(East Haven, Conn., U.S.) is a manufacturer of thermoset composite materials based on lamination and impregnation technology made under National Electrical Manufacturers Association (NEMA) specifications, namely tubing, rods, spacers, standoffs, sheet, ESD and copper-clad products.

The company says it manufactures laminated sheets from thermosetting resins (phenolic, melamine and epoxy). Base materials used for the laminated products include glass fabric, cellulose paper, cotton fabric and carbon fiber of different weaves and grades depending upon customer requirements.

Prepreg materials are cut into 3' x 4' and 4' x 8' size sheets. Final laminates are produced via hand layup with required thickness and color. Once the layup process is complete, the prepreg plies are placed inside a hot press machine and cured to produce final laminates. The materials feature high heat resistance, impact and tensile strength and dimensional stability, as well as excellent dielectric strength, machinability and optimized flame resistivity.

Current’s facility features “state-of-the-art” equipment — a majority of which is designed in-house — and two spacious, modern plants designed for maximum operating efficiency to produce higher quality products. Tubing, spacers and 4' x 8' sheets are manufactured in Current’s main plant, while its second, Ohio-based plant manufactures 3' x 4' copper-clad (PCB) and laminated sheets. Recently, the company added a filament winding technique to its production system for making carbon and glass fiber tubes in longer lengths.

Laminated products with high electrical and mechanical characteristics and different color combinations are possible. Current says its materials have been widely used in electrical, automobile, marine, construction, architecture, military, medical and aerospace applications.
