Technical Details & Test Data
- Processing
By conventional thermoplastic injection molding using temperatures set in the range 200°–250°C. It is essential to minimize molding stresses since these may be released during elevated temperature cure or service, causing warpage.
Crosslinking –In Hot Water at 95°- 100°C 1mm Thickness 5 Hours 2mm Thickness 12 Hours 3mm Thickness 24 Hours - Color Masterbatches
CM488/6 catalyst masterbatch is normally added at 5% to 95% of SX739 graft.
Addition of approved color masterbatches, including black, up to a maximum of 1%, has no detrimental effect on the properties or crosslinking capability.
It is recommended that all masterbatches, including those containing the catalyst, should be thoroughly dried at 60°C for 8 hours or at 80°C for 4 hours.
Packaging & Availability
- Packaging
The following possibilities are available:
- Moisture resistant sacks containing 25kg
- Boxes with a moisture resistant heat sealed liner containing approximately 500kg
Storage & Handling
- Storage & Shelf Life
SX739 normally has shelf life of at least 6 months from the date of manufacture. The storage of silane cross-linkable compounds in cool dry conditions will maximize useful shelf life. Other precautions are:
- Packaging should remain sealed
- Avoid temperatures above 35°C
- Avoid storage outside and in direct sunlight
- Use within 8 hours of opening packaging
