Molecular Structure Innovation: Directed Anchoring and Long-Lasting Adhesion
Block silicone oils utilize a unique siloxane-polyamine-polyether ternary copolymer structure to form a targeted adsorption layer on the fiber surface. The strong interaction between the cationic amino groups and the fiber's hydroxyl/carboxyl groups allows the siloxane backbone to be fixed to the fiber surface in a "molecular lock" fashion, resulting in over 30% stronger adhesion than the physical adsorption of conventional amino silicone oils. After high-temperature baking at 150°C, the resulting cross-linked mesh film can withstand over 50 industrial washes, representing a washability twice that of conventional silicone oils. This structural characteristic makes it an excellent choice for finishing synthetic fibers such as polyester and nylon, making it particularly suitable for high-use applications such as sports fabrics and outdoor gear.

Performance Breakthrough: Multi-Dimensional Improvements in Fabric Quality
Improved Touch: Fabrics treated with block silicone oils have a static coefficient of friction reduced to below 0.12, and a dynamic coefficient of friction within the 0.08-0.10 range, achieving a soft, "cloud-like" feel. Experimental data shows that its bulk is 25% higher and its smoothness is 18% higher than amino silicone oil, making it particularly effective in demanding fabrics such as coral fleece and cashmere blends.
Environmentally Compatible: Its APEO/NPEO-free formula complies with EU REACH regulations and Oeko-Tex Standard 100 certification. Bio-based products such as Siligen® EH1 contain 35% plant-based ingredients and less than 0.1% D4/D5/D6 siloxanes, meeting ZDHC zero-emission standards.
Process Compatibility: Its self-emulsifying system withstands extreme pH conditions of 3-12 and can be used in the same bath with anionic dyes and optical brighteners without demulsification. In complex processes such as cheese dyeing and reactive printing, it avoids defects such as silicone spots and roller sticking, increasing yields to over 98%.

Expanding Industry Applications: From Textiles to Cross-Industry Innovation
In the daily chemical sector, segmented silicone oils have been used in conditioners and lotion formulations. Their low-yellowing properties ensure whiteness retention of over 95% on white fabrics. In the industrial sector, its use as a plastic release agent can shorten injection molding cycles by 15% and improve the surface finish of rubber products by one grade. This material's adaptability in multiple scenarios is driving its transformation from a textile auxiliary to a functional material, with the global market expected to exceed US$800 million in 2025.
