The versatility of direct zinc oxide makes it an indispensable additive in the plastics industry for the following main reasons:
1. Improving the heat resistance of plastics
Direct zinc oxide can be added to plastics to improve the heat resistance of plastics by stabilizing the molecular chain. Under high temperature conditions, direct zinc oxide can prevent the breakage of plastic molecular chains and reduce chemical reactions between molecules, thereby effectively protecting the performance of plastics and enabling them to maintain stable physical and chemical properties under high temperature conditions.
2. Enhanced light stability
Direct zinc oxide also has excellent light stability and can be used as a UV absorber to convert ultraviolet (UV) energy into harmless heat energy to prevent UV radiation from damaging plastics. UV radiation can break the molecular chains of plastics, causing them to become brittle and age, and the addition of direct zinc oxide can significantly extend the service life of plastics and maintain their stable appearance and performance.
3. Improved flame retardancy
Direct zinc oxide can also be used as a flame retardant in plastics to improve the flame retardancy of plastics by reducing pyrolysis products and slowing down the burning rate. In plastic products in the electronics industry and construction industry, direct zinc oxide has a wide range of applications as a flame retardant, which can effectively reduce the risk of fire and protect people's lives and property.
4. Promote curing and processing process
Direct zinc oxide also plays an important role in the processing of plastics. It can be combined with some curing agents to form a cross-linked structure, thereby enhancing the physical properties of plastics. In addition, direct zinc oxide can also improve the fluidity of plastics, shorten the molding cycle, and improve the quality of finished products. This makes the plastic processing process more efficient and reduces production costs.
5. Wide applicability
Direct zinc oxide is not only suitable for many types of plastics, such as polyethylene, polypropylene, polyvinyl chloride, etc., but also for different processing methods, such as injection molding, extrusion, blow molding, etc. This wide applicability makes the application of direct zinc oxide in the plastics industry more flexible and diverse.
6. Environmental protection
Direct zinc oxide is a non-toxic substance that does not cause harm to the human body and the environment. Today, with the increasing awareness of environmental protection, the environmental protection of direct zinc oxide has made it widely used in many fields, including the plastics industry. Using direct zinc oxide as an additive helps reduce the impact of plastic products on the environment during production and use.
Direct zinc oxide's versatility, improved heat resistance of plastics, enhanced light stability, improved flame retardant properties, accelerated curing and processing, wide applicability and environmental friendliness make it an indispensable additive in the plastics industry.
