Built for the grid
Utilities Manufacturing
Molded insulating and weather-sealing components for transmission, distribution and substation hardware.
How we support utilities programs
Utility components sit outdoors for decades. SYNC compounds elastomers for UV, ozone and temperature-cycling resistance, then molds and tests them against the dielectric and weathering requirements your specification calls out.
Large-format compression molding at Blackstone handles the oversized parts other shops turn away, up to 46 x 46 inches, without splitting a single component across multiple tools.
Typical applications
Parts we make for this market
- Insulating boots and covers
- Weather seals and gaskets

- Bushings and pads
Materials
Commonly specified compounds
- EPDM
- Silicone (VMQ)
- Neoprene (CR)
- Nitrile (NBR)
- SBR
We compound in house, so this list is a starting point rather than a catalog. If your application needs a formulation that does not exist yet, that is a conversation we are set up to have.
