Phenyl raw silicone rubber is synthesized through precision polymerization with phenyl siloxane linkages as its core structure. The phenyl groups in its molecular chains confer unique advantages: the temperature resistance range expands to -100℃ to 350℃, maintaining elastic stability under extreme thermal cycling; the conjugation effect of benzene rings significantly enhances radiation resistance, with tensile strength retention exceeding 90% after γ-ray irradiation, outperforming conventional methyl silicone rubber; meanwhile, phenyl introduction reduces crystallization tendency, ensuring excellent flexibility at -70℃ without cracking during bending.

In aerospace, it serves as ablative-resistant sealing material for rocket engines, withstanding temperatures above 2000℃ and doubling airtightness duration. For semiconductor manufacturing, its ultra-low metal ion content (<1ppm) meets stringent chip packaging requirements, with volatile emissions below 0.01mg/m³ under vacuum. Medical-grade transparent variants achieve 92% light transmittance for intraocular lens production, passing ISO 10993 biocompatibility certification.

From deep-sea exploration equipment to nuclear power plant sealing systems, phenyl raw silicone rubber is breaking traditional application boundaries with its "extreme-resistant, ultra-pure, and high-transparency" characteristics, becoming an indispensable key material in advanced manufacturing.
