[Introduction]
In the production of poly-modified silicones, the active hydrogen of terminal hydroxyl groups often leads to side reactions during hydrosilylation, affecting product viscosity and active content.
Today, Hangzhou Danwei Technology brings you a core raw material that effectively solves this pain point — Allyl Polyethylene Glycol Polypropylene Glycol Methyl Ending.

[Product Profile]

• Structural Formula: CH2=CHCH2O(C2H4O)n(C3H6O)mCH3

• CAS No.: 52232-27-6

• Product Series: MW440, MW1000, MW1250, MW1280, MW1500, MW2000 (Customization available upon request)

[Core Advantages: Why Choose Methyl Ending?]
Compared with traditional polys, this product replaces the active hydrogen of the terminal hydroxyl group with a methyl group, demonstrating significant advantages in hydrosilylation reactions:
Eliminates Side Reactions: Effectively avoids the reaction between hydroxyl groups and silicone-oxygen bonds, greatly reducing side reactions.
Improves Product Quality: Reduces product viscosity and increases active content, taking the quality of poly-modified silicones to the next level.
Better Storage Stability: Especially suitable for compounding products with long storage periods or complex conditions such as hydrolysis.

[Wide Applications: One Material, Multiple Uses]
With excellent performance, this series can be widely used in the following fields:

• Polyurethane Industry: Foam stabilizers

• Textile Industry: Hydrophilic anti-static softening agents, chemical fiber finishes (Si-C type poly-modified silicones)

• Coatings & Personal Care: Coating leveling agents, personal care products, emulsifiers

• Other Industries: Self-emulsifying defoamers, water-soluble lubricants, glass anti-fog agents, crosslinking sealants, etc.

[Packaging & Storage]

• Packaging: 200KG iron drum, or customized according to customer requirements.

• Storage & Transportation: Transported as non-dangerous goods. Store in a dry, cool, and ventilated place, away from direct sunlight and rain.
