In the extremely cold environment of -120℃, most materials have long lost their elasticity and become brittle and hard, while room temperature vulcanized phenyl silicone rubber raw rubber (IOTA 3108 series) can maintain flexible activity, becoming a material stronger in extreme environments. This special elastomer with α, ω-dihydroxy polydimethyl diphenyl siloxane as the core breaks through the performance boundary of traditional materials with molecular-level design.

Its hardcore performance comes from precise composition control: the phenyl content can be flexibly adjusted between 2.5 - 60.0 mol%, endowing the material with gradient performance from basic temperature resistance to extreme weather resistance; the wide viscosity range of 2000 - 100000 mPa·s is suitable for diversified processing needs from potting to coating. What is more rare is its stability performance - the volatile content at 150℃ high temperature for 2 hours is ≤5.0%, ensuring extremely low performance attenuation rate during long-term use, providing lasting protection for precision components.

In application scenarios, its "anti-freeze gene" shines. When spacecraft encounter sub-zero temperature of minus 100 degrees Celsius in deep space exploration, the bonding of its thermal insulation materials relies on it to maintain structural integrity; the sealing rings of polar scientific research equipment repeatedly deform in extreme cold, relying on it to maintain sealing without leakage; even in the pipeline connection parts of ultra-low temperature laboratories, it is still the key guarantee to prevent refrigerant leakage.

In addition to its low-temperature resistance talent, it also integrates multiple advantages: excellent electrical insulation makes it an ideal choice for electronic potting; radiation resistance is suitable for nuclear power radiation protection coating needs; ablation resistance and self-extinguishing make engine thermal insulation components safer. Good solubility in organic solvents such as toluene and xylene further simplifies the processing adaptation of different processes.

Practical design is also intimate: 25kg plastic bucket packaging is convenient for storage and transportation, 3-year long shelf life combined with the "qualified and reusable" characteristic reduces inventory pressure, and the safe storage requirement of keeping away from heat sources and fire sources adds more peace of mind in use. From deep space exploration to polar scientific research, this phenyl silicone rubber is safeguarding the safety of equipment in extreme environments as an "extreme cold guardian".
