APPLICATION NOTE: ELECTRICAL FLAT SHEET
The Electrical Flat Sheet (EFS) Process is a unique variation of compression molding. Laminates are typically made in sizes up to 4 foot by 8 foot sheets with thickness between 1/16 inch and 6 inches.
Sheets are often then cut into various shapes for electrical insulators such as automotive electrical components, by power companies for transformer isolation, buss bars and large equipment requiring proper electrical isolation.
SI VEIL DESIGN CONSIDERATIONS
Pearlveil is uniquely designed for EFS applications, including:
Veil Thickness / Weight:
Final design should be determined after sample part testing. Typical SI Veils frequently used will range between 10 mil and 20 mil thick.
SI Veils may be specified up to 120 inches (3.048 m) wide.
All lightweight veils are non-woven, continuous strand glass fibers that provides excellent wet out and helps elimination air entrapment in
All SI Veils are clear in color, making the glass transparent in the finished part.
Series 100 Binder is more soluble and usually selected for Continuous Laminating.
Series 600 Binder may be selected if the process requires higher tensile properties.
Other: Consult Factory.
Pearlveil offers excellent electrical resistance for finished parts.
All SI Veils highly corrosive resistant for parts intended for use in harsh, acidic conditions.
Pearlveil provides outstanding laminate finishes eliminating optical distortion of printed fabrics.
Smoke and Fire Suppression:
All SI veils consist of glass mineral fibers that are non-toxic and do not burn.
Post Lamination Finishing:
- The translucent color allows for enhanced resin pigmentation or post painting
- Parts can be sanded before post painting
- The glass fibers shear cleanly when holes are punched into the part
Each roll is attached and wound on a heavy duty 4-inch I.D. cardboard core, immediately sealed against contamination in a polyethylene bag and identified with a unique product specific label.
Pearlveil, based upon quantities, is usually shipped on a 45 inch x 45 inch wooden pallet. Optional packaging is available.
For best performance, all veils should be stored upright in locations with temperatures between 50F (10C) and 90F (35C) and relative humidity elow 80%.
All Pearlveil products are produced in the United States and meets the demanding quality requirements within the industry.
