Processing Guidelines
| Parameter | Recommended Conditions |
|---|---|
| Drying | Not normally required; if needed, dry at 80-100°C for 2-3 hours |
| Injection Molding Temperature | 260-300°C |
| Extrusion Temperature | 260-300°C |
| Mold Temperature | 40-80°C |
Critical Processing Warnings:
-
Drying: TPX MX001 is not hygroscopic and typically does not require drying. If moisture is a concern, dry at 80-100°C for 2-3 hours.
-
Recommended Processing: Suitable for injection molding and extrusion processing by profile, mandrel, pipe and film.
-
Gate Design: Pin gate is the most suitable for TPX molds due to excellent flowability. Avoid large gates that can cause residual stress and gate cracks.
-
Cooling: Sufficient and well-balanced cooling channels are essential due to TPX’s crystalline nature and larger shrinkage compared to amorphous polymers.
-
Surface Finish: Highly polished mold surface is recommended for excellent transparency.
-
Shrinkage: Mold design should account for higher shrinkage. Off-center gates are recommended to prevent warpage.
-
Regrind: Regrind can be used up to 20-30% with virgin material, provided it is clean and properly dried.
