Downstream process integration

• Introduced in condensation or substitution reactions forming the liquid crystalline monomer core; used post-purification of major fluorinated intermediates

Final product types

• Twisted nematic and super-twisted nematic LCD monomers
• Specialty fluorinated liquid crystal mixtures for mobile and TV displays
• Low-voltage/high-stability display compounds

4. Advanced Polymer Modifier Manufacturing

In specialty polymer production, this compound enables side-chain fluorination, conferring chemical resistance, surface energy adjustment, and tailored dielectric properties for electronics and membrane markets. Process consistency must address residual halogen control, since this impacts both end-polymer shelf life and electrical properties. Downstream users require full traceability from monomer introduction through finished polymer testing.

Industry compliance standards

• ISO 9001 for quality management systems
• REACH Regulation (EC) No 1907/2006 for chemical safety data and registration
