Fluorosilicone oil builds a strong protective barrier and empowers the safety upgrade of electronics and new energy

1. New energy battery thermal management adds a "Safety Guardian"
In the safety guarantee system of new energy vehicles and energy storage systems, fluorosilicone oil is becoming a key supporting material. Hydrogen-containing fluorosilicone oil, with its outstanding thermal conductivity and chemical stability, has successfully broken through the bottlenecks of traditional cooling media and achieved breakthrough applications in battery cooling systems. This type of material can maintain stable performance within a wide temperature range of -40℃ to 204℃. When operating under high load, it can quickly conduct the heat of the battery, keeping the temperature fluctuation within ±2℃, effectively delaying the decline of battery performance. Experimental data shows that the battery system applying this material has a cycle life extended by more than 30% and a safety risk reduced by 60% under extreme working conditions, providing a solid guarantee for the development of green transportation.

2. The moisture-proof and protective capabilities of electronic devices have been further upgraded
Fluorine-modified silicone oil products have demonstrated an extremely strong advantage in addressing the protection challenges of electronic devices in complex environments. Compared with traditional polyurethane and acrylic coatings, the moisture resistance of fluorosilicone oil-based moisture-proof coatings is improved by 3 to 4 times, and the water contact Angle can reach 115-119°, effectively blocking the erosion of moisture, oil stains and acidic gases. Under a high-humidity environment of 40℃ and 90%RH, its volume resistivity still maintains an excellent level of 8E-15Ω · cm, with a dielectric constant of only 2.25 (1GHz), and it causes minimal attenuation of high-frequency signals. After being applied to mobile phone base stations and automotive ECU circuit boards, the equipment failure rate dropped from 5% to 0.1%, and the maintenance cycle was extended by more than five times.

3. Structured control technology optimizes processing performance
The technological breakthrough of fluorosilicone oil in the rubber processing field has solved the structural problems that have long plagued the industry. Through the innovation of the preparation process of vinyl hydroxyl fluorosilicone oil, a structured control agent is made by polymerizing trifluoropropyl methylcyclotrisiloxane as the raw material, combined with a special capping agent and cationic catalyst at 30-60℃. This can effectively avoid problems such as hardening and increased Mooney value that occur after the mixing of fluorosilicone rubber. After adding this additive, the rubber compound can still maintain good processability after being stored for 6 months, with tensile strength increasing by 17-19 mpa. At the same time, it reduces the cost of surface treatment of silica, promoting the large-scale application of fluorosilicone rubber in the field of sealing products.

4. Multi-field standard adaptation accelerates industrial implementation
With the expansion of application scenarios, fluorosilicone oil products are gradually improving their multi-industry standard adaptation system. At present, many products have passed international standards such as UL94 non-flammability certification and JS-Z-0208 moisture permeability test. Medical-grade products have achieved a breakthrough in biocompatibility, and the metal ion content of electronic-grade products has been reduced to below 1ppm. In the aerospace field, fluorosilicone oil derivatives that can withstand temperatures up to 315℃ can resist the erosion of over 1,600 types of chemicals. In the textile field, fluorocarbon-modified silicone oil, as a defoamer and finishing agent, enhances the water and stain resistance of fabrics by 40%. The multi-standard adaptation capability is driving fluorosilicone oil from high-end laboratories to diversified industrial scenarios.
