Silicone Gasket Manufacturer

Silicone Gasket Manufacturer

Custom-manufactured silicone gaskets engineered for medical devices and electronics assemblies where biocompatibility, electrical insulation, and temperature stability prevent system failures.

Medical-Grade and Electronics-Rated Gaskets rom -67°F to 450°F

Colvin Friedman manufactures silicone gaskets for two critical applications: FDA-regulated medical devices and electrical-insulated electronics housings. Our gaskets meet USP Class VI biocompatibility standards or have a dielectric strength of 370 to 500 V/mil. We specialize in igh-volume precision die-cutting of silicone sheet material using flatbed or rotary processes. Every component is application-specific; we do not sell catalog products.

Property Specification Benefit
Operating Temperature -67°F to 450°F Maintains seal integrity across temperature extremes
Dielectric Strength 370-500 V/mil Prevents current leakage in electronic assemblies
Biocompatibility USP Class VI-compliant options Safe for direct contact with pharmaceutical products or human tissue
Compression Set at 392°F 15-25% after 22 hours Retains sealing force under sustained compression and heat
Tear Resistance 50-150 ppi Withstands installation stress without compromising seal geometry

Why Medical and Electronics Manufacturers Specify Silicone

Medical and electronics manufacturers choose silicone for its unique combination of biocompatibility, electrical insulation, durability, and chemical resistance, ensuring reliable performance in demanding applications.

Why Choose Colvin Friedman

With over 70 years of high-volume production experience, our operators understand exactly how silicone material performs under different cutting methods, delivering tight tolerances at scale. Our U.S. based manufacturing eliminates overseas shipping delays, keeping lead times to days instead of weeks. Engineers communicate directly with owner Josh on tolerances and material selection; no account manager layers are involved. This hands-on process control has resulted in zero recorded quality rejections.

Our Manufacturing Process

Our manufacturing process delivers precision and consistency from engineering review through final delivery:

01

Engineering Review

Submit technical drawings with tolerance callouts, material specifications, and volume requirements. We evaluate manufacturability and recommend the appropriate silicone grade, including FDA or USP Class VI certification requirements if needed.

02

Die Tooling Fabrication

Custom dies are manufactured to your exact geometry, accounting for material compression characteristics and silicone-specific cut behavior.

03

Production Run

Gaskets are die-cut using flatbed or rotary equipment, depending on material thickness and volume.
Operators monitor dimensional accuracy throughout production runs.

04

Quality Verification

The first article inspection confirms that the dimensions match the specifications. In-process checks maintain consistency across the full quantity.

05

Delivery

Gaskets are packaged to prevent contamination and damage. Delivery timing aligns with your production schedule.

Material Selection Considerations

Medical Device Applications

  • Use USP Class VI-certified silicone for gaskets that contact pharmaceuticals or sterile fluids.
  • Certification provides documentation for FDA submissions.
  • Standard medical-grade silicone (without USP certification) works for equipment housings or tubing connections where no direct fluid contact occurs.

Electronics Applications

  • High-dielectric-strength silicone provides electrical insulation between circuit boards and metal housings.
  • Thermal interface silicone pads combine sealing and heat dissipation, making them ideal for power electronics.

Temperature Performance

  • Standard silicone handles continuous operation from -67°F to 400°F with intermittent peaks to 450°F.
  • Specialized formulations extend peaks to 500°F but reduce low-temperature flexibility.

Compression Set Behavior

  • Plan flange bolt torque to achieve 15 to 25% compression without crushing the material.
  • Silicone recovers 75-85% of its original thickness after thermal cycling (22 hours at 392°F), preventing the formation of leak paths.

Projects from garage inventors to established OEMs receivethe same technical review process.

Frequently Asked Questions

Standard silicone gaskets function continuously from -67°F to 400°F, with intermittent exposure capability to 450°F. Specialized formulations reach 500°F intermittently but trade some low-temperature flexibility. Your specific operating conditions determine the appropriate grade selection.

USP Class VI certification verifies biocompatibility through extractables testing, showing the material releases minimal chemicals when exposed to biological fluids or pharmaceutical products. Medical device manufacturers specify this certification when gaskets will contact sterile fluids or human tissue.

Silicone gaskets deliver dielectric strength rangingfrom 370 to 500 volts per mil, depending on formulation and thickness. This property prevents electrical current from passing through the material, protecting circuit boards and electroniccomponents from shorts.

The compression set measures how much a gasket loses in thickness when compressed over time at elevated temperatures. Silicone shows 15 to 25% compression set after 22 hours at 392°F, with 75 to 85% of the original thickness recovered. This recovery maintains sealing force during thermal cycling and prevents leak paths.

Tolerance capability depends on material thickness, gasket geometry, and production volume. Submit your technical drawings during engineering review, and we will confirm achievable tolerances for your specifications.
