Breakthrough in High-Purity Ethyl Silicone Oil Technology Boosts Advanced Manufacturing
April 13, 2026 — Anhui IOTA Silicone Oil announced commercialization of high-purity ethyl silicone oil (CAS 63148-61-8) with 5,000-ton annual capacity. Precision ethylation control delivers exceptional thermal stability, chemical inertness, and polymer compatibility, replacing imports in automotive, textiles, and industrial coatings.
Ethyl silicone oil’s ethyl groups enhance organic compatibility vs. methyl silicone, ideal for rubber treatment, fiber lubrication, and high-temperature heat transfer. Domestic producers long lacked purity and consistency; 55% of high-end grades imported.
