Linear Hydroxy Silicone Oil IOTA 1203M is a high-performance organosilicon material produced by Anhui IOTA Silicones Co., Ltd. Its chemical essence is a linear polydimethylsiloxane with hydroxyl end groups.

As a colorless, transparent oily liquid, this product is available in two specifications based on viscosity and hydroxyl content: Type A with viscosity 60-70 mm²/s and hydroxyl content 1.1-2.0%; Type B with viscosity 95-105 mm²/s and hydroxyl content 0.8-0.9%. The product's moisture content is strictly controlled below 0.5%, ensuring stability and consistency.

The unique chemical structure of Linear Hydroxy Silicone Oil IOTA 1203M, represented by the formula HO[(CH3)2SiO]nH, features hydroxyl-terminated linear chains that provide special reactivity. The viscosity of hydroxy silicone oil closely relates to molecular weight, allowing precise control over polymerization degree to meet diverse application requirements.

As a key additive in silicone rubber processing, IOTA 1203M effectively controls the structuring between compound and silica, significantly improving processing performance and extending storage life. The product serves as an ideal intermediate for preparing other silicon-functional silanes, enabling the creation of various organically modified polysiloxanes through chemical reactions.

In textile finishing applications, hydroxy silicone oil can be used to prepare silicone emulsions, providing fabrics with durable softness, resilience, and water repellency. It also finds application in producing release agents for high-grade paper, demonstrating cross-industry versatility.

Linear Hydroxy Silicone Oil IOTA 1203M is packaged in 200-kilogram iron drums and must be stored in clean, dry containers in ventilated, dry warehouses. To maintain product performance, storage conditions should avoid direct sunlight and high temperatures, and prevent mixing with acidic or alkaline chemicals.

Compared with similar products, IOTA 1203M offers two options for viscosity and hydroxyl content ratio, enabling manufacturers to select the most suitable specification based on their production processes and performance requirements.

As the chemical industry moves toward refinement and functionalization, organosilicon products like IOTA 1203M that provide special modification capabilities show broad market prospects. Choosing the appropriate hydroxy silicone oil specification demonstrates unique value in improving silicone rubber processing performance and preparing special organosilicon materials.
