THEIC | High-Temperature Triazine Crosslinker | CAS 839-90-7
Overview
THEIC, chemically known as Tris(2-hydroxyethyl) isocyanurate, is a highly reactive, white crystalline powder characterized by its extremely stable triazine ring structure and three terminal hydroxyl groups. This unique molecular architecture makes THEIC an elite crosslinking and modifying agent. When incorporated into polymer networks, the robust triazine core imparts unparalleled thermal stability, exceptional electrical insulation, and superior mechanical flexibility, significantly upgrading the performance class of downstream materials.
Product Description
THEIC, chemically known as Tris(2-hydroxyethyl) isocyanurate, is a highly reactive, white crystalline powder characterized by its extremely stable triazine ring structure and three terminal hydroxyl groups. When incorporated into polymer networks, the robust triazine core imparts unparalleled thermal stability, exceptional electrical insulation, and superior mechanical flexibility, significantly upgrading the performance class of downstream materials.
At Shandong Yinglang Chemical Co., Ltd., established in 2011, we supply bulk volumes of Premium THEIC to multinational wire enamel formulators and advanced PVC heat stabilizer compounders. Shipped globally as highly cost-effective Non-Dangerous Goods, our THEIC is manufactured under strict quality controls to ensure ultra-low moisture and consistent hydroxyl values, guaranteeing flawless crosslinking efficiency in your high-temperature resins.
For precision wire enamels and transparent PVC stabilizers, strict control over melting point and moisture is critical. Typical specifications:
| Purity (THEIC) | ≥ 99.0% |
|---|---|
| Hydroxyl Value | 620 - 645 mg KOH/g |
| Melting Point | 133°C - 137°C |
| Moisture / Loss on Drying | ≤ 0.5% |
- High-Temperature Wire Enamels: The absolute core application. Reacted into polyester/polyesterimide varnishes to upgrade copper wire enamels to Class F (155°C), Class H (180°C), and Class C (200°C+), crucial for motors and transformers.
- PVC Heat Stabilizers: Acts as a highly effective synergistic co-stabilizer. It captures HCl during PVC processing, drastically improving long-term heat resistance and color retention of PVC pipes and cables.
- Specialty Polyurethanes: Utilized as a high-performance crosslinking polyol in the synthesis of heat-resistant polyurethanes and industrial coatings.
- Eco-Friendly Plasticizers: Used to synthesize THEIC-based ester plasticizers with low volatility.
For manufacturers of enamelled copper wires used in EV motors or heavy-duty transformers, thermal breakdown is the ultimate failure mode. Standard polyester resins simply cannot withstand continuous 180°C+ operating temperatures. By integrating Yinglang Chemical’s High-Purity THEIC into your resin synthesis, you introduce an indestructible triazine ring into the polymer backbone. This fundamentally elevates the thermal decomposition threshold, providing your insulating varnishes with extreme heat shock resistance, mechanical flexibility, and flawless dielectric performance under severe load.
As a stable crystalline solid, we offer cost-effective and secure bulk packaging for global ocean transit:
- 25 KG Multi-wall Kraft paper bags with heavy-duty PE inner liners (Tightly sealed to prevent moisture ingress).
- 500 KG / 1000 KG Jumbo Bags (FIBC) highly recommended for continuous, large-scale industrial resin manufacturing.

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.
Standard packaging includes 200kg Drums or 1000kg IBC Totes. We ensure strict safety compliance for both general and hazardous chemical cargoes.
Q6: It's my first time importing chemicals — can you help?
A Absolutely. Importing chemicals requires specific documentation. Our experienced logistics team will assist you with the entire process, including handling customs clearance documents and arranging the most suitable shipping method.
