- Processing
- VESTAKEEPĀ® L 4000 G can be processed by common machines for thermoplastics.
- The additional lubrication agent improves the feeding process.
- We recommend a melt temperature between 370Ā°C and 380Ā°C during the injection molding process. The mold temperature should be within a range of 160Ā°C to 200Ā°C, preferably 180Ā°C.
