DSTDP exudation to product surface
Fenómeno del problema
White DSTDP powder exudes on the plastic product surface
Análisis de la causa
DSTDP thioester type has poor compatibility with the base resin; addition amount too high >0.5wt%, supersaturated exudation
Solución
1) Reduce DSTDP to 0.2-0.3wt% to reduce exudation; 2) use more compatible antioxidant 168 to replace part of DSTDP; 3) raise processing temperature to promote dispersion and reduce exudation
Conclusión clave
DSTDP exudation is caused by poor compatibility and excessive addition; reducing amount and improving compatibility are key
