1. Process Parameters
The following sections provide information and general recommendations for processing ELASTRON. Please keep in mind that your experience with your machines and the particular machine processed should always be taken into consideration as well. As ELASTRON compounds are frequently custom-developed to individual customer requirements, differences in processing can result.
Our applications engineers will be happy to provide any advice you may require and to come to your plant upon request to observe processing of sample materials.
2. Process Temperatures
Typical blow moulding process parameters for ELASTRON are as follows:
Feed zone: 150° C – 170° C (300° F – 340° F)
Compression zone: 185° C – 200° C (365° F – 390° F)
Metering zone: 185° C – 200° C (365° F – 390° F)
Head: 185° C – 215° C (365° F – 420° F)
Die: 185° C – 215° C (365° F – 420° F)
Mould: 10° C - 50° C (50° F - 120° F)
The maximum processing temperature should not exceed 250° C (480° F).
Overheating, i.e. thermal decomposition of the material, is easily recognized as indicated by a distinctive odour.
3. Die Temperature
The die temperature should normally be between 185° C – 215° (365° F – 420° F), depending on the compound processed. Our applications engineering department will also be pleased to provide you further information upon request.
* Except bondable grade.
** Drying at 80ºC for 2 hours is recommended.
