In addition-cured silicone systems, the structure and purity of the crosslinker directly affect curing efficiency and final performance. End-functional hydrogen-containing phenyl silicone oil IOTA-234 (Chemical Name: 3,5-Bis(dimethylsiloxy)-1,1,7,7-tetramethyl-3,5-diphenyltetrasiloxane, CAS: 66817-59-2) is a high-purity, low-molecular-weight hydrogen-containing phenyl siloxane. Thanks to its we

As a key active component of addition-cured phenyl silicone rubber, Phenyl Vinyl Silicone Oil IOTA-252 (Di-vinyl-terminated Phenyl Methylsiloxane, CAS: 225927-21-9) offers well-defined structure, controllable reactivity, and batch-to-batch consistency, and has been reliably used for years in high-temperature, radiation-resistant, and high-insulation silicone rubber applications. IOTA-252

With the increasing demand for extreme-environment resistance, electrical insulation, and flexibility in advanced composite materials, epoxy phenyl silicone oil (IOTA Series) has emerged as a reactive organosilicone modifier for upgrading epoxy, polyurethane, and polycarbonate systems. This solvent-free product is a diglycidyl-terminated phenyl trisiloxane, with typical specifications as

In the production of high-performance silicone rubber products, processing stability and batch-to-batch consistency are critical. As a key processing additive, hydroxyl-terminated phenyl methylsiloxane–dimethylsiloxane copolymers (IOTA Series structural control agents) have played an irreplaceable role for many years in silicone rubber compounding, extrusion, and molding processes, thanks to th

As a top-selling phenyl silicone oil product in China, the IOTA-255 series from IOTA has been widely applied in high-temperature lubrication, electrical insulation, and special damping fields, gradually replacing some imported counterparts, thanks to its wide temperature adaptability, excellent comprehensive performance, and more competitive cost.

As a mature and stable polymethylphenylsiloxane product, the low-viscosity methylphenyl silicone oil IOTA 250-30 has maintained reliable application in fields with high requirements for material stability such as power electronics, instrumentation and temperature control systems for many years, relying on its low viscosity, low pour point and excellent electrical properties.

In the scientific research and industrial fields with extremely strict requirements for vacuum environments, the ultra-high vacuum (UHV) diffusion pump oil IOTA705 (domestic grade 275) has stably served key equipment such as electron microscopes, high-vacuum coating equipment, accelerators and special light sources for many years, relying on its extremely low saturated vapor pressure a
