Multipurpose fluorine grease

When selecting fluorine grease for molds, it is important to consider not only the heat resistance temperature but also the application locations and operating conditions. If you are experiencing issues with ejector pins or sliding parts seizing or malfunctioning, please check the following items. 【1】Operating Temperature and Load Choose a product that matches the actual temperature of the lubrication points, continuous operating time, load, and operating speed. 【2】Pin Diameter and Clearance For precision small-diameter pins, in addition to the hardness of the grease, also check the base oil viscosity and operating resistance. 【3】Gases and Gas Residues from Resins Be cautious of corrosion from gases and operational failures due to gas residues. Confirm the chemical resistance against the resin used and the gases generated, and also perform removal of residues and inspection and cleaning of venting areas. Changing the grease alone may not resolve the issue. 【4】Impact on Molded Products If you are concerned about oil separation or grease adhesion, review the product characteristics and the application position and amount. 【5】Cleaning and Greasing Conditions Consider the greasing intervals, and when switching products, remove and clean the old grease according to the product instructions. Make sure to inspect for scratches and wear on the parts before making a selection. When consulting, please provide information on the application location, temperature, resin used, and current symptoms.

Are you troubled by mold burning, wear, or grease bleeding? Selecting mold grease that matches the usage temperature, sliding conditions, and operating environment is important. At M&M Co., Ltd., we offer a variety of greases tailored to different applications, from high-temperature greases for die-casting molds to fluorine greases, general mold greases, food container mold greases, and greases for O-rings and gaskets. We have prepared an introductory document that allows you to compare mold greases by application and temperature. If you are unsure which grease to choose, want to review the grease you are currently using, or need to address high temperatures, burning, or bleeding issues, we can provide recommendations based on your usage conditions. Please feel free to contact us if you are having trouble with mold maintenance or grease selection.

Fluorine grease and silicone grease are both lubricants with excellent heat resistance and chemical resistance, but there are clear differences in their applications and performance. Fluorine grease is primarily composed of PFPE (fluorinated oil) and PTFE, characterized by its excellent stability in high-temperature and chemical environments. For example, it maintains stable performance over a wide temperature range of -25°C to 280°C and is less affected by chemicals and solvents, making it suitable for lubricating sliding parts of molds and precision components. On the other hand, silicone grease is based on silicone oil and is characterized by its low tendency to damage rubber and resin, as well as its excellent waterproofing and insulation properties. Therefore, it is suitable for areas where material protection is important, such as O-rings, gaskets, and waterproof applications. In summary: - High temperature, chemical resistance, long lifespan → Fluorine grease - Waterproof, rubber protection, insulation → Silicone grease It is important to differentiate between them based on their uses. Selecting the appropriate lubricant according to the usage environment leads to trouble prevention and improved maintenance efficiency.

Fluorine grease is used in a wide range of fields such as semiconductor equipment, chemical facilities, and food machinery as a high-performance lubricant with excellent heat resistance and chemical resistance. Its ability to maintain stable lubrication performance even in high-temperature environments and chemical contact environments is particularly noteworthy. On the other hand, there are also disadvantages. First, the high cost of raw materials tends to make the price expensive. Additionally, while it excels in low friction, its extreme pressure performance is not high, which may make it unsuitable for high-load applications such as large gears and heavy machinery. Furthermore, in general environments, its performance may be excessive, leading to cost disadvantages. Lubricants are not simply "high performance = optimal"; selecting the right one according to the usage environment is crucial. When chemical resistance and high-temperature compatibility are required, fluorine grease is appropriate, while for high loads, molybdenum grease may be needed, necessitating a distinction based on the application.
