With increasing demands in polar resource development and deep-space exploration, materials capable of maintaining elasticity below -90°C are vital. Hydroxyphenyl silicone rubber, with its superior low-temperature flexibility and crosslinking capability, is emerging as a top choice for cryogenic sealing and encapsulation.

Modified from conventional methyl silicone rubber with phenyl side chains and terminal hydroxyl groups, this material exhibits excellent extension at low temperatures and strong reactivity for high-performance gels and elastomers. It is widely used in polar communication systems, space probe components, and cold-chain automation.

Its optical and dielectric stability, along with tunable transparency and hardness, make it reliable in demanding, multi-functional applications requiring high performance under extreme cold.
