P-BBARRIERTA L 25 DL PFPE Grease Low Friction Sensitive Materials

- Model: P-BBARRIERTA L 25 DL
- Packaging: 1KG
- Key Ingredients: Perfluoropolyether, polytetrafluoroethylene, and additives.

- Type: Perfluoropolyether PTFE sensitive materials grease, low friction plastic plastic lubricant, EPDM silicone rubber compatible grease, low volatility railway door sealing grease. P-BBARRIERTA L 25 DL is a specialized perfluoropolyether-based (PFPE) lubricant optimized for sensitive materials. It is designed to provide long-lasting lubrication solutions with a wide temperature range, low friction, and compatibility with sensitive materials, specifically for multi-material friction pairs such as plastic/plastic and elastomer/metal.

- Compatibility with Sensitive Materials: Undergone extensive material compatibility testing, demonstrating excellent suitability with sensitive plastics and elastomers such as PC (polycarbonate), EPDM (ethylene-propylene-diene monomer), and silicone rubber. It does not cause swelling, hardening, or embrittlement, addressing the issue of traditional lubricants damaging precision materials. Specifically, in railway seal applications, it maintains the long-term flexibility of rubber strips and slows down UV-induced aging.
- Wide Temperature and Low Friction Characteristics: Leveraging the synergy between PFPE and PTFE, it maintains low starting torque even in low-temperature environments as extreme as -25°C, ensuring smooth operation of components such as train doors and electronic device motors. In plastic/plastic friction pairs, the coefficient of friction can be as low as 0.08-0.11, with minimal fluctuation across temperature changes, ensuring long-term stability in controlling operational resistance.
- Resistance to Multiple Media and Low Volatility: It exhibits excellent resistance to water, hydrocarbon solvents, industrial steam, and weak acid/alkali media, with the lubrication film resistant to degradation. Its volatility is far below industry standards, making it suitable for long-term operational components such as cooling fan bearings in electronic devices and pump bearings in chemical applications, reducing lubricant loss and carbon buildup, thereby lowering maintenance frequency.

Given its material compatibility and wide temperature characteristics, P-BBARRIERTA L 25 DL is focused on lubrication for sensitive materials and diverse operating conditions. In the railway sector, it serves as a core lubrication solution for train door sealing rubber strips, forming an ultra-thin lubrication film (50% thinner than traditional products), preventing clothing adhesion while ensuring stable door operation under tunnel pressure variations. In the electronics industry, it is suitable for hard disk motor bearings and cooling fan shafts, with low volatility protecting circuit boards and optical components from contamination. In the chemical and mechanical sectors, it is used in pump bearings with EPDM seals and PC material guide rails, balancing resistance to media corrosion and material protection. Additionally, it can be applied to small transmission components in automotive electronic systems, compatible with combinations of plastic and rubber materials.
