As aerospace equipment, precision instruments, cold chain equipment, high-end electronics, and new energy industrial control equipment continuously expand into extreme environment scenarios, the market has imposed strict requirements on lubricating, insulating, damping, and shock-absorbing oils. Ordinary mineral oils and conventional silicone oils are prone to solidify and have their viscosities sharply increase in low-temperature environments, losing their operational efficiency; general phenolic silicone oils have a clear upper limit in their ability to withstand low temperatures and are difficult to meet the requirements for continuous operation at extremely low temperatures. Product 255C, a modified phenolic silicone oil with low-temperature resistance, has achieved stable mass production. Based on the high phenolic molecular structure design, it has far superior low-temperature flow properties to conventional phenolic silicone oils, and a wide working temperature range that is suitable for alternating high and low temperatures. It provides a new option for organic silicon solutions for extreme environment applications.
Product 255C, a modified phenolic silicone oil with low-temperature resistance, belongs to high phenolic content modified phenolic silicone oil. Its appearance is colorless or light yellow transparent liquid, and its core physical and chemical indicators have a wide adjustable range. The 25°C kinematic viscosity ranges from 50 to 1000 cst, and it can be customized to the corresponding viscosity specification according to customer requirements; the 25°C relative density is controlled within 1.00 to 1.02, and the refractive index is within the range of 1.4100 to 1.440; the open cup flash point is ≥ 280°C, with outstanding high-temperature safety; the freezing point is low to ≤ -120°C, and it still maintains good fluidity in extremely low-temperature environments. The theoretical applicable temperature range can reach -120°C to 280°C, and the long-term stable working range covers -110°C to 250°C, effectively addressing the pain points of many fluid materials such as "low-temperature freezing and high-temperature deterioration".
Compared to ordinary phenolic silicone oil, the core advantage of product 255C lies in its balanced wide temperature range performance. The material has excellent low-temperature fluidity, long-term antioxidant capacity, good lubrication characteristics, and outstanding radiation resistance and hydrophobic stability. In low-temperature environments, it will not rapidly thicken and solidify, ensuring the normal operation of lubrication and damping functions during the equipment startup stage; in continuous high-temperature conditions, it is not prone to volatilization, cracking, or carbon deposition, and has excellent thermal stability. The combination of multiple characteristics makes this modified phenolic silicone oil multifunctional, and it can be widely used as an insulating medium, lubricating medium, damping fluid, and shock-absorbing filler fluid, meeting the requirements of precision equipment in multiple industries.
In the field of precision instruments, a large number of sensors, dampers, and shock-absorbing components have long been facing alternating high and low temperature environments. Ordinary damping oils have a sudden change in viscosity when the temperature drops, causing imbalance in damping force and measurement accuracy deviation. Using product 255C as a damping fluid can maintain stable viscosity in extremely cold environments, ensuring consistent damping and shock-absorption performance of the instruments. Internal transmission components of aerospace, outdoor exploration equipment, and polar monitoring equipment can rely on this product for long-term lubrication, avoiding low-temperature startup jamming faults. At the same time, the product has excellent insulation properties and is suitable for some low-temperature conditions for insulation impregnation and heat protection of electronic components.
New energy, industrial control outdoor equipment, and cold chain supporting machinery also have broad application spaces. Many outdoor equipment encounter extreme cold weather in winter, and the failure of lubricating media will directly cause equipment shutdown. Product 255C, a modified phenolic silicone oil with low-temperature resistance, has stable chemical properties and does not react with metals or plastic substrates, is suitable for various sealing structures, and reduces the probability of component wear. Additionally, its excellent radiation resistance can also meet the material tolerance requirements for some special conditions.
In terms of packaging and storage, product 255C, a modified phenolic silicone oil with low-temperature resistance, provides 25-kilogram, 50-kilogram plastic drums, and 200-kilogram iron drums in various packaging specifications, catering to both small-batch samples and large-scale enterprise bulk purchases. The product needs to be stored in clean, dry, and sealed containers and placed in a ventilated and dry warehouse; it should be stored as non-dangerous goods and does not require complex hazardous material logistics procedures, effectively reducing enterprise logistics and storage management costs. Under standard storage conditions, the product's shelf life can reach 3 years, and the raw material turnover and inventory planning become more flexible.
At present, the domesticization of high-end equipment is continuously advancing, and the demand for special fluid materials for extreme working conditions is continuously increasing. In the past, many ultra-low temperature scenarios used wide temperature range phenyl silicone oil, which was long dependent on imports. The supply cycle was long and the procurement cost was high. The product 255C low-temperature resistant modified phenyl silicone oil has indicators对标ing international similar products, stable supply, and helps domestic equipment manufacturing enterprises achieve raw material domestic substitution.
From the industry development trend, the equipment usage environment is becoming increasingly complex, and lubrication and damping materials applicable to a single temperature range gradually fail to meet market demand. The wide temperature range organic silicone fluid with multiple functions such as low-temperature resistance, high-temperature resistance, oxidation resistance, and insulation lubrication has greater development opportunities. The product 255C low-temperature resistant modified phenyl silicone oil, with an extremely wide usage temperature window and diversified functional positioning, covers multiple tracks such as precision instruments, detection equipment， outdoor industrial control， and aviation support， providing reliable material choices for formulation engineers and equipment R&D personnel， and continuously promoting the high-quality development of specialized organic silicone material industries for extreme working conditions.
