Critical Processing Warnings:
Injection Molding & Extrusion: TPX MLL411 is suitable for injection molding and extrusion processes, including mandrel, pipe, and profile extrusion .
Drying: Proper drying is critical to prevent hydrolysis and achieve optimal mechanical properties.
Low Shrinkage Control: TPX has a high mold shrinkage of 1.5–3.0% . Part and mold design should account for this characteristic. The mineral-filled structure promotes more uniform shrinkage behavior.
Mold Release: TPX MLL411 offers superior releasability with a surface tension of 24 mN/m , facilitating easy part ejection.
Storage: Store in original, sealed packaging in a cool, dry place away from direct sunlight.
