Additives are chemical substances or processes used in material preparation to improve the properties or processing characteristics of materials, such as plasticizers, auxiliaries, and fillers. Their core functions include: 1. Enhancing material properties (e.g., heat resistance exceeding 300℃, abrasion resistance increased by 50%-70%); 2. Optimizing processing technology (reducing energy consumption by 20%-30%, improving flowability and dispersibility); 3. Extending service life (slowing down aging rate through antioxidants, extending service life by 2-3 times). Typical applications include toughening plastic products (increasing flexural modulus by 80%) and corrosion protection of coatings (salt spray resistance exceeding 1000 hours).
1. Improving Material Properties
Additives can improve the physical, chemical, and mechanical properties of materials, such as heat resistance, toughness, abrasion resistance, and corrosion resistance. Additives can give materials superior performance, increase their service life, and reduce usage costs.
2. Improving Material Processing Performance
Additives can make the moisture content of materials more suitable, making them easier to prepare and process. Under high-temperature conditions, additives can prevent problems such as poor material flow and difficulty in extrusion, thus improving processing efficiency. Furthermore, additives can improve material dispersibility and reduce energy consumption during the preparation process.
3. Extending Material Lifespan
Additives can increase the durability and cellular stability of materials by altering their structure. They can also slow down the aging process and enhance antioxidant properties, thereby extending the material's lifespan.
