutyl benzoate, etc. This type of plasticizer has good weather resistance and a moderate price.
4. Chlorinated hydrocarbons mainly include vicinal dichloroacetate, and this type of plasticizer has good weather resistance and moderate price as benzoic acid esters.
5. Polyesters mainly include polyester polyol polyester, polyether polyol ester, etc. The price of this plasticizer is moderate and its properties are good.
Selection of plasticizer
When selecting a plasticizer, the following factors should be considered comprehensively:
1. Plastic material and performance requirements.
2. Performance of plasticizer. Plasticizers should have good processability and weather resistance.
3. Price of plasticizer: The price of plasticizer varies greatly, and the appropriate type should be chosen according to the actual demands.
Application of plasticizer
Plasticizer is widely used in various products, such as:
1. Packing materials: plastic bags, plastic boxes.
2. Construction materials: PVC pipes, doors and windows.
3. Toys: plastic toys and rubber toys.
4. Medical devices: plastic medical devices, and rubber medical devices.
The use of plasticizers plays an important role in improving the performance of plastic products, reducing production costs, and expanding the application fields.
