Dow Wire & Cable  DFDB-5410 BK - Dow Plastics - 

DFDB-5410 Black is a carbon black filled masterbatch developed for use with SI-LINK™ PE. This carbon black masterbatch is especially designed to provide excellent UV protection and to minimize the amount of moisture it absorbs.

Advantages:
DFDB-5410 BK has excellent handling and processing advantages when used in SI-LINK Polyethylene insulation system applications:
- Formulated with a processor to use less.

Specifications:
DFDB-5410 Black, when used in conjunction with the SI-LINK PE Crosslinkable Polyethylenes, provides carbon black for UV protection. To achieve 2.5% carbon black in the final product, DFDB-5410 Black should be incorporated at a level of 6.3%.

Processing Techniques:
Highly filled systems with carbon black are inherently hygroscopic and will, over a period of time, absorb moisture. Though the packaging used for DFDB-5410 Black is specifically designed to reduce moisture penetration, drying for 4 to 6 hours at 140°-160°F (60°-70°C) in a hopper dryer with dehumidified air is recommended for optimum results. If desired, it may be dry mixed with DFDB-5480 Natural catalyst masterbatch from Dow prior to being dried.
