The IOTA 2030 series is a linear polysiloxane modified with primary hydroxyl groups at both ends. It can be used as an active component in polymerization reactions for the synthesis of silicone-polyurethane and silicone-polyester block copolymers, imparting improved low-temperature flexibility, processability, anti-blocking properties, and wear resistance to polymers.
IOTA 2030 is a hydroxypropyl silicone oil (double-end hydroxy-terminated) containing reactive primary hydroxyl groups at both molecular terminals. It can be used as a chain extender or comonomer in polyurethane, polyester, and other systems, introducing silicone segments into the polymer backbone, thereby significantly enhancing surface properties and overall mechanical performance.
Appearance: Colorless or yellow transparent oily liquid

Note: Other specifications can be customized according to customer requirements.
Improved Low-Temperature Flexibility: Silicone segments effectively lower the glass transition temperature of polymers, enhancing low-temperature impact resistance.
Enhanced Processability: Reduces melt viscosity, improving flowability and mold filling capacity during processing.
Anti-Blocking / Release Properties: Utilizes the automatic surface migration effect of silicones to provide excellent release, anti-blocking, and anti-graffiti properties to material surfaces.
Increased Temperature Resistance: Silicone segments enhance thermal stability and aging resistance of polymers.
Improved Wear Resistance: Reduces surface friction coefficient, enhancing scratch resistance of coatings or products.
Anti-Graffiti Additives: Used in coating systems to provide easy-to-clean, anti-graffiti surfaces.
Release Agents / Mold Release Agents: Used as internal additives or external release agents to improve separation between molds and products.
Polyurethane Modification: Used in the synthesis of silicone-polyurethane block copolymers for high-performance elastomers, coatings, and adhesives.
Polyester Modification: Improves flexibility, weatherability, and surface feel of polyester resins.
Surface Treatment Agents: Used for softening and smoothing finishing of textiles, leather, paper, and other substrates.
The IOTA 2030 series provides a customizable reactive silicone platform for polymer modification through precise control of molecular weight and functionality.
