Vinyltriethoxysilane (VTEO) | Eco-Friendly Silane Crosslinker | CAS 78-08-0
Overview
Vinyltriethoxysilane (VTEO), widely known as A-151, is a clear, colorless, and highly versatile bifunctional organosilane. While it shares the same reactive vinyl group as VTMO, its defining advantage lies in its ethoxy groups. Upon moisture-triggered hydrolysis, VTEO releases ethanol instead of toxic methanol. This critical distinction makes it the ultimate eco-friendly crosslinking agent for applications demanding stringent health, safety, and environmental (HSE) compliance.
Product Description
Vinyltriethoxysilane (VTEO) | Eco-Silane Crosslinker
Product Overview
Vinyltriethoxysilane (VTEO), widely known as A-151, is a clear, colorless bifunctional organosilane. While it shares the same reactive vinyl group as VTMO, its defining advantage lies in its ethoxy groups. Upon moisture-triggered hydrolysis, VTEO releases ethanol instead of toxic methanol. This critical distinction makes it the ultimate eco-friendly crosslinking agent for applications demanding stringent health, safety, and environmental (HSE) compliance.
At Shandong Yinglang Chemical Co., Ltd., established in 2016, we supply bulk volumes of Premium High-Purity VTEO (≥ 99.0%) to the world's leading drinking water pipe manufacturers and eco-friendly cable compound formulators. Operating securely under Class 3 Dangerous Goods protocols, our VTEO is packaged under absolutely dry, Nitrogen-blanketed conditions to prevent premature hydrolysis, ensuring flawless crosslinking performance in your extrusion processes.
Technical Specifications (COA)
For safe drinking water pipes and stable sealant formulations, exceptional purity and strict moisture exclusion are mandatory. Typical specifications:
| Purity (VTEO) | ≥ 99.0% |
|---|---|
| Color (Pt-Co) | ≤ 20 |
| Density (at 20°C) | 0.900 - 0.910 g/cm³ |
| Refractive Index (at 20°C) | 1.395 - 1.397 |
| Chlorides | ≤ 10 ppm |
Key Applications
- PEX-b Drinking Water Pipes: The premier crosslinking agent for PEX-b pipes. Because it yields non-toxic ethanol during curing, it easily meets stringent global hygiene standards for potable water systems.
- HFFR & Eco-Friendly Cables: Used in the silane-grafting of Halogen-Free Flame Retardant compounds, ensuring worker safety during cable extrusion.
- Safer Moisture Scavenger: Acts as an effective, low-toxicity water scavenger in PU and silicone sealants designed for indoor applications.
- Adhesion Promoter: Enhances interfacial adhesion between inorganic fillers and organic polymer matrices.
🌱 Compliance with Global HSE Standards
As European (REACH) and global safety regulations tighten around the emissions of toxic methanol in manufacturing facilities, transitioning from VTMO to VTEO is a strategic necessity. Yinglang Chemical’s VTEO allows your silane-grafting lines to operate safely, releasing only benign ethanol vapor. This not only protects your factory workers but also guarantees that your final PEX-b pipes and HFFR cables can pass the most rigorous international toxicity and environmental certifications.
Strict Moisture-Barrier DG Packaging Options
Because VTEO hydrolyzes upon contact with ambient moisture, we utilize strictly sealed packaging for global ocean transit:
- 1000 KG IBC Totes with specialized moisture-barrier valves (Recommended for massive PEX pipe production).
- 190 KG / 200 KG UN-approved Steel Drums, tightly sealed and strictly Nitrogen-blanketed.
- ISO TANKS (20 MT) available for continuous, large-scale industrial procurement.
⚠️ Safety & Transport Information (Class 3 DG)
- Transport Classification: Classified as Class 3 (Flammable Liquid).
- UN Number: UN 1993 | Packing Group: III
- Handling Precautions: FLAMMABLE LIQUID AND VAPOR. Reacts with moisture to release Ethanol. Handle in explosion-proof, completely dry systems. Store in a cool, well-ventilated DG facility away from water.

FAQ
Q1: What documents and certifications do you provide?
A Standard shipment includes COA (Certificate of Analysis) and MSDS (SDS). We also provide ISO 9001 certification and support third-party inspections like SGS or BV upon request.
Q2: Do you provide custom synthesis or formulation services?
A Yes. If you have specific purity requirements or a unique formulation, our R&D team can provide custom synthesis and adjust the stabilizers/inhibitors to meet your technical specifications.
Q3: What are your terms of payment?
A
For Orders ≤ $1,000: 100% in advance.
For Orders > $1,000: 30% T/T in advance, and the balance before shipment or against the copy of B/L. Irrevocable L/C at sight is also acceptable for bulk orders.
Q4: How long is your price valid?
A Chemical prices fluctuate due to the changes in raw material costs and exchange rates. Please contact our sales team for the latest real-time quotation.
Q5: What packaging and shipping ports are available?
A
We normally ship from Qingdao, Shanghai, or Ningbo.
