In the wave of modern industrial and technological development, materials science has always played a crucial role. As application environments become increasingly challenging and extreme, traditional materials often fail to meet the demands. IOTA Silicone Oil(Anhui) Co., Ltd., a pioneer in the organosilicon industry, is bringing revolutionary breakthroughs to fields such as aerospace, new energy, and electronics with its phenyl silicone rubber products, thanks to their exceptional low-temperature resistance.

Scientific Decoding: The Extraordinary Cold Resistance Provided by the Phenyl Structure
The reason phenyl silicone rubber maintains excellent performance in extreme low-temperature environments stems from its unique molecular structure. When phenyl groups are introduced into the siloxane main chain, this large-volume group effectively disrupts the regularity of the molecular structure, significantly lowering the crystallization temperature and glass transition temperature of the polymer. It is this molecular-level innovative design that allows IOTA's phenyl silicone rubber to maintain elasticity and functionality even in extremely cold environments of -110℃, far exceeding the -60℃ cold resistance limit of ordinary silicone rubber.

The Technical Director of IOTA Silicone Oil(Anhui) Co., Ltd. stated: "Precise control of phenyl content is the core of our technology. By adjusting the phenyl content, we can customize product performance for different application scenarios – low phenyl content ensures fluidity at ultra-low temperatures, preventing material embrittlement; while high phenyl content provides excellent radiation and high-temperature resistance."

Cutting-Edge Applications: From Space Exploration to Emerging Technologies
Aerospace Field
In the critical sealing systems of spacecraft, materials must withstand extreme temperature variations in space. IOTA's phenyl silicone rubber seals, tubing, and gaskets play an irreplaceable role in major projects such as the Russian Soyuz spacecraft and the Chinese Tiangong space station. These components not only maintain sealing performance in the deep space environment of -110℃ but also resist cosmic ray radiation, ensuring the safety of space missions.

New Energy Technology
With the rapid development of the new energy vehicle industry, the requirements for materials in battery thermal management systems are becoming increasingly stringent. IOTA's phenyl silicone rubber is used for sealing and cushioning between battery modules, maintaining excellent elasticity and sealing performance even in winter environments of -40℃ in cold regions, effectively preventing thermal runaway risks. Furthermore, its application in AI server cooling systems is rapidly expanding, providing assurance for the stable operation of data centers under extreme climate conditions. Cutting-Edge Electronic Technology
High-end electronic devices such as 5G base stations and quantum computers present new challenges for insulating materials. Iota phenyl silicone rubber, with its stable electrical insulation performance at ultra-low temperatures, has become the material of choice for electronic equipment in special environments such as polar scientific research stations and high-altitude meteorological monitoring stations. A technical report from a major international telecommunications company shows that the failure rate of polar communication equipment packaged with phenyl silicone rubber has decreased by 67%.

Market Insight: Surging Demand and Industrial Upgrading
With global warming leading to frequent extreme weather events, and the rapid development of deep-sea exploration, polar scientific research, and aerospace exploration, the market for low-temperature resistant materials is experiencing explosive growth. According to industry analysis data, the global high-end phenyl silicone market size exceeded US$3 billion in 2025, with a compound annual growth rate of 12.5%. However, the production technology of high-end phenyl silicone rubber has long been monopolized by a few international chemical giants, and the domestic market self-sufficiency rate is less than 30%.

IOTA Silicone Oil(Anhui) Co., Ltd., through close cooperation with several universities and research institutions in Nanjing, has successfully broken through key technological barriers and achieved large-scale production of high-purity phenyl silicone rubber. The company's products have passed ISO9001 quality management system certification, and some product performance indicators even exceed those of similar international products, providing important support for the independent development of my country's high-end equipment manufacturing industry.

Future Outlook: Technological Innovation Drives Sustainable Development
Looking ahead, Iota will continue to deepen technological innovation in phenyl silicone rubber. It is understood that the company is developing a new type of phenyl silicone rubber with an ultra-low glass transition temperature, which is expected to further push the low-temperature resistance limit to -135°C, providing material support for deep space exploration missions such as lunar south pole research stations and Mars probes.

At the same time, the company actively responds to the national "dual carbon" strategy, developing green production processes to reduce energy consumption and emissions in the production of phenyl silicone rubber. The General Manager of IOTA Company stated: "We not only pursue excellence in product performance, but also prioritize environmental friendliness throughout the entire product lifecycle.  Over the next three years, we will invest 50 million yuan in upgrading our environmentally friendly processes, striving to reduce carbon emissions per unit of product by 40%."

Conclusion
From polar ice fields to vast outer space, from deep-sea exploration to quantum computing, IOTA phenyl silicone rubber is providing solid support for humanity's exploration of the unknown and pushing the boundaries of possibility with its excellent low-temperature resistance.
