Product Details

Yangchen Tech’s SMA Copolymer Powder is a high-performance thermoplastic resin synthesized through advanced polymerization of styrene and maleic anhydride. Designed for versatility, this copolymer combines exceptional thermal stability, solubility, and compatibility, making it ideal for applications in coatings, adhesives, engineering plastics, and pharmaceuticals. With customizable maleic anhydride (MA) content (10–50%), our SMA copolymer offers tailored solutions to meet diverse industrial demands.  

 

Key Features:

  • Thermal Stability: High glass transition temperature (Tg: 160-210°C) ensures performance under extreme conditions.  
  • Solubility: Compatible with polar solvents (e.g., acetone, THF) and blends seamlessly with polymers like PVC and ABS.  
  • Reactivity: Free anhydride groups enable crosslinking, grafting, and surface modification.  
  • Powder Form: Easy handling, storage, and integration into formulations.
