It is understood that release agents have become essential industrial raw materials in industrial production, playing a very important role in mold forming and the appearance and quality of industrial products. Match different release agents for different mold materials. Our common release agents are mainly divided into the following 5 categories:
1. According to the usage of release agents, they can be divided into:There are two types of release agents: external release agent and internal release agent. The materials used for external release agent and internal release agent are different, and there is also a significant difference in price. External release agent can be directly applied to the mold, while internal release agent is a compound with a slightly lower melting point than ordinary molding temperature. During the heating and molding process, the internal release agent is added to the resin and mixed with the resin (note: compatible with liquid resin, incompatible with solid resin). Then, under certain processing temperature conditions, the internal release agent can seep out from the resin matrix, forming a thin isolation film between the mold and the product, playing a demolding effect;
2. According to the combination of release agents, they can be divided into:Composite release agents and single release agents, among which composite release agents include the combination of usage and composition, and sometimes there are significant differences in price and performance between composite and single release agents;
3. According to the usage temperature of the release agent, it can be divided into:Room temperature release agent and high-temperature release agent;
4. According to the number of times the release agent is reused, it can be divided into:Semi permanent release agents and consumable release agents are mainly distinguished based on their service life;
5. According to the performance of release agents, they can be divided into:Solvent based release agents, water-based release agents, and oil-based release agents have different chemical compositions, resulting in varying properties;
With the strong support of the country for environmental protection, no matter how many types of release agents there are, they must be based on environmental protection. Since the 1990s, the global community has attached great importance to reducing harmful steam in the working environment and canceling the use of chlorofluorocarbons (CFCs) that have a destructive effect on the ozone layer in the atmosphere.
