塑膠在製造過程中，常需添加劑以提升其性能和品質。這些添加劑通常被稱為助劑，其功能包括增加塑膠的柔軟度、耐熱性、耐候性和耐化學性等。透過使用不同的添加劑，製造商可以調整塑膠的特性，以符合不同的應用需求。
使用合適的添加劑可以改善塑膠的加工性能，使其更易於製造和加工。例如，在注塑成型過程中，添加劑可以幫助塑膠材料更好地流動，從而獲得更精確的成型產品。此外，一些特殊功能的添加劑還可以提供抗紫外線、防火等特殊功能，擴大了塑膠在各個領域的應用範圍。
然而，選擇合適的添加劑並非易事，因為添加劑的種類繁多，每種添加劑都有其獨特的功用和特性。製造商需要仔細研究助劑的功能和應用，確保所選擇的添加劑能夠達到預期的效果並滿足市場需求。
在助劑品質方面，製造商應該選擇具有良好品質和穩定性的添加劑，以確保產品的一致性和穩定性。此外，添加劑的安全性和環保性也是製造商需考慮的關鍵因素，應盡量選擇符合相關標準和法規的助劑產品。
在整個助劑市場中，化學劑和工業添加劑是最常見的助劑類型，其應用範圍廣泛，並對工業生產起著至關重要的作用。各種添加劑的批發業務也相應興盛，為製造商提供了更多選擇和便利。

Title: The functions of additives in plastic production
Article: In the manufacturing process of plastics, additives are often required to enhance their performance and quality. These additives, commonly known as auxiliaries, serve functions such as increasing the flexibility, heat resistance, weather resistance, and chemical resistance of plastics. By using different additives, manufacturers can adjust the properties of plastics to meet various application needs.
The use of suitable additives can improve the processing performance of plastics, making them easier to manufacture and process. For example, in the injection molding process, additives can help plastic materials flow better, resulting in more precise molded products. In addition, some special function additives can provide special features such as UV resistance, flame retardancy, and more, expanding the application range of plastics in various fields.
However, selecting the right additives is not an easy task, as there are various types of additives, each with their unique functions and characteristics. Manufacturers need to carefully study the functions and applications of additives to ensure that the selected additives can achieve the expected effects and meet market demands.
In terms of the quality of additives, manufacturers should choose additives with good quality and stability to ensure product consistency and stability. Additionally, the safety and environmental friendliness of additives are also key factors that manufacturers need to consider, and they should choose additive products that conform to relevant standards and regulations.
In the entire additive market, chemical agents and industrial additives are the most common types of additives, with a wide range of applications that play a crucial role in industrial production. Wholesale business of various additives is also flourishing, providing manufacturers with more choices and convenience.
