According to the "China Release Agent Market Research and Development Prospects Research Report (2016 Edition)", the release agent is a functional substance between the mold and the finished product, which is to prevent rubber, plastic and other elastomers and other materials. The molded article is bonded to the surface of the mold to provide a type of processing aid for easy release.
China is a big country in the production and consumption of plastics and rubber. Since the beginning of the 21st century, the plastics and rubber industry has maintained a high rate of growth. The production capacity of plastic products has exceeded 20 million, surpassing Japan to rank second in the world. Production and consumption exceeded 3 million tons, ranking first in the world. With the vigorous development of the rubber and plastics industry, the use of release agents has become more widespread, and the amount of release agents has also increased significantly, especially in the past few decades, injection molding, extrusion, calendering, molding, lamination and other processes. The rapid development has promoted the development of release agents. In terms of output and variety, mold release agents have become a major category of rubber and plastics additives.
There are many kinds of release agents, and the price and performance are very different. Due to the lack of scientific quantitative measurement methods and data, and the reasons for technical secrecy, the preparation methods and application status of release agents are less reported in the literature. Test and evaluation methods, different companies and manufacturers have different standards. The release mechanism and selection principle of the release agent introduces a preparation method of the fluorine-containing release agent. Among the many types of release agents, fluorine and silicone release agents are two types of release agents which have been developed rapidly in recent years because of their good release effect and suitable mold release.
