Description
The CMPure CMPD advanced melt blown depth cartridges are specifically optimized for CMP slurry systems resulting in highly consistent and repeatable filter performance. CMPD filters feature our proprietary CoLD fiber melt blowing technology, which integrates Co-Located Large Diameter fibers within the fine fiber matrix to produce a rigid structural network to the cartridge. As a result, CMPD filters provide outstanding structural strength, resistance to contaminant unloading and exceptionally long service life.
- All polypropylene construction
- Continuous gradient pore structure for built-in prefiltration
- Compatible with metal (W, Cu, Al), oxide and STI slurries
- Available also as disposable filter capsules
