Say Goodbye to Side Reactions and Ensure High Quality! Allyl Polyoxyethylene Polyoxypropylene Methyl End Capping is Here

October 23, 2026

In the synthesis of poly-modified silicones, do you often encounter this pain point? During the hydrosilylation reaction, the active hydrogen of the terminal hydroxyl group easily reacts with the silicone-oxygen bond, leading to increased product viscosity, reduced active content, and even compromised storage stability.

To solve this industry challenge, Hangzhou Danwei Technology proudly presents the Allyl Polyoxyethylene Polyoxypropylene Methyl End Capping Series. Through precise terminal hydroxyl methyl-capping technology, we provide you with more efficient and stable compounding solutions!

 

Core Advantage: Methyl Capping for Enhanced Performance

By replacing the active hydrogen of the terminal hydroxyl group with a methyl group, this series effectively eliminates side reactions between the hydroxyl group and the silicone-oxygen bond during hydrosilylation. This not only significantly reduces product viscosity and increases active content, but also greatly improves the overall quality of poly-modified silicones. Its excellent storage stability makes it particularly suitable for demanding applications that require long shelf lives or involve complex conditions such as hydrolysis.

Diverse Models for Precise Matching

To meet various R&D and production needs, we offer a comprehensive product matrix—there is always one that fits your formulation system:

Wide Applications Across Multiple Industries

Thanks to its excellent chemical properties, this series is widely used in:
Polyurethane foam stabilizers, emulsifiers for industrial and personal care products, coating leveling agents, hydrophilic anti-static softening finishes for textiles, self-emulsifying defoamers, water-soluble lubricants, glass anti-fogging agents, and crosslinking sealants. In addition, Si-C type poly-modified silicones are ideal raw materials in the field of chemical fiber finishes.
