- Processing
- VESTAKEEP® 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 370°C and 380°C during the injection molding process. The mold temperature should be within a range of 160°C to 200°C, preferably 180°C.
