Processing Methods
Drying Treatment: POE generally has low moisture absorption. Drying may not be required if the material is stored under dry conditions with intact packaging. Drying shall be performed if the package is damaged and the material is exposed to air.
Blending Modification: For toughening by blending with base resins such as PP and PE, pre‑blending of POE and base resin is recommended to achieve uniform dispersion.
