DSTDP poor chemical resistance
Fenómeno del problema
DSTDP product mechanical properties decrease >30% after immersion in acid/alkali solvents
Análisis de la causa
DSTDP has high affinity for specific chemicals, eroded and swollen; DSTDP molecular chains attacked by chemicals and broken
Solución
1) Select chemical-resistant grades; 2) slight crosslinking to reduce swelling; 3) product surface coating protection; 4) add chemical stabilizer
Conclusión clave
Poor chemical resistance is caused by DSTDP chemical affinity; selecting chemical-resistant grades and coating are key
