Mold Universal Fluorine Grease

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 a high-performance lubricant that excels in heat resistance, chemical resistance, and low outgassing. It is used in environments where conventional mineral oil greases are inadequate. The main applications are as follows: - Mold components in high-temperature environments (approximately 200°C or higher) such as ejector pins and slides - Equipment parts exposed to chemicals or solvents - Clean environments (semiconductors, food, medical devices) - Areas requiring contamination control in resin molding Fluorine grease is chemically stable and has a characteristic that makes it difficult to mix with other greases. Therefore, degreasing and cleaning before application are crucial. Additionally, while it has excellent heat resistance, its extreme pressure performance is limited, which means it may not be suitable for areas subjected to high loads or shock loads. Proper selection according to the application directly contributes to preventing mold troubles and improving maintenance.

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.

In high-temperature environments, grease does not simply diminish; its "state" deteriorates due to hardening, separation, and carbonization. Even if there is some remaining, the lubrication function decreases, leading to increased sliding resistance, poor return, and fine seizure. If these warning signs are ignored, it will eventually progress to seizing or burning. Therefore, the idea that "using high-performance grease eliminates the need for reapplication" does not hold true in high-temperature areas. What is important is to visualize the signs of abnormalities and to establish rules for inspection, cleaning, and reapplication. Especially in die-casting molds, temperature changes, high surface pressure, and dust contamination overlap, causing lubrication conditions to fluctuate constantly. Maintaining a stable operational state takes precedence over reducing maintenance frequency. 【High-Temperature Sliding Component Checklist】 □ Is the return of the pin sluggish? □ Are there any signs of seizure or dust accumulation? □ Is the grease hardened or film-formed? □ Is there any catching when starting to move? □ After cleaning, is the appropriate amount reapplied? Rather than forcibly reducing maintenance frequency, the realistic approach is to operate in a way that prevents stoppage accidents before they occur.
