1. Basic knowledge of plastics
Plastic is a polymer compound made of synthetic resin and a variety of additives (such as fillers, plasticizers, stabilizers, fluorescent whitening agents and colorants, etc.). The basic structure of plastic is polymer chain , usually composed of repeating monomers. Through polymerization reactions (such as addition polymerization, condensation polymerization), these monomers form long-chain structures that give plastics unique physical and chemical properties. 2. Commonly used Plastic classification
3. Applicability of commonly used fluorescent whitening agents in plastics of different materials
Fluorescent whitening agent also known as optical brightener , is a chemical product that can absorb ultraviolet rays and reflect blue-violet light visible to the naked eye. It can significantly improve the whiteness, brightness and weather resistance of plastic products. Through the correct use of optical brighteners, plastic manufacturers can produce high-quality plastic products that meet market demand. Different types of fluorescent whitening agents are suitable for different plastic materials. When selecting optical brighteners, you should follow the technical guidance of the application engineer to ensure that the correct type of optical brightener and the appropriate addition amount are used. Hongyi Chemical provides application technical services to each customer based on the requirements of customers in different industries. For more questions about optical brighteners, you can call 0578-7213888 and Hongyi engineers will serve you wholeheartedly!
