Manufacture of high quality dielectric joints, insulators and protections for the electronics industry.Our main goal is to continually exceed the expectations of our customers by providing high performance gaskets and sealing products at competitive prices.


Extensive experience in the manufacture of die cutting, blade, water jet and laser cutting. We can also offer numerous secondary operations including pre-cutting, folding, bending, embossing, printing and pressure sensitive adhesive (PSA) to meet their manufacturing needs. CPI Sealing has the ability to produce high quality components, custom and insulating parts, which are used in applications such as:

  • PCB
  • Keyboards
  • Lighting devices
  • Telecommunications (Mobile Devices)
  • Static shield
  • EMI RFI armor
  • Electronics devices
  • Electrical controls
  • LCD screens
  • Timers
  • Power Supplies
  • Heat dissipation
  • Antistatic insulation
  • Electronic instruments

We offer high performance parts that meet UL, chemical resistant insulation. We are professional technical guidance of boards that require extensive knowledge of insulating materials. We work closely with customers to create electrical components tailored to meet your exact specifications.

Electrical insulation materials

We maintain a complete line of electrical insulation materials. We manufacture electrical insulators, such as; packing’s, gaskets, washers, strip and custom parts. The electrical insulation materials are available in a wide range of thicknesses, hardness, density, and colors. Most insulating materials are available with or without pressure sensitive adhesive (PSA). The most commonly used insulating materials are:

  • Mylar® (Polyester)
  • Kapton®
  • Nomex®
  • Fish Paper®
  • VHR-115®
  • Hitex®
  • Valox®
  • Teflon® (PTFE)
  • Formex® GK
  • Statex®
  • Ragtex®
  • E-FR®
  • Berquist®
  • Lexan® Polycarbonate
  • Phenolics (CE, LE, G10/FR4)
