Krytox VPF 1525 PFPE grease for Semiconductors and Aerospace

1. Description

Krytox VPF 1525 features extremely high chemical stability and oxidation resistance, and is mainly applied in vacuum systems, oxygen environments, high-cleanliness equipment, and chemical corrosion conditions.

3. Main Features

(1).Ultra-low volatility

VPF 1525, after precise distillation treatment, has an extremely low vapor pressure, which can significantly reduce oil return and contamination problems in vacuum systems and is highly suitable for high vacuum equipment.

(2). Excellent high-temperature resistance

PFPE material still has extremely strong stability at high temperatures, is not prone to carbonization or oxidation, and can work for a long time in high-temperature environments.

(3). It is extremely chemically inert

It has extremely strong resistance to most chemical media, acids and alkalis, oxygen and corrosive gases, and will not react with plastics, rubber and metals.

(4). Non-flammable and suitable for oxygen systems

Traditional mineral oil poses a risk of combustion in an oxygen-rich environment, while Krytox VPF 1525 is a non-flammable lubricating oil and can be safely used in oxygen compression systems and oxygen pumps.

(5). Long-life lubrication

Because PFPE oil is not prone to oxidation, its service life is much longer than that of ordinary lubricating oil, which can reduce maintenance frequency and equipment downtime.

4. Application

(1).Vacuum pump system

Widely used in: molecular pumps, rotary vane vacuum pumps, diffusion pumps, semiconductor vacuum equipment, coating equipment, especially suitable for working conditions with high vacuum and high cleanliness requirements.

(2). Semiconductor and electronics industry

Due to its low volatility and low pollution characteristics, it can be used in: wafer manufacturing equipment, photolithography equipment, vacuum chambers, semiconductor conveying systems, and can reduce the pollution of precision electronic components by oil and gas volatilization.

(3). Oxygen and Chemical equipment

VPF 1525 has extremely high safety in oxygen environments and can be used in: oxygen compressors, oxygen pumps, chemical reaction equipment, and strongly corrosive gas environments

(4). Aerospace equipment

PFPE lubricants can still work stably in high vacuum, extreme temperature and harsh chemical environments, and are therefore often used in aerospace vacuum systems and special bearing lubrication.

(5). Food and pharmaceutical equipment

Due to its NSF H1 food-grade certification, it can be applied to: food vacuum packaging equipment, pharmaceutical vacuum systems, and clean production lines.

In a word, Krytox VPF 1525 features ultra-low volatility, excellent chemical inertness and extremely strong high-temperature stability, and is widely used in the semiconductor, aerospace, chemical and vacuum pump industries.
