CUSTOM FILLING COMPOUNDS TO FIT YOUR NEEDS
Custom versions of Mastergel can be formulated to meet your unique specifications. Using your engineering design requirements and desired processing parameters, Master Adhesives can design and manufacture a product that precisely suits your needs. Also ask about the various standard versions of Mastergel we have available.
BENEFITS OF MASTERGEL
- Takes advantage of proprietary formulation and manufacturing technology to produce a state-of-the-art material at a lower cost per unit volume than competitive products
- Designed to pass the BELLCORE and REA 80°C drip test, while maintaining a low degree of stiffness and allowing high processing speeds
- Allows you to broaden the processing window while maintaining low attenuation at or below -40°C
- Allows you to maintain consistently low levels of excess fiber length
SUBSTRATE COMPATIBILITY
Mastergel compounds are compatible with a variety of substrates, including but not limited to:
- PBT
- Polypropylene
- Polyethylene
Tests have proven Mastergel to be more compatible with polypropylene than any other fiber optic cable filling compound. And Mastergel can be used in a variety of cable designs, including:
- Loose Tube
- OPGW
- Submarine
- Ribbon Cable
